+ +Release Notes date: 12-Aug-2023 + + Features introduced in version 6 + ================================ +For a detailed list of new features, with illustrations, see + http://gnuplot.info/docs_6.0/NewFeatures.html + +For more example plots see + http://gnuplot.info/demo_6.0/ + +- Function blocks and scoped variables +- Larger collection of special and complex-valued functions +- New plot styles + o 2D plot style `with surface` works in 2D polar coordinates to produce a + solid-fill gridded representation of the plane. This is analogous to the + use of dgrid3d and pm3d to produce a 3D gridded surface. + o 2D plot style `with sectors` renders one annular segment ("sector") for + each line of input data. This style can generate pie and donut charts, + windrose charts, and a polar equivalent to sparse-matrix heatmaps. + o 2D plot style `with lines` now has a filter option `sharpen`. + This filter detects spikes in a function plot that would be missed or + under-represented due to coarse sampling. It adds an additional + sampling point at the location of each such peak. +- Hulls, masks, and smoothing + o A cluster of 2D points can be replaced by a bounding polygon ("hull"). + Both convex hulls and concave hulls (χ-shapes) are supported. + o Any hull or other closed path can be used as a mask to display only + selected regions of a pm3d surface or image plot. + o New smoothing option "smooth path" can be used on 2D and 3D curves + that are not monotonic on x or y. This allows smoothing of hulls. +- Named palettes + o The current palette can be saved to a named colormap for future us. + o A predefined palette named "viridis" is provided. + o Plots can specify a previously saved palette by name. + This permits the use of multiple palettes in a single plot command. + o Named palettes can be edited to contain an alpha channel. +- New built-in functions and array operations + o palette(z) returns the current RGB palette color mapping for z. + o rgbcolor("name") returns the 32bit ARGB value for a named color. + o index(Array, element) returns the first index i for which Array[i] + is equal to element. + o split("string", "separator") unpacks the fields in a string into + an array of strings. + o join(array, "separator") is the complement to split(). + It concatenates the elements of a string array into a single string. + o `stats ` yields a testable value with no error; + useful to avoid errors or warnings in scripts. +- Program control flow + o New syntax if {...} else if {...} else {...} + o XDG base directory conventions for configuration files are supported. + o `unset warnings` suppresses output of warning messages to the console. + o The `fit` command is protected by exception handling. Control always + returns to the next line of input even in the case of fit errors. + On return FIT_ERROR is non-zero if an error occurred. + o "Watchpoints" are target values associated with individual plots + in a graph. As that plot is drawn, each component line segment is + monitored to see if its endpoints bracket the target value of a + watchpoint coordinate (x, y, or z) or function f(x,y). + If a match is found, the [x,y] coordinates of the match point are + saved for later use. Possible uses include + - find the intersection points of two curves + - find zeros of a function + - find and notate where a dependent variable or function f(x,y) + crosses a threshold value + - use the mouse to track values along multiple plots simultaneously +- New terminals and terminal options + o Terminals that display graphics in the same window as text entry now + support pseudo-mousing; i.e. they respond to arrow keys and other + hot-key bindings during "pause mouse". + o New terminals kittygd and kittycairo provide in-window graphics for + terminal emulators that support the kitty protocol. + o New terminal webp generates a single frame or an animation sequence + using webp encoding. Frames are generated using pngcairo, + then encoded through the WebPAnimEncoder API. + o New terminal block for text-mode pseudo-graphics uses Unicode block + or Braille characters to offer improved resolution compared to the + dumb or caca terminals. + o latex terminals standalone mode updated to work with texlive2023 +- Miscellaneous other new features + o Time unit settings for major and minor axis tics. For example, + minor tic marks can be placed at exactly one month intervals. + o The character sequence $# in a using specifier evaluates to the total + number of columns available in the current line of data. + "plot FOO using 0:(column($# - 1))" plots the last-but-one field of each row. + o keyword binvalue=avg plots the average, rather than the sum, of binned data. + o "set colorbox bottom" places the color box underneath the plot. + o "set pm3d spotlight" adds a user-controlled spotlight to the lighting model. + o New key layout options to force specific width or number of columns. + Automatic positioning of the key on the page can be manually tweaked + by giving an offset. + o "set isotropic" adjusts the axis scaling in both 2D and 3D plots such + that x, y, and z axes all have the same scale. + o Text rotation angles are not limited to integral degree values. + o Data-driven color assignments in plot style "histograms". + + + Changes between 6.0 -rc1 and -rc2 + ================================= +* Japanese documentation updated + - added missing file title-ja.tex, build dependencies for mingw +* Support building against Qt6 + - ./configure falls back to Qt5 if the Qt6 libraries are not found +* New configure option --enable-stable-sort + - Use mergesort rather than qsort if the system provides it. + - If neither mergesort nor glibc stabe qsort is available, + modify internal gnuplot structures to contain a secondary sort key +* Render color gradient in colorbox as a pixel array + - cairo, qt terminals + + + Notes for packagers and testers + =============================== + +Obsolete or deprecated components +--------------------------------- + +The "gnuplot mode" elisp and TeX files for use with emacs are now +maintained as a separate project: https://github.com/bruceravel/gnuplot-mode +so there is no longer a configuration option --with-lisp-files. + +LaTeX-related terminal drivers latex, emtex, eepic, and tpic are no longer +built by default. Their closest equivalent is the new pict2e terminal, but +LaTeX users who want support for the full range of gnuplot plot styles are +recommended to use the cairolatex or tikz terminals. + +Configuration options for interactive use +----------------------------------------- + +The 6.0 source code supports three primary cross-platform interactive +modes in addition to several platform-specific modes. + +1) Qt + + The qt terminal supports interactive display with menu-driven + output to png, svg or pdf. If either Qt4 or Qt5 is detected by the + configure script, this will be the default terminal. It is now the + fastest and most full-featured interactive terminal option. + + To disable this terminal or force use of Qt4 even if Qt5 is present + $ ./configure --with-qt=qt4 + $ ./configure --without-qt + +2) Cairo/pango/wxWidgets + + This set of terminals includes pngcairo, pdfcairo, epscairo, and cairolatex + for output to a file. The wxt terminal provides interactive display + All of these will be built by default if the configuration script finds + the required libcairo, libpango, libcairo, libwxgtk, and related + support libraries + + To disable these terminals: + $ ./configure --without-cairo + $ ./configure --with-cairo --disable-wxwidgets + +3) X11 (the "classic" interactive interface) + This used to be the preferred interactive interface, but the newer + wxt and qt terminals offer nicer output and a wider range of features. + + +Output to files +--------------- + +Of course the terminals (output modes) present in previous gnuplot versions +are also still available. These include, among many more obscure options: + +- PostScript (*.ps or *.eps) +- svg +- png/jpeg/gif output via libgd graphics library +- png/pdf/eps output via cairo graphics library +- TeX/LaTeX including TikZ and ConTeXt +- Bitmapped output to support older devices (e.g. HP deskjet, epson, and + seiko printers, pbm bitmapped graphics files) is available if needed + but is no longer configured in by default. + ./configure --with-bitmap-terminals + +Output of inline graphics to terminal emulator or linux console +--------------------------------------------------------------- + +The sixel and kitty terminals display graphics in-line with the commands +typed in a suitable terminal emulator window. For example "xterm -ti 340" +emulates a vt340 with indexed color sixel graphics. +The KDE desktop konsole terminal provides RGB color sixel graphics +and 32-bit color + alpha channel graphics using the kitty protocol. +The yaft terminal emulator can provide sixel graphics at linux console +level with no x11 or other windowing system active. + +Generating interactive plots for web display +-------------------------------------------- + +- Mouseable output for display on the web can be created using either + the canvas terminal (HTML5 2D canvas element) or the svg terminal. + Both allow zooming, toggling plot elements on/off, and user-scriptable + hot keys. + + Other Notes + =========== + +Installation +------------ + +You can download a source tarball for the current gnuplot version +from the gnuplot development site on SourceForge. + http://sourceforge.net/projects/gnuplot + +Some platform-specific installation tips are given in the INSTALL +file of the source package; the short version for linux/unix-like +systems is to unpack the tarball and then +

+
+ +Pay careful attention to the output of the ./configure script. +It may indicate that some output modes have been omitted because the +necessary support libraries were not found.

However unlike the IEEE floating - point representation, which sacrifices precision to span a total range - of roughly [-10^307 : 10^307], integer operations that result in values - outside the range [-2^63 : 2^63] overflow. The 'set overflow' command - lets you control what happens in case of overflow. - - `set overflow` is the same as `set overflow float`. It causes the - result to be returned as a real number rather than as an integer. - This is the default. - - The command `unset overflow` causes integer arithmetic overflow to be - ignored. No error is shown. You may want this if your platform allows - only 32-bit integer arithmetic and you want to approximate the behaviour - of gnuplot versions prior to 5.3. - - The `reset` command does not affect the state of overflow handling. - - Earlier gnuplot versions were limited to 32-bit arithmetic and ignored - integer overflow. Note, however, that some built-in operators did not - use integer arithemetic at all, even when given integer arguments. This - included the exponentiation operator N**M and the summation operator - (see `summation`). These operations now return an integer value when - given integer arguments, making them potentially susceptible to overflow - and thus affected by the state of `set overflow`. - - set overflow float - ------------------ - If an integer arithmetic expression overflows the limiting range, - [-2^63 : 2^63] for 64-bit integers, the result is returned as a - floating point value instead.

Since we replace rl_getc_function by our own - routine to catch input from mouse, we should also check this flag to - invoke the real handler.

In verison 5.2 we track the data range on x1 x2 y1 y2 - separately. This caused breakage wherever the program assumed the - autoscale range on x1 (or y1) was always current. Worse, it would - propagate that range onto the secondary axis, possibly overwriting the - correct range. Now we introduce a new routine reconcile_linked_axes() - that merges the min/max values from e.g. x1 and x2 so that the - autoscaled range covers input data plotted on either axis. - Bug #1973 - - * demo/linked_autoscale.dem: Exercise the new code (fails on previous - gnuplot versions). - -2017-10-06 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/command.c: Move WEXITSTATUS fall-back definition away from here. - - * src/syscfg.h: Include <sys/wait.h>, if it exists. - (WEXITSTATUS): Provide fall-back definition, if none in - <sys/wait.h>.

It turns out that was - not true with regard to missing data. If the "missing" flag is present - in the data then 'using N' catches it but 'using ($N)' does not. - The problem is that ($N) and (column(N)) and "header_of_N" all invoke - expression evaluation, which has had no mechanism to indicate a missing - value on return rather than NaN. This patch overloads the imaginary - slot of a complex NaN value to hold DF_MISSING rather than 0.0 on return - from f_dollar() and f_column() as appropriate. For convenience the body - of f_dollar() is replaced by a pass-through to f_column() so that both - routines behave the same way. - Bug #1896 - - * src/plot2d.c (get_data) src/set.c src/show.c docs/gnuplot.doc: - The fix for bug #1896 did not address the case where a missing value is - encountered during evaluation of an expression.

This system started to - break when the border linetype LT_BLACK became the default linetype and - broke further with the addition of a new priority level for fill areas. - The core code is pretty good at issuing draw commands in the desired - order, so at this point we get better results by dropping the priority - rank and having all set_pixel operations overwrite previous contents. - - * src/graphics.c src/plot2d.c term/vgagl.trm: - Clean up typos, comments, old FIXMEs, dead code - -2016-11-29 Ethan A Merritt <merritt@u.washington.edu> - - * src/graph3d.c (do_3dplot): Front/back layering of border+grid - components was not always correct in hidden3d mode.

Minimal example: - 'set log x; plot '-'; replot' - failed to delog/log the updated min/max axis limits. - Bug #1774 - -2016-04-10 Tatsuro MATSUOKA <tmacchant3@yahoo.co.jp> - - * win/gnuplot.iss: Remove <BOM> marker from start of file, since this - makes autoconfigure fail on MinGW. >>> NB: Reverted 2016-04-21 - -2016-04-08 Bastian Maerkisch <bmaerkisch@web.de> - - * src/util.c (existdir) src/misc.c (recursivefullname): Use Windows - implementations of getdir() and friends in stdfn.c instead of platform - specific code (or the ones provided by OpenWatcom). - -2016-04-06 Ethan A Merritt <merritt@u.washington.edu> - - * term/emf.trm: Enhanced text mode was over-zealously skipping new - set_font requests if successive writes requested the same font+property. - This caused it to lose italic/bold/etc properties. - Prevent this by clearing the font history at the end of each enhanced - text write. - Bug #1772 - -2016-04-04 Ethan A Merritt <merritt@u.washington.edu> - - * src/graphics.c (process_image): There is not currently a fool-proof - mechanism for inferring image dimension from a set of x/y/z coords read - as ascii data. But we can do better than transposing the row/column - count by mistake. Note that this same transposition was previously - fixed for the case of ascii matrix data input (Bug #1654) - Bug #1767 - -2016-04-02 Ethan A Merritt <merritt@u.washington.edu> - - * src/axis.c (eval_link_function): Test for "undefined" status on - return from link evaluation. - -2016-04-01 Ethan A Merritt <merritt@u.washington.edu> - - * src/term_api.h src/graphics.c term/qt.trm: The qt terminal output - for "with image pixels" suffers from bad inter-pixel artifacts. This - seems due to use of term->fillbox() rather than term->filled_polygon(). - The qt fillbox routine is probably fixable but for now we add a - terminal flag TERM_POLYGON_PIXELS that tells the image code to use - polygons instead. - -2016-03-31 Bastian Maerkisch <bmaerkisch@web.de> - - * src/command.c (rlgets) docs/gnuplot.doc: Do not add lines to - command line history which start with a history command. - Bug #1763 - -2016-03-31 Ethan A Merritt <merritt@u.washington.edu> - - * src/history.c (add_history): The documentation states that - "set history N" will save N lines on history to a file on program exit. - This is true in practice for both the readline-based history code and - the built-in history code. However the builtin code also truncates and - renumbers the active history list in the current session. This makes - the numbers essentially useless once the list reaches N entries. - Remove this unwanted secondary effect in the built-in version. - Bug #1763. - - * src/axis.c (gen_tics): Promote logscale base from 0 to 10 on entry - rather than later having to test for nonzero each time. - -2016-03-30 Bastian Maerkisch <bmaerkisch@web.de> - - * config/mingw/Makefile: Use local version of gnuplot to generate - plots of the tutorial. - - * config/mingw/Makefile: Collecting all required DLLs for a Windows - binary package can be tedious. When activated via the DLLS=1 option, - we now try to at least automatically copy all DLLs from Mingw-w64. - Applies to targets `install`, `installer`, and `zip`. - -2016-03-29 Bastian Maerkisch <bmaerkisch@web.de> - - * src/win/wmenu.c: Remove the alternative code which would use a - modified file-open-dialog to select a directory. This wasn't working - since Vista anyway and was never included in any official binary. - - * src/command.c: The Windows specific winsystem() has been deactivated - for a long time. Remove it. - - * src/readline.c: The return value of the *_getch() functions should - be int, not char, in order to avoid confusion between EOF (-1) and - (char)0xff. - Bug 1558 - - * src/qtterminal/qtconversion.cpp: Avoid use of isnan() in C++ code. - The C++11 standard has it as a function in the std namespace, whereas - older compilers provude it as a macro or as ::isnan(). Use (var != var) - instead. - -2016-03-25 Ethan A Merritt <merritt@u.washington.edu> - - * axis.c (eval_link_function) graphics.c (plot_lines): - If map_x() or map_y() trigger eval_link_function(), it may return NaN. - In this case the mapped coordinate value is nonsense and the "undefined" - flag is TRUE. Check this flag to avoid drawing spurious line segments - in plot with lines. - - * src/axis.c src/axis.h src/plot2d.c: New routine init_sample_range(). - Always use SAMPLE_AXIS to hold bookkeeping values for function sampling, - rather than sometimes using a real axis, sometimes a parametrics axis, - and sometimes SAMPLE_AXIS. - -2016-03-24 Ethan A Merritt <merritt@u.washington.edu> - - * src/command.c (array_command): - Sanity check: array name must start with a letter. - - * src/command.c (command is_array_assignment): - Change the order of parsing: check for array assignment before trying - to interpret the first input token as a command keyword. E.g. - "array q[2]; q[1] = 1" must not interpret the initial 'q' as shorthand - for 'quit'. - Bug #1762 - -2016-03-24 Bastian Maerkisch <bmaerkisch@web.de> - - * config/mingw/Makefile: The proper way to invoke shell commands in - GNU makefiles is via $(shell ...). Using backticks relies on the - shell doing the replacement and is not always what we want. - Bug #1752 - -2016-03-21 Ethan A Merritt <merritt@u.washington.edu> - - * src/datafile.c src/datafile.h src/unset.c: The df_fgets() change - 4 days ago caused a regression because input buffer initialization was - missed in some paths. Rename the shared buffer to df_line. - Move the initialization into a new routine df_init() called via - reset_command() on program entry. - Bug #1758 - - * src/axis.c (clone_linked_axes): If an endpoint of a linked axis was - exactly zero, the forward/reverse link check would complain because of a - spurious divide-by-zero. Now we test for this case separately. - - * src/graphics.c (do_plot plot_points): The "dots" plot style is - implemented internally as pointtype 0, although this was never stated in - the documentation. Apparently some users discovered and used pointtype 0 - routinely and were unhappy that it stopped working in version 5. - Neither the original behavior nor its removal was intentional, but it is - easy enough to restore the pre-version 5 behaviour so we do it now. - Bug #1733 - -2016-03-20 Matthew Halverson <mhalver@users.sf.net> - - * src/term.c (term_set_output): Open pipes in binary mode if the - terminal has the TERM_BINARY flag set. - Bug #1756 - -2016-03-17 Ethan A Merritt <merritt@u.washington.edu> - - * src/plot2d.c: If pointtype PT_CHARACTER is the default for a plot - then allow text options like "tc rgb 'foo'" in the plot command. - - * src/command.c src/eval.c src/parse.c: Disentangle gpfree_string() and - gpfree_array(). Most callers should avoid the latter. - - * src/graph3d.c src/graphics.c src/hidden3d.c: "pt variable" point - types were off-by-1 on output. - Bug #1754 - - * src/datafile.c src/datafile.h src/datablock.c: - There was already a routine df_gets() in datafile.c that safely reads in - an arbitrary length line of data. Split this into a public function - df_fgets() and a private wrapper df_gets(). Share the public function - with data input in datablock.c:datablock_command. This removes the - limit of 1024 characters per line read in to a datablock. - -2016-03-15 Ethan A Merritt <merritt@u.washington.edu> - - * src/qtterminal/qt_term.cpp: Revise "set term qt <N> close" so that - 1) It closes window with id N but leaves the current window id unchanged - 2) It executes the command immediately rather than queueing it - Bug #1753 - - * src/qtterminal/QtGnuplotWindow.cpp: Do not set the DeleteOnClose - attribute of plot windows. This avoids an error message if you send a - new plot after explicitly closing the current plot window. - Bug #1753 #1554 - -2016-03-13 Ethan A Merritt <merritt@u.washington.edu> - - src/axis.h src/mouse.c src/save.c: Minor code cleanup for linked axes. - -2016-03-10 Ethan A Merritt <merritt@u.washington.edu> - - * src/save.c (save_link) src/save.h src/show.c: New routine so that - "show/save link" is distinct from "show/save xrange". - -2016-03-09 Allin Cottrell <cottrell@wfu.edu> - - * term/aquaterm.trm: Incorrect argument type to abs() or fabs(). - -2016-03-08 Ethan A Merritt <merritt@u.washington.edu> - - * src/axis.h src/axis.c src/command.c src/unset.c src/set.c: - Add a new field axis->linked_to_secondary so that the handling of linked - axes is more symmetric. Now you can do "set [*]range" on either end of - the linkage and the min/max/etc for the other end of the linkage will be - recalculated automatically. - - * src/axis.h src/axis.c src/boundary.c src/graph3d.c: Replace - AXIS_SETSCALE(AXIS_INDEX, ) and axis_set_graphical_range(AXIS_INDEX, ) - with a single combined routine axis_set_scale_and_range(AXIS *, ). - - * src/axis.c src/graphics.c: More cleanup and generalization of linked - axis code. - -2016-03-07 Shigeharu Takeno <shige@iee.niit.ac.jp> - - * term/tkcanvas.trm src/win/wgnuplot.mnu: Typos. - - * docs/term-ja.diff docs/gnuplot-ja.doc - src/win/wgnuplot-ja.mnu win/README-Windows-ja.txt: - Sync Japanese documentation to doc version 1.982 - -2016-03-06 Bastian Maerkisch <bmaerkisch@web.de> - - * config/mingw/Makefile win/gnuplot.iss: Support MSYS2/Mingw-w64 as - well as MSYS/MinGW and compilation using clang. Ability to build - 64bit or 32bit zip package and installer. New make flags MINGW64, - CLANG, COLOR-GCC, and M32. Default to 64bit builds when using - Mingw-w64, use M32 flag to select 32bit builds. - - * src/win/wcommon.h src/win/wgdiplus.cpp src/win/wgnuplib.h - src/win/wgraph.c: Fix several issues found by clang, with the most - important being wrong delete's in wgdiplus.cpp. - - * scanner.c (get_num): strtoll() on Windows may consume zero - characters causing an infinite loop for the input "0x". - Bug #1745 - - * src/win/wgraph.c (MakeFonts, TryCreateFont): Do not rely on GDI - supplying a sensible substitute when a requested font is not - available. Instead, fall back to the user-supplied default font or - the terminal's default font if the former is not available. - Bug #1669 - -2016-03-05 Ethan A Merritt <merritt@u.washington.edu> - - * src/wxterminal/gp_cairo.c (gp_cairo_set_linewidth): Change the - minimum linewidth supported by pdfcairo to match the other cairo - terminals. Reduce all of them to 0.20 pts (was 0.25 or 0.50). - - * src/axis.c src/graphics.c: More cleanup of linked axis code. - -2016-03-03 Ethan A Merritt <merritt@u.washington.edu> - - * src/plot2d.c (get_data): Introduction of "pt variable" increased the - maximum number of data columns for "with points" to 5. If the plot - command really does consume 5 columns, fine. But if get_data returns - 5 columns for a simple 'plot with points' command, we have to ignore the - extra columns gracefully. - Bugfix - - * src/axis.c src/axis.h src/eval.c src/eval.h: - Move eval_link_function() from eval.c to axis.c - - * src/axis.c src/axis.h src/eval.c src/eval.h src/command.c - src/graph3d.c src/graphics.c src/mouse.c src/plot2d.c src/set.c: - Revise clone_linked_axes() and eval_link_function() to use - (AXIS *) pointers rather than AXIS_INDEX. - - * src/axis.c (clone_linked_axes): Warn that the program cannot - currently handle via/inverse mapping of linked logscale axes. - Bug #1736 - -2016-03-02 Ethan A Merritt <merritt@u.washington.edu> - - * src/command.c (link_command): Accept "unset link <specific axis>" - (regression since 5.0). - -2016-03-01 Ethan A Merritt <merritt@u.washington.edu> - - * src/internal.c (f_assign): Sanity check for array index that - is found to be zero during expression evaluation. - - * graphics.c (map_position_double): Fix stupid typo that tried to map a - linked y axis through the x mapping function. This always mis-placed - objects and labels whose position is given in terms of y2 whenever y2 is - linked to y1. Furthermore placement on either x2 or y2 could be wrong if - the most recent plot did not use that same linked axis. - -2016-02-29 Ethan A Merritt <merritt@u.washington.edu> - - * src/gp_types.h src/graph3d.c src/graphics.c src/misc.c src/plot2d.c - src/plot3d.c src/save.c src/term_api.h src/hidden3d.c docs/gnuplot.doc: - Add support for "pointtype variable". If there are multiple "variable" - properties in the same [s]plot command, the order of columns in the - using spec is - [s]plot DATA using x:y:z:pointsize:pointtype:color - "pointtype variable" is only allowed with "points" or "linespoints". - Only numerical point types are possible; if you want variable character - pointtypes use "with labels" instead. - - * src/stats.c: "array A[n]; stats A" should default to single-column - analysis (equivalent to stats A using 2) since the properties of the - index are uninteresting. - -2016-02-28 Ethan A Merritt <merritt@u.washington.edu> - - * src/util.h src/util.c (common_error_exit): Move the code that resets - various gnuplot state variables after an error from int_error() to a new - common path routine common_error_exit() shared with os_error(). Ensure - that GPVAL_ERRNO and GPVAL_ERRMSG are set in both cases. - Bug #1741 - -2016-02-26 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/win/wgnuplot.mnu: Update the Windows GUI menu definitions a - bit. - -2016-02-20 Ethan A Merritt <merritt@u.washington.edu> - - * src/parse.c (parse_assignment_expression): In order to support - assignment to an array element (e.g. A[i] = foo) a slot for the - array index is always pushed onto the evaluation stack even if no - array is involved. However this slot was not being initialized to - a valid PUSHC descriptor, so "show at" and certain other - operations could fail even though they don't really care about - this dummy slot. Now we initialize it to report that a NOTDEFINED - variable was pushed. - - * src/command.c src/eval.c (push) src/internal.c src/parse.c: Back - off to the original idea that bare array names are not legal for - expression evaluation. The previous work-around of copying the - entire array on every reference imposed a huge overhead for - accessing the value of an individual entry. The previous code is - left in place via #ifdef ARRAY_COPY_ON_REFERENCE to serve as a - model for later expansion to support some subset of operations - requiring a copy (e.g. simple assigment B=A or concatenation C = - A.B). - -2016-02-18 Ethan A Merritt <merritt@u.washington.edu> - - * src/command.c src/eval.c (push): Evaluation of expressions that - contain a bare array name is problematic because any attempt to - access the actual array contents during or after evaluation - requires that they be duplicated on push() and freed - later. Freeing is the tricky part, particularly if the array - contains STRING elements. This patch seems OK in preliminary - testing, but at this point the only only possible operations are - indexing and assignment. If other operations are added later they - may reveal inadequacies in the alloc/free tracking. - -2016-02-14 Bastian Maerkisch <bmaerkisch@web.de> - - * src/wxterminal/wxt_gui.h: Use local events to avoid warnings about - incompatible linkage on Windows. - - * config/mingw/Makefile: Use MinGW's own implementations of - printf etc. which are C99 compliant. - - * src/win/wtext.h: Avoid warnings about the re-definition of - popen/pclose with fake pipe support using MSYS2/Mingw-w64. - - * src/wxterminal/wxt_gui.cpp|h: Fixes to make the wxt terminal work - with wxWidgets 3 on Windows: - 1) Disable wxWidgets debug assertions in release builds. This does - not solve the problem with a setlocale(LC_ALL, NULL) == "C" test in - wxLocale, but at least gets rid of the warning. - 2) Flush the cairo surface before blitting the internal bitmap to - screen. - - * src/win/wgraph.c: Include direct.h for _chdir(). - - * term/tkcanvas.trm (TK_init): TK_image requires WRITE_PNG_IMAGE to be - defined. - -2016-02-12 Jun Takimoto <takimoto-j@kba.biglobe.ne.jp> - - * term/tkcanvas.trm: More fixes suggested by clang warning messages. - -2016-02-11 Bastian Maerkisch <bmaerkisch@web.de> - - * term/wxterminal/wxt_gui.cpp (wxt_raise_window): On Windows, only - Restore() the window if it is iconized.

There are no other users - of this macro. - - * src/set.c src/show.c: set/show arrow length wants only a single - coordinate, not three. (See patch of 2015-12-19). - -2016-02-10 Bastian Maerkisch <bmaerkisch@web.de> - - * term/dumb.trm: Include stdint.h to make sure that uint32_t is defined - (MSVC). - - * config/config.nt config/config.nt: Sync with output of configure. - - * config/mingw/Makefile: Use gnuplot's default settings to generate - plots for the documentation. - - * configure.ac: Cairo terminals require pango 1.22 - (pango_layout_get_baseline) now.

An analogous field splot->hidden3d_top_linetype is already - maintained in (struct surface_points) for use by 3D plots. - - * src/graphics.c src/plot2d.c: In boxplots with multiple component - factors, interpret "lc variable" as requesting a new color for each - factor. - -2015-10-31 Ethan A Merritt <merritt@u.washington.edu> - - * src/util3d.c src/util3d.h (edge3d_intersect two_edge3d_intersect): - Change parameters to (coordinate *) rather than (array, index) so that - the same routines can handle clipping 3D vectors that are not stored as - successive entries in an array. - - * src/graph3d.c src/plot3d.c: Support "set clip {one|two}" for 3D - vector plots. - - * src/datafile.c (df_set_key_title): Use of columnheader(N) could - sometimes leave an extraneous character '@' in the plot title. - This was introduced in 5.0.1 as a side effect to the fix for Bug #1596. - -2015-10-28 Ethan A Merritt <merritt@u.washington.edu> - - * src/interpol.c (mcs_interp): Handle log-scaled y axis when using - monotonic cubic splines ('smooth mcs'). - - * src/plot2d.c (boxplot_range_fiddling) src/graphics.c (plot_boxplot): - Fix autoscaling of x axis if there are multiple boxplots with factors. - Bug #1696 - - * src/graphics.c (plot_points plot_boxplot): Declare and initialize - p_height and p_width locally (no code was updating the global copy). - This fixes nonfunctional "set clip points" command in version 5. - - * src/boundary.c (do_key_layout) src/graph3d.c (boundary3d): - Remove reference to p_height, p_width, which were not being initialized. - - * src/show.c (show_clip) docs/gnuplot.doc: Clarify effect of "set clip". - -2015-10-27 Ethan A Merritt <merritt@u.washington.edu> - - * Modify demos to increase coverage of gnuplot features. - line_arrows: illustrate 'set arrow from ... rto ...' - rgba_lines: illustrate 'set arrow from ... length ... angle ...' - smooth: illustrate both smooth cumulative and smooth cnorm - dashtypes: illustrate numerical dashtype definition - monotonic_spline: smooth mcs - break_continue: exercise "exit" command from inside "call <foo>" - volatile: exercise 'skip', 'volatile', 'refresh' - boxplot: illustrate 'nooutliers' - - * demo/all.dem: Call additional demos to increase code coverage. - rgba_lines fitmulti break_continue monotonic_spline volatile - -2015-10-26 Ethan A Merritt <merritt@u.washington.edu> - - * src/graph3d.c src/axis.c src/util.c src/util.h src/mouse.c - src/dynarray.c src/util3d.c src/hidden3d.c: Get rid of graph_error(). - The routine graph_error() was originally intended as a special case of - int_error() to be called "while graphics active".

Comment out one call site in mouse.c - that can no longer be reached since the error is trapped elsewhere. - -2015-10-24 Ethan A Merritt <merritt@u.washington.edu> - - * src/axis.c (save_autoscaled_ranges restore_autoscaled_ranges) - src/axis.h src/plot2d.c: Auto-scaled axis ranges are extended as data - is read in, but this is counterproductive for some processing modes - (e.g. the y values contributing to 'smooth cnorm'). The new save/restore - routines allow these plot modes to undo the effect of range extension. - -2015-10-22 Ethan A Merritt <merritt@u.washington.edu> - - * src/time.c (gstrptime): Fixes a bug in processing time input using - format "%s". Because time input can cross whitespace between fields, - the string being parsed for one field may continue on into the next - field. The "%s" code looked for the first decimal point in the string, - but would read beyond the current field to find it, causing an erroneous - fractional second to be added to the input time value. - - * term/post.trm: Fix scope of dictionary in Prolog - - * src/term_api.h term/post.trm src/graphics.c (plot_border) - term/PostScript/prologue.ps term/PostScript/prologues.h: - - This change addresses a backward-compatibility issue with the postscript - terminal in version 5. The long ago original postscript terminal used a - double-width line for the plot border. This was what you got when you - specified "lt -1" in a gnuplot command. All terminals agree that lt -1 - is black and solid, but postscript is anomalous in thinking that it has - double width. Furthermore postscript is anomalous in applying the - current line width to draw dots (pointtype 0). This meant that dots - drawn with lt -1 were twice as big as dots drawn with other linetypes. - We could just get rid of the double-width anomaly, but then new plots - would have a thinner border than old plots produced with the same - script. This patch instead adds a layer flag TERM_LAYER_BEGIN_BORDER - so that the postscript terminal can temporarily use a new line type LTB - rather than LTb. All other terminals will ignore it. - Bug #1689 and others - -2015-10-16 Abhijin Adiga <abhijin@users.sf.net> - - * term/lua/gnuplot-tikz.lua: Truncate term->h_char using math.floor(). - This prevents text placement errors on OSX 10.10.2 with lua5.3. - Bug #1682 - -2015-10-16 Ethan A Merritt <merritt@u.washington.edu> - - * term/lua/gnuplot-tikz.lua: lua5.2 deprecates loadstring() in favor of - load().

Converted to Unix - text file format in CVS. - - * config/README: Converted to Unix text file format. - - * config/config.cyg (HAVE_TIME_T_IN_TIME_H): Add this missing - configuration item. - -2004-02-22 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c: When drawing rotated text, only modify pixels - that actually contain part of the text. Fixes bug #668782. Patch - originally submitted by Mike Sutton - <suttonm@users.sourceforge.net>, lightly modified by me. NB: This - code makes refreshing the plot window very slow if rotated text is - present.

Maybe we - could refrain from this requirement in future by adding new field - 'pm3d.on' to 'pm3d.where' in 'struct pm3d'. - -2004-02-15 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c src/plot3d.c src/pm3d.c: Trivial changes to - prevent stupid compiler warnings. - -2004-02-13 Ethan Merritt <merritt@u.washington.edu> - - * demo/prob.dem demo/prob2.dem: pause(-1) after final plot - - * term/svg.trm term/post.trm: Rearrange things slightly so that - the output code is less ugly (cleanup of my 1 Feb 2004 patch). - -2004-02-13 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * config/makefile.nt (makefile.nt, config.h): Copy makefile.nt and - config.nt over into the src directory, if necessary. - - * src/time.c [!USE_SYSTEM_TIME] (gstrptime): Replace - implementation of %s format. Now reads in a double-precision - number and uses gnuplot's own ggmtime() routine instead of library - function gmtime(). This should fix SF bug #885279 "Reading '%s' - timefmt is not 64 bit safe". - (CHECK_SPACE, COPY_STRING, FORMAT_STRING): Macros moved inside - function xstrftime() they belong to. Changed to use do {...} - while(0) pattern. #undef them after use. - (xstrftime): Changed return type to size_t to avoid warnings. - (LETTER, NOTHING): Macros moved into function gstrptime() they - belong to. #undef them after use. - -2004-02-13 Petr Mikulik <mikulik@physics.muni.cz> - - * config/config.os2: Add SELECT_TYPE_ARG* definitions. - -2004-02-12 Ethan Merritt <merritt@u.washington.edu> - - * src/specfun.c demo/random.dem docs/gnuplot.doc: - Modify behaviour of rand() function in response to bug report #870706 - rand(0) returns a pseudorandom number generated from current seeds - rand(-1) resets both seeds to a standard value - rand(x) for x>0 sets both 32-bit seeds to x - rand({x,y}) for x>0 sets seed1 to x and seed2 to y - -2004-02-12 Petr Mikulik <mikulik@physics.muni.cz> - - * src/os2/gclient.c: Let the color sequence of the first 5 line - types be the same as in postscript. - - * src/term.c (do_point): Let sequence of the 6 defined point types - be the same as in postscript, png and x11. - -2004-02-12 Petr Mikulik <mikulik@physics.muni.cz> - - * NEWS src/plot.c src/win/winmain.c src/win/pgnuplot.c - term/win.trm: Let gnuplot on Windows accept the '-persist' command - line option (preferred synonym to '-noend' and '/noend'). - -2004-02-12 Petr Mikulik <mikulik@physics.muni.cz> - - * config/makefile.cyg config/makefile.mgw: Missing copy of file - VERSION into the latexing directory. - -2004-02-01 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.trm term/post.trm term/pdf.trm term/svg.trm: In the rare - case of a request to draw a line or polygon-fill with LT_NODRAW or - LT_BACKGROUND it makes more sense to set the color to white than - to black. The x11 terminal already behaves this way. - -2004-01-25 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.trm docs/gnuplot.doc: Take default font for gdlib - terminals (png jpeg) from environmental variable - GNUPLOT_DEFAULT_GDFONT. - -2004-01-20 Petr Mikulik <mikulik@physics.muni.cz> - - * docs/Makefile.in: gnuplot.tex needs to be latexed 3 times (it - contains multipage toc). - -2004-01-19 Petr Mikulik <mikulik@physics.muni.cz> - - * config/makefile.cyg config/makefile.mgw config/makefile.os2: - Copy file VERSION into the latexing directory (setting TEXINPUTS - from within Makefile does not portably work). - -2004-01-17 Ethan Merritt <merritt@u.washington.edu> - - * src/save.c src/save.h src/show.c: Consolidate the save and show - routines for data and function plot styles into a single place. - -2004-01-14 Lars Hecking <lhecking@nmrc.ucc.ie> - - * Makefile.am: Remove superfluous files from LISP_DISTCLEANFILES. - - * docs/Makefile.in: Add $(top_srcdir) to TEXINPUTS.

Adjust - X11_DRIVER_DIR accordingly. New variable pkglibexec_PROGRAMS for - gnuplot_x11, remove install-exec-local and uninstall-local targets - as automake creates them for pkglibexec_PROGRAMS. - -2004-01-13 Ethan Merritt <merritt@u.washington.edu> - - * src/save.c: The color axis format was not being saved; now it is. - -2004-01-12 Ethan Merritt <merritt@u.washington.edu> - - * demo/webify.pl demo/mgr.pl demo/polar.dem demo/random: - Use 'print' rather than 'pause 0' in demos to avoid empty plots. - Have webify.pl delete empty *.png files on exit. If gpsavediff is - available, use it to create a script for each plot. If gnuplot.css - is present, reference it as a stylesheet. - -2004-01-11 Ethan Merritt <merritt@u.washington.edu> - - * src/command.c, src/term.c, term/x11.trm, docs/gnuplot.doc: - Add sanity checks to 'pause mouse' command; give a warning if mousing - is not active. For X11, do *not* terminate 'pause mouse' on normal - input from stdin. This is necessary to allow 'pause mouse' to work - from piped input since more commands may already be queued up in stdin. - -2004-01-10 Petr Mikulik <mikulik@physics.muni.cz> - - * pm3d.c (geomean4): Support negative values to help splot surfaces with - all color coordinates negative and "set pm3d corners2color geomean". - - * gplt_x11.c: Print the debugging message "gnuplot_x11 3769: mouse - button 1 from window 1 at 0 0" only #ifdef DEBUG. - -2004-01-08 Lars Hecking <lhecking@nmrc.ucc.ie> - - * lisp/configure.in: Remove superfluous file copying commands, now - taken care of by auto* tools. - - * src/gplt_x11.c(pr_window): Bugfix: static array must be computable - at compile time. - -2004-01-07 Ethan Merritt <merritt@u.washington.edu> - - * src/plot.c, term/x11.trm: Set stdin to unbuffered on program entry - rather than waiting for the start of an X11 plot. All buffered input - is lost by the call to setvbuf(), so the only safe time to call it is - before there is any input.

On mouse-capable - terminals the pause will terminate on either a mouse click or on - a <cr>; for all other terminals it is treated as 'pause -1'. - - * src/parse.c src/parse.h: Add a new function get_udv(key) that can - search for user-defined variables even if the key is not a token in - the current command line. - - * src/mouse.c src/command.c: When mousing is active, each mouse click - in the current plot window will update the current value of user-defined - variables MOUSE_BUTTON MOUSE_X MOUSE_Y MOUSE_X2 MOUSE_Y2. In combination - with Jaime Reed's patch below, this allows gnuplot scripts to test for - the presence and result of mouse input. - - * src/gplt_x11.c term/x11.trm: Continue processing mouse activity for - all displayed X11 windows. This is necessarily done in gnuplot_x11, - since gnuplot discards the old scaling information each time it starts - a new plot. The mouse position is updated in the window itself. - There is dummy code in gplt_x11.c that logs mouse clicks to stderr, but - ideally it should be fed to some higher-level process (e.g. Octave). - - * docs/gnuplot.doc demo/mousevariables.dem: Document new mousing - behaviour and provide a sample script that uses it. - -2003-07-22 Jaime Reed <jaime2003@users.sourceforge.net> - - * src/parse.c src/eval.h src/eval.c src/standard.c src/standard.h - src/internal.c src/internal.h configure.in: Create a new builtin - function "defined(<uservar>)" that returns 1 if the user variable - is defined and returns 0 if undefined.

Select at build time by ./configure --enable-isvar - -2003-07-15 Ethan Merritt <merritt@u.washington.edu> - - * src/gp_types.h src/graphics.c src/plot2d.c: Create a new flag - PLOT_STYLE_HAS_BOXES and use this to trigger filled-box processing - rather than testing individually for each plot style that uses it. - - * src/mouse.c: #include "util3d.h" to get prototype for map3d_xy(). - -2003-07-10 Ethan Merritt <merritt@u.washington.edu> - - * term/x11.trm: Gnuplot disables mousing if it thinks the - controlling terminal is not interactive. In this case X11_graphics() - must not attempt to wait for a mouse event during initialization - [Fixes reported bug that first character of input line can be lost]. - -2003-07-07 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c: Detect request for illegal window number and - treat it as window number 0. - - * term/x11.trm: Detect missing font name during "set term x11". - - * src/command.c: Add missing line from what should have been a - patch too trivial for me to mess up (do_string). - -2003-07-07 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/command.c (do_string_replot): Minor simplification: use - gp_strdup() to duplicate current input_line string. Add some - blanks as per CodeStyle document. - (do_string): Likewise. - -2003-07-04 Ethan Merritt <merritt@u.washington.edu> - - * src/command.c: Rewrite do_string() and do_string_replot() so - that no memory corruption occurs if extend_input_line() triggers a - realloc(<xxx>,input_line) during processing. - - * term/x11.trm: Font requests to a remote X-server are very slow; - track font used for most recent text placement and only send a - font request if the current text font is different from the - previous one. - - * src/gplt_x11.c: Collect sequential vector draws into a single - polyline before sending it to the X-server. This makes wide lines - smoother, and gives a small speed improvement for remote displays. - - * src/graphics.c: Replace problematic adjustment of key placement - below plot with a better one. - -2003-07-02 Ethan Merritt <merritt@u.washington.edu> - - * src/mouse.c: DU4.0 cc compiler does not automatically promote - argument of sqrt to (double), so change it to double explicitly. - - * demos/arrowstyle.dem, demos/vector.dem: Show more of what the - `plot with vectors <arrowstyle>` option can do. - -2003-07-02 Petr Mikulik <mikulik@physics.muni.cz> - - * src/pm3d.c (pm3d_reset): Forgotten change of the default value - from 'set pm3d clip1in' to 'set pm3d clip4in' in the patch from - 2002-10-09. - -2003-07-02 Petr Mikulik <mikulik@physics.muni.cz> - - * src/command.c (do_string_replot): Don't allocate so much of the - temporary buffer. - -2003-07-01 Ethan Merritt <merritt@u.washington.edu> - - * src/graphics.c: Make sample arrow in plot key match the arrow - style used by 'plot with vectors'. - -2003-06-30 Ethan Merritt <merritt@u.washington.edu> - - * src/misc.h src/misc.c src/plot2d.c src/set.c docs/gnuplot.doc: - Vector plots are drawn using the linetype in a stored arrowstyle - structure. Make sure this defaults to the linetype for the current - plot #, and that this and the overall plot linetype always agree. - -2003-06-27 Ethan Merritt <merritt@u.washington.edu> - - * src/set.c: Fix unexpected behaviour that 'set grid nox noy' - turned the x and y grids ON rather than off. - -2003-06-26 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * term/dxf.trm (DXF_HTIC, DXF_VTIC): Fixed definitions so 'set - size ratio' can work. - -2003-06-25 Ethan Merritt <merritt@u.washington.edu> - - * src/term_api.h src/command.c term/x11.trm: Define a flag - TERM_INIT_ON_REPLOT by which a terminal driver can request that - term->init() be called at the start of a replot command. - - * src/gplt_x11.c src/mouse.c: Send the current true size of the - x11 display window back from gnuplot_x11 to x11.trm during - term->init().

I have temporarily disabled the - new code while I track down the problem. The offending line is now - protected by #ifdef X11_FONT_UPDATE. - - * term/x11.trm: - Add an interlock so that the gnuplot_x11<->x11.trm font info exchange - is only performed once per splot, rather than every time the view is - changed using the mouse. - -2003-06-19 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c src/graphics.c src/mouse.c src/mousecmn.h term/x11.trm - Use existing mouse communication pipe to send X11 font characteristics - back from gnuplot_x11 to x11.trm. This allows gnuplot to lay out the - plot with v_char and h_char sizes that are correct for the current - default X11 font. This patch slightly changes the timing of initial - operations over the pipe, and adds a FFLUSH(), so there is a remote - possibility that it also fixes a reported problem in which gnuplot_x11 - eats CPU cycles while supposedly idle. This patch should have no effect - if gnuplot is configured with --disable-mouse. - - * term/pslatex.trm: Escape % to %% inside printf() statement. - -2003-06-18 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.h: Fix FPRINTF typo. - -2003-06-16 Petr Mikulik <mikulik@physics.muni.cz> - - * command.c do_string_replot(): Dynamically allocate temporary input - line buffer instead of using a fix-size one.

This fixes a bug where duplicated edges (like the two - sides of the seam in a parametric cylinder) would be completely - invisible. OTOH, it brings back some of the old bleed-through - type of artefacts, because it can't decide which of two copies of - such an edge should be visible. Before this patch it would draw - neither. Now it draws both. - (UINT_BITS, COORD_TO_BITMAXK, CALC_BITRANGE) [TEST_GRIDBOX]: Moved - these macro definitions towards that of type polygon, which they - directly work on. - (COORD_TO_TREECELL) [TEST_QUADTREE]: Likewise, but moved towards - definition of quadtree. - (in_front): Replaced magic number for size of classification by - useful term. - (general) Several functions re-indented to unify code layout - within this module. - -2002-04-05 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/plot2d.c (print_table): Implemented usage of 'set format' - strings by 'set term table' output columns. This has been - documented forever, but never correctly implemented yet. An - earlier attempt was incomplete. Now calls gprintf() to do the - actual work, so gnuplot's extended format specifiers like - '%s*10^{%S}' also work in table output. Also added treatment of - CANDLESTICKS and FINANCEBARS plot styles. - - * src/plot3d.c (print_3dtable): Likewise, except that the 3D case - had been working to some extent, already. But it didn't support - format specifiers other than the standard C ones. - - * src/axis.c (gprintf, mant_exp, decimalsign): Two functions and - one global variable move away from here, into util.c. These used - to be private to the axis module, but are now used by other parts - of the program, too. - - * src/util.h, src/util.c, * src/axis.h: Likewise. - -2002-04-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * docs/gnuplot.doc (set margin): Added a small note about the lack - of effect of margin settings upon 3D plots. - -2002-03-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - Massively edited contribution from Lutz Maibaum: - - * term/post.trm (PS_fillbox) [USE_ULIG_FILLED_BOXES]: Implement - pattern-filling for postscript, too.

This is not very - elegant compared to a possible implementation as a (set of) - PostScript macro(s). - -2002-03-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - Brought in a patch from Stephan Boettcher to add a new command - "set print".

Provides an - second entry point to be used by: - (draw3d_line_unconditional): If v2 is NULL, redirect call to - draw3d_point_unconditional. Moved code before draw3d_line and - flagged it GP_INLINE, to make automatic inlining of this routine - easier for the compilers. - (draw3d_point): Call new routine draw3d_point_unconditional to do - the real work, if hidden3d isn't applicable. - -2002-03-12 Petr Mikulik <mikulik@physics.muni.cz> - - * src/setshow.h src/set.c src/unset.c docs/gnuplot.doc: Added reset - for colorbox and palette.

I.e. now the discrete palette drivers have the - set_color(gray) routine coded like - int gif_color = (int)( gray * sm_palette.colors ); - instead of the previous - int gif_color = (int)( gray * (sm_palette.colors-1) + 0.5 ); - Some other drivers have already this code, so all is unified now. - - * term/post.trm: If 'set palette maxcolors', then the colour for the - last colour box [(colors-1)/colors; 1.0] should equal the last colour - from the mapping formulae, as for the discrete palette drivers. - - * src/win/wgraph.c: Support for 'set palette maxcolors'. - -2001-10-18 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * win/pgnuplot.c (cbGetTextWindow): Revert return value to behave - like the documentation of the EnumThreadWindows() Win32 API call - expects it. - -2001-10-11 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/graph3d.c (boundary) Add code to handle `set size square' or - `set size ratio <number>' for 3D plots, too. Code essentially - copied out of the one found in 2D equivalent function `boundary'. - (boundary3d): Remove stale argument `scaling' and code trying to - use it --- term->scale() was disallowed long ago. - (do_3dplot): Remove local variable `scaling' and code - setting/using it. - - * src/graphics.c (boundary): Remove unused argument 'scaling' - (do_plot): Remove local variable `scaling' which used to be passed - to boundary(), where it wasn't used anyway. - -2001-10-11 Dick Crawford <crawford@arete.com> - - * term/post.trm (PS_header): Old PostScript linewidth patch for - dotted axis linetype finally brought into 3.8 branch.

Use new AUTOSCALE_FIXMIN and - AUTOSCALE_FIXMAX flags instead of a blunt AUTOSCALE_NONE override - to avoid extending the color box beyond the useful z range. - -2001-10-06 Petr Mikulik <mikulik@physics.muni.cz> - - * src/set.c docs/gnuplot.doc: New autoscale option: - `set autoscale keepfix` autoscales all axes while keeping the fix - settings. - - * src/mouse.c: Let hotkey 'a' do `set autoscale keepfix` instead - of `set autoscale`. - -2001-10-05 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/plot3d.c (grid_nongrid_data): Fix bug in code to handle the - case of a sampling point falling exactly onto one of the input - data points, by adding a break statement to bail out of the inner - loop. - -2001-10-05 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/show.c (SHOW_AUTOSCALE): Use new local variable to make code - more readable. Only output " (min)" or " (max)" if they're not - both on. Don't print an extra TAB if non-parametric. Start a new - line occasionally, to make avoid overly long output lines. - - * src/mouse.c (apply_zoom): New static variable autoscale_copies - to remember the state of 'set autoscale'. Zooming overwrites - this, so it has to be recovered at 'unzoom' time. Fill - autoscale_copies upon the initial zoom that leaves 'un-zoomed' - state, and restore it whenever "previous zoom" or "unzoom" - builtins return to the original settings. Resized internal string - buffer to allow for longer mouse-generated command. - (OUTPUT_AUTOSCALE): New macro to help with that task. Visible only - inside apply_zoom(). - (apply_zoom): Save the `set_{min|max}' fields instead of - `{min|max}' for retrieval by "previous zoom" or "unzoom" builtins, - as those represent the user-serviceable parts of the status. - -2001-10-03 Petr Mikulik <mikulik@physics.muni.cz> - - * pm3d/contrib/pm3dConvertToImage.awk: Fix for a too early "stroke" - in converting colour images (replace "/g {stroke" by "/g {Stroke"). - -2001-10-02 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/axis.c (gen_tics): Renamed local variable `ticmin' to - `internal_min', to match its twin `internal_max' in one block. - Don't round internal_{max|min} outwards if ticstep is ridiculously - large. This effectively turned off tic position clipping, and - would lead to coordinate overflow in terminal drivers. - - * term/debug.trm (DEBUG_arrow): Corrected type of argument `head' - to TBOOLEAN. - - * term/gif.trm (GIF_make_palette): Fix incorrect call of debug macro - FPRINTF(). - -2001-10-01 Slaven Rezic <slaven.rezic@berlin.de> - - * term/tkcanvas.trm: No more warnings if running with perl -w. Take - -highlightthickness into account for height/width computation. Use - a subroutine reference rather than a subroutine name in the perl - version (as in my original patch). Doc fix for perl sample. - -2001-09-28 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/graphics.c (plot_c_bars): Changed candlesticks behaviour to - ignore order of high and low prices, as was long since claimed by - the docs, but not actually done in the code. - - * docs/gnuplot.doc: Corrected documentation about candlesticks - behaviour if open and close prices are exchanged.

Uses new static - variables `saved_npoints' and `saved_i' to keep state from one - partial line to the next. - - * term/x11.trm (X11_filled_polygon): Protocol for filled_polygon - call changed. Now uses continuation lines to break up large - polygons like those you get from Petr's filledcurves feature. - Incomplete lines have an "xxxx" at their end; continuations are - flagged by a -1 in the number-of-points field. - -2001-09-19 Petr Mikulik <mikulik@physics.muni.cz> - - * src/win/wcommon.h src/win/wgnuplib.c: New routine - LocalReAllocPtr(). - - * src/win/wgraph.c: Dynamically allocate enough memory for a - polygon with many corners (fixes 'plot with filledcurves'). - -2001-09-19 Alexander Mai <st002279@hrzpub.tu-darmstadt.de> - - * INSTALL docs/gnuplot.doc: Fix old URLs (use gnuplot.org now); - add hyperlinks.

Removed some remains of the old - 'numsolid' stuff. - (Wnd_exec_event): Pass message timestamp to gp_exec_event(), - replacing the fourth input parameter. - (WndGraphProc) [WM_MOUSEMOVE]: Rewrite and uncomment the Cursor - shape call. Also for the section used regardless of 'set mouse - off'. - (WndGraphProc) [WM_CHAR]: moved all the "special" keys into a new - WM_KEYDOWN case --- they don't generate WM_CHAR messages. - (WndGraphProc) [WM_KEYDOWN]: have all keys immediately call - Wnd_exec_event, so the default action can fall through to the - default handler. Handled some open ends introduced by Petr. - (WndGraphProc) [WM_KEYDOWN]: Moved the modifier key status check - to before the individual keys, and translated it from OS/2 to - Windows API.

That's the DLL version, in Win16 - builds. - (LOGPEN) and some others: commented out some definitions no longer - needed, for the MinGW32 build. The compiler's headers no provide - them. - (W_line_width): new message number, for implementing linewidth. - (W_pm3d_setcolor), (W_pm3d_filled_polygon): new message numbers - for PM3D support - - * src/win/winmain.c (MyVFPrintF): New function. vfprintf() was - missing in the simulated <stdio.h> functions of the Windows text - terminal emulation. - - * src/win/wtext.h: comment out 'dontuse_vfprintf', to allow the - new vfprintf() to be used. - - * term/win.trm (WIN_linewidth): new function.

Van Zandt <jrv@vanzandt.mv.com> - - * term/cgm.trm (general): Initialize font table with the standard - WebCGM fonts, plus the Hershey fonts, plus the other fonts - implemented by the Microsoft Office import filter, plus a few - variations (so "oblique" and "italic" are equivalent). Default - font is now "Helvetica Bold". Use a struct array to hold the - standard font names and their relative widths. Add references - to CGM documents, especially those on-line. Defeat assertions - by default. - - * term/cgm.crm (CGM_put_text): Was using the same distance as - the the declared baseline-to-baseline text dimension (used by - gnuplot) and the baseline-to-capline height declared in the - output file. Reducing the character height (by factor of 2/3) - in the output file. Increase default font size from 10 to 12 - pt to compensate. - - * term/cgm (CGM_set_font): Construct the CGM format font list on - the fly. Adjust the declared text width according to the - dimensions of the chosen font. Handle the case where the input - string does not include the font height. - - * term/cgm (CGM_options): If font isn't in table, add it - (retaining the existing fonts). Add "nofontlist" option which - only omits the font list (no effect on color table). - "winword6" is now just a deprecated synonym for "nofontlist". - "solid" option was incorrectly setting cgm_dashed to TRUE. - Fixed. In "linewidth" option, part of sanity check was on - cgm_linewidth instead of cgm_linewidth_pt. Fixed. User can - specify line colors with option like "xff00dd". User colors - go into a separate table, which can grow automatically. - - * term/cgm (CGM_point): Implement open markers. - - * term/cgm (CGM_put_text): Eliminate duplicate elements in output - file: Write text characteristics only if they have changed: font - index, character height, justification mode. Treat character - orientation the same way. - - * term/cgm (CGM_text_angle): generalize internal data - structures to allow for text oriented at other angles than - horizontal or vertical. - - * term/cgm (CGM_linecolor): Eliminate yellow as a line color (too - hard to see against a white background). Add orange and gray. - - * term/cgm (CGM_graphics): For MIL-D-28003A compliance: add - gnuplot version and MIL-D-28003A reference to picture - description, and write element list as the third element. - Omit color table for monochrome file. Add missing elements to - metafile elements list: Color Value Extent, Font List, Color - Table. Add the new elements required for open markers: edge - type, edge width, edge color, and edge visibility. Omit VDC - Integer Precision, Transparency, and Clip Indicator elements, - since some import filter cannot digest them and we are using - the defaults anyway. - - * term/cgm (CGM_linewidth): Flush polylines before changing - linewidth. - - * term/cgm (help text): Document above changes. Add notes - about the Microsoft Office CGM input filter. Rewrap some - paragraphs to stay within the specified 73 columns. - -2000-10-06 Johannes Zellner <johannes@zellner.org> - - * implemented finally configurable offsets for - set label "xy" at x, y pointsize 1 offset 2.0, 3.0 - Useful for placing labels slightly offset from data - points.

When keys are - typeset, then new global global variable `ignore_enhanced_text` is set. - Then enhanced terminals decide whether to use normal-text or - enhanced-text writing method. - Note: There was another method proposed to solve this problem: all - escape characters to be backslashed on reading of the title. However, - this would not work if the same plot is replotted subsequently on - enhanced and non-enhanced terminals. - -2000-07-13 Petr Mikulik <mikulik@physics.muni.cz> - - * pm3d: src/os2/gclient.c, term/pm.trm: bugfix for color palette - allocation ('set palette maxcolors' was ignored). - -2000-07-10 Petr Mikulik <mikulik@physics.muni.cz> - - * src/color.c: boundary around the color box is drawn by move&line - for bitmap as well as postscript-including terminals. - Contributed by Gregor Thalhammer <Gregor.Thalhammer@uibk.ac.at>. - -2000-06-24 Petr Mikulik <mikulik@physics.muni.cz> - - * src/color.c: if is_log_z, then print the non-logged values of z_min - and z_max around the color box. - - * src/unset.c: 'unset pm3d' sets the y axis to noreversed if the - reversed has been set by 'set pm3d map'. - - * pm3d: a trick for rotating the ylabel via 'set pm3d map' (see - variable `pm3d_map_rotate_ylabel`). That's needed because gnuplot - does not have an option for rotating x,y,z axes labels; once it - possesses it, the above mentioned variable would be replaced by the - new one. - -2000-07-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * all over the place: restructured axis module global - variables. Instead of sevaral separate arrays, it's now - a single array of structs, to bring it even closer to the - idea of an OO-style axis class. - * removed some more occurances of 'extern' from .trm and - .c files.

So don't use 3 as - a test case. - -2006-04-05 Ethan A Merritt <merritt@u.washington.edu> - - * term/svg.trm: New line-join terminal option {rounded|butt}, - with support for smooth joining of closed polygons via the recently - added newpath()/closepath() mechanism. - - * src/gadgets.c (draw_clip_arrow): Provide a routine in the core - code that clips arrow head/tail to the canvas boundaries. This means - we don't have to do the clipping in do_arrow(), which has been messy. - - * src/graph3d.c (plot_arrows3d plot3d_vectors) - src/graphics.c (place_arrows do_key_sample get_arrow) - Draw arrows using new routine draw_clip_arrow. - Addresses bug #1348015 and others. - - * src/term.c (do_arrow): Add a note that the clipping here is now - redundant, and can be removed.

This seems - necessary in order to handle en_US.UTF-8 and similar locales, which - claim to require many exotic but trivial charsets. Normally these are - not needed, so it should not be a fatal error if they are missing. - Bug #1458525 - - * term/x11.trm: Increase maximum allowed length of font names. - -2006-04-04 Ethan A Merritt <merritt@u.washington.edu> - - * misc.c (lp_use_properties lp_parse): In "set style increment user" - mode, an explicit linetype should be interpreted as a call for the - corresponding line style. But if there is none, we should load a - description of the linetype rather than failing to initialize the - lp_style_type at all. - -2006-03-28 Lars Hecking <lhecking@users.sourceforge.net> - - * docs/gnuplot.texi: Regenerated after recent documentation - updates. - - * term/Makefile.am.in: Add PostScript directory to EXTRA_DIST.

This - removes a large chunk of text from the postscript driver, and allows - local customization, editing, or patching of the postscript - configuration. The directory in which these files are stored is taken - from config.h: #define GNUPLOT_PS_DIR - but may be replaced at runtime by an environmental variable of the same - name, or by a "set loadpath" command inside gnuplot. - This change should result in no change to the postscript files output - by gnuplot. - -2006-03-24 Ethan A Merritt <merritt@u.washington.edu> - - * src/datafile.h src/datafile.c: Allow an input field expected to be - a time format to be in quotes.

No actual change - in behavior, but it quiets valgrind warning messages. - - * term/post.trm: Prevent segfault if someone passes off an undefined - variable as an epslatex header. This is a bandaid rather than a true - fix, but it's better than segfaulting. The true problem is that an - int_error() exit from expression parsing bypasses proper cleanup of - storage for string variables, and also fails to return NULL to the - caller.

This eliminates some 'extern's in C files and moves - code specific to pm terminal to pm.trm. - 1. Remove update_menu_items_PM_terminal() from mouse.c. - 2. Rename send_gpPMmenu() in mouse.c to PM_set_gpPMmenu() and move the - actual communication with gnupmdrv to new routine - PM_update_menu_items() in pm.trm. - PM_set_gpPMmenu() now only updates the gpPMmenu struct. - 3.

The old behaviour was to issue an error - and bail to the command line. df_open() now returns a negative number - if the requested file cannot be opened. Callers must test for error - return. - - * src/plot2d.c (eval_plots): If a requested file is missing or empty, - create an empty plot structure for it, but plot other functions or - datafiles as usual.

This reverts the epslatex driver to - the old behaviour of ignoring any distinction between "front" and - "back" text labels. It also clears the deck for a different - approach that adds a terminal API routine to handle this sort of - terminal-specific requirement (SourceForge patchset #1191202). - -2005-07-11 Ethan Merritt <merritt@u.washington.edu> - - * src/breaders.h src/datafile.c src/datafile.h src/fit.c src/plot2d.c - src/plot3d.c src/set.c: Simplify conditional compilation controlled by - --enable-binary-data-file. Instead of having a different number of - parameters to df_readline() and plot_option_binary(), expost a uniform - definition but add an auxilliary routine df_set_plot_mode() in the - BINARY_DATA_FILE case.

The addition of pm3d code to 2D plots began in portions - of the WITH_IMAGE patch; remove the dependence on WITH_IMAGE to prepare - for more general use of pm3d colorspecs in 2D plots. - Introduce general checking for pm3d colorspecs in 2D plots. This fixes - a bug that the colorbox could only be drawn for "with image" plots if - the *first* plot used pm3d; subsequent plots were not checked. - Also, pm3d colorspecs were already usable for text coloring in 2D, but - no colorbox was drawn if they were used.

Also, removed language indicating gnuplot matrix - binary is restricted to `splot`, as it now can be used for images in - `plot`. - - * src/Makefile.am: Added gplt_x11.h to gnuplot_SOURCES list and - gnuplot_x11_SOURCES list. Added bin_hook.c to gnuplot_SOURCES list and - removed binary.c and binary.h from this list. - - * src/README: Added a discussion of technical details about how the - formulas for properly orienting an image and passing that to the - terminal driver are derived. They can be arcane if just looking at the - code inside plot_image_or_update_axes(). Same goes for the details - about sending binary data to gnuplot_x11 for images. It requires a - simple heuristic encoding scheme to avoid a few particular characters - from the data stream and can appear confusing at first sight. - - * src/bin_hook.c: A new, short file to include binary.c in the source - tree if BINARY_DATA_FILE is not defined. Otherwise, binary.c is no - longer required. - - * src/breaders.h: An example of how to read a header in a particular - file format and fill in the general binary structure details. Not - completely sure just yet how this should be integrated into gnuplot. - - * src/color.c (draw_color_smooth_box): Added an option for `plot` mode - for use in images with a palette. - - * src/color.h: Adjusted function definition for change noted above. - - * src/command.c: Now save a new property is_cb_plot to determine if a - color box can be part of the plot in question. - - * src/command.h: Added declaration of is_cb_plot variable. - - * src/datafile.c: Extensive additional code for interpreting general - binary keyword syntax. Changed df_readline() to df_readascii() and - added a new file df_readbinary() analogous to df_readascii(). A new - df_readline() chooses which of these two to utilize. Code for reading - binary and ASCII matrix format file was moved to df_readbinary(). This - means other files in the source tree could be restructured so that the - routine df_readline() is the only method to bring data into gnuplot. - - * src/datafile.h: Declarations for new functions as part of code noted - above. Also, there are a few new enumerations and, most importantly, - the definition for the structure containing information about general - binary records. - - * src/fit.c (fit_command): Altered df_open() argument to include the - plot mode MODE_QUERY. - - * src/getcolor.c: Reactivated rgb255_from_gray(), required for images. - - * src/gp_types.h: Added IMAGE and RGBIMAGE to PLOT_STYLE enumeration. - - * src/gplt_x11.c: Extensive additional code for handling images in - binary data format, polygons in binary data format, and an endianess - check to determine if bytes need be swapped. A simple, short encoding - scheme is used for binary data to avoid a couple special characters in - the data stream. - - * src/gplt_x11.h: A new header file to go along with gplt_x11.h - containing definitions for code characters sent across pipe. Also some - definitions for translation characters in the binary encoding scheme. - - * src/graph3d.c (do_3dplot): Added a plot_mode of MODE_SPLOT to - argument of draw_color_smooth_box(), as now that can also be done for - `plot`. Also, added cases of IMAGE and RGBIMAGE to plot style switch. - - * src/graphics.c: Added plot_image_or_update_axes(), a new image - plotting routine. The new routine is fairly long and arcane in spots. - The README file contains details to clear up obscure parts. Added the - cases IMAGE and RGBIMAGE to the switch statement for plot style. Also, - there is code for making room for a color box on the plot, followed by - a call to draw_color_smooth_box() where appropriate. - - * src/graphics.h: Added definitions PLOT_IMAGE(), SPLOT_IMAGE() and - UPDATE_AXES_FOR_PLOT_IMAGE() to make plot_image_or_update_axes() seem - more intuitive. - - * src/misc.c: Added 'image' and 'rgbimage' to list of plot styles in - error message indicating valid styles. - - * src/mouse.c (builtin_toggle_log): For plots having a color box - property, allow changing the color box to logarithmic scale. - - * src/plot2d.c: Many small alterations to case statements, etc. to - integrate IMAGE and RGBIMAGE plot styles. Also, added MODE_PLOT to - df_open() argument list for binary data files. - - * src/plot3d.c: Similar to plot2d.c, many little changes made to - incorporate IMAGE and RGBIMAGE plot styles. Also, for general binary - there is no longer need for df_3dmatrix(), so that call was removed. - Added MODE_SPLOT to argument list of df_open(). - - * src/save.c (save_data_func_style): Write `image` or `rgbimage` to - file if appropriate plot style. - - * src/set.c (set_command/set_palette_file): Added call to routine - setting defaults for binary data files if `binary` is specified as - part of `set` command. / Added MODE_QUERY to list of arguments for - df_open(). - - * src/show.c (show_datafile): Now show information about binary data - file settings and details about binary variable sizes in bytes for the - compiler under which gnuplot was built. - - * src/tables.c (show_style_tbl): Added `image` and `rgbimage` to table. - - * src/term_api.h (TERMENTRY): Added image() prototype function to - TERMENTRY structure as well as an enumeration for image type as an - argument to image() routine. - - * src/unset.c (unset_command/reset_command): Added call to routine that - clears the binary data file record information. - - * src/util3d.c: Added a routine map3d_xy_double() to retain more - accurate coordinates necessary for checking uniformity of the image - grid via hyperplane concepts. It is repetition of existing code, - but there is a note and define switch for code-reuse. - - * src/util3d.h: Added declaration for map3d_xy_double(). - - * term/README: Added note about how to properly use image() terminal - function. - - * term/aquaterm.trm: Per Persson added an implementation of the image() - terminal function, AQUA_image(). - - * term/dumb.trm: Ethan Merritt added a space filler for the image() - terminal function location of TERM_TABLE. - - * term/epslatex.term: Added PS_image() to structure for image() in - TERM_TABLE. PS_image() is in post.trm. - - * term/gd.trm: Ethan Merritt added a routine PNG_image() for the - TERM_TABLE entry of image(). Also, a supporting routine PNG_set_color - was created. - - * term/pdf.trm: Ethan Merritt added a routine PDF_image() and entry - into the TERM_TABLE for image support for PDF files. - - * term/post.trm: Added a routine PS_image() and appropriate entry in - the TERM_TABLE for image support in PostScript files. There is also a - supporting routine PS_encode85() for encoding binary image data in - ASCII85 data format. - - * term/pslatex.trm: Added PSLATEX_image() to structure for image() in - TERM_TABLE. It uses a simple call to PS_image(), which is in post.trm. - - * term/svg.trm: Added space filler in TERM_TABLE for image() function. - - * term/x11.trm: Added X11_image() function and entry in TERM_TABLE. - The new image routine contains code for a simple, heuristic encoding - scheme to prevent a couple specific bytes from being in the image data - stream. Similarly, X11_filled_polygon() and X11_set_color() were - altered to use the same scheme to reduce the amount of characters - inside the plot buffer. - -2004-08-27 Per Persson <persquare@mac.com> - - * src/term.c (init_terminal): Make aqua the default terminal on - Mac OS X if AquaTerm is installed. - -2004-08-27 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.trm (PNG_vector): More specific test for libgd support of - antialiasing.

Reindentations. - - * src/fit.c (log_axis_restriction): New function to output the - actual state of the axis ranges, as optionally modified by range - specified in the fit command line. - (fit_command): Use it. - - * src/graphics.c (plot_bars): Reindentation. - - * src/util.c (mant_exp): Reindentation. - - * src/plot3d.c (print_3dtable): #undef OUTPUT_NUMBER earlier. - -2004-06-24 Ethan Merritt <merritt@u.washington.edu> - - * src/mouse.c (event_reset): If 'pause mouse' terminates because - the plot window is closed, insert an extra '\n' into the input - stream so that the first character of the subsequent command is - not swallowed. - -2004-06-20 Ethan Merritt <merritt@u.washington.edu> - - * src/mouse.c (event_reset), src/command.c (pause_command), - docs/gnuplot.doc: Set MOUSE_KEY to -1 when the "pause mouse {key}" - command is issued; if it is still -1 when checked later, then the - calling program may assume that no mouse input was successfully - given. - - * src/command.c (pause_command): Change the test for legality of - "pause mouse" command from "if (term_initialised)" to "if - (mouse_setting.on)". Really it should test whether the current - terminal supports mousing at all, but we don't yet have such a - flag. - - * src/gplt_x11.c (process_event): Translate keystrokes using - XLookupString() rather than XKeycodeToKeysym(). This method - handles characters produced using shift, alt, or other multi-key - sequences. - - * src/graphics.c (plot_f_bars plot_c_bars), term/gd.trm - PNG_options): Make sure that the tic size is greater than zero. - -2004-06-20 Petr Mikulik <mikulik@physics.muni.cz> - - * src/graph3d.c (key_sample_line_pm3d key_sample_point_pm3d): - Fixed wrong step for negative palette. - - * src/color.c (set_color) src/command.c (test_palette_subcommand) - src/show.c (show_palette_palette): Removed useless comments. - -2004-06-19 Petr Mikulik <mikulik@physics.muni.cz> - - * src/color.c (set_color, draw_inside_color_smooth_box_bitmap) - src/pm3d.c (cb2gray): Invert gray in routine pm3d.c:cb2gray(cb), - instead of color.c:set_color(gray). The latter is now just setting - term->set_color(gray) if the terminal supports set_color() API. - - * graph3d.c (do_3dplot): Fixed set_color(z2cb( cb2gray(cntrs->z)) - to set_color(cb2gray( z2cb(cntrs->z) )). - - * gadgets.c (apply_textcolor): Take care of positive/negative - palette for 'set label ... textcolor frac ...'. - -2004-06-17 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c (process_event): Send a GE_reset event back to gnuplot - if the current plot window is closed. - * src/mouse.c (event_reset): Terminate paused_for_mouse state whenever a - GE_reset event is received. - -2004-06-16 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c (mainloop): Yet another tweak to the mouse timing code. - This one reduces mouse-tracking hysteresis on systems that claim to have - usleep() but in fact have much coarser timing. - -2004-06-16 Petr Mikulik <mikulik@physics.muni.cz> - - * src/save.c: Save log cb axis (bugfix). - -2004-06-14 Petr Mikulik <mikulik@physics.muni.cz> - - * src/mouse.c: Do not start zooming during 'pause mouse'. - -2004-06-12 Ethan Merritt <merritt@u.washington.edu> - - * show.c (show_datafile): Provide missing show commands for suboptions - "show datafile {separator|comment|missing}". - -2004-06-12 Ethan Merritt <merritt@u.washington.edu> - - * datafile.h: define DF_MISSING as a return code from df_readline(). - * datatile.c (df_readline): If a data field contains the missing data - string, return DF_MISSING rather than DF_UNDEFINED. - * fit.c (fit_command): Explicitly ignore DF_MISSING data. - * plot2d.c (get_data): Explicitly test for data marked DF_MISSING - but treat it the same as DF_UNDEFINED. - * plot3d.c (get_3ddata): Explicitly test for data marked DF_MISSING - but treat it the same as DF_UNDEFINED. - - These are trivial changes that do not affect the existing behavior of - gnuplot. However, the core routines in plot2d and plot3d now have the - information needed to treat missing data differently depending on the - plot style if desired. - -2004-06-06 Ethan Merritt <merritt@u.washington.edu> - - * src/command.c src/command.h src/mouse.c src/gplt_x11.c - term/x11.trm docs/gnuplot.doc docs/gnuplot.texi: - `pause mouse keypress` option behaves exactly as `pause mouse` except - that the pause can be terminated by a keystroke while the plot window - has focus. On return, the variable MOUSE_KEY contains the mouse button - number if the pause terminated on a mouse click, otherwise it contains - the key code of the key that was pressed. Normal ascii characters will - return their ascii code; other keyboard keys are assigned codes from a - table in mousecmn.h. The command may be shortened to `pause mouse key`. - -2004-06-04 Petr Mikulik <mikulik@physics.muni.cz> - - * src/mouse.h src/mousecmn.h src/mouse.c: Split array special_keys[] of - of key names and key codes into special_keys[] and usual_special_keys[], - so that "usual" keys (like BackSpace, Tab, Enter, Return, Escape, Tab, - Delete) can have their "usual" keycodes instead of those >=1000. - Changed lookup_key() and bind_fmt_lhs() in mouse.c to look into both - arrays. This does not change any functionality of the current version - of gnuplot, but will help new future features (like "pause mouse key"). - -2004-06-03 Ethan Merritt <merritt@u.washington.edu> - - * term/emf.trm (EMF_linewidth): Force re-evaluation of line - characteristics when the linewidth changes; otherwise the new width - is ignored until some other property changes as well. - -2004-06-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * demo/fillcrvs.dem: Add text to pause -1 prompts. - - * docs/gnuplot.doc (plot datafile using): Document restrictions of - 'using' format-strings. - - * src/datafile.c (valid_format): Check that there's at least one - actual %lf format in the format string, and no more than 7, - because the scanf() that uses the format supplies only 7 arguments - to store data in. - (plot_option_using): Change error message to reflect new status - output of valid_format(). - -2004-05-28 Petr Mikulik <mikulik@physics.muni.cz> - - * src/getcolor.c (color_components_from_gray): Test gray value for - being in range [0;1]. - -2004-05-27 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c (PaletteSetColor): Test for overflow of index - derived from color ramp calculation. Is this algorithm really correct? - -2004-05-27 Petr Mikulik <mikulik@physics.muni.cz> - - * term/post.trm (PS_make_header): Change definition of /pm3dround - to fix color mapping with 'set palette maxcolors'. - - * src/win/wgraph.c (drawgraph): Change call from rgb255_from_gray() to - rgb255maxcolors_from_gray().

Change it to (int) everywhere. - -2004-05-24 Petr Mikulik <mikulik@physics.muni.cz> - - * src/pm3d.c src/term.c term/hpljii.trm: SF bug #953887 non-portable C - code (prototypes & TBOOLEAN): input parameter for routines cannot be - char, they must be int. - -2004-05-21 Ethan Merritt <merritt@u.washington.edu> - - * src/gplt_x11.c (mainloop): Add a 100 usec delay to the event flush - loop, so that if the other end of the pipe is jammed (gnuplot STOPPED) - it doesn't monopolize CPU cycles. Fixes user-triggered error condition - reported in bug #930426. - -2004-05-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de> - - * src/graphics.c (plot_boxes): Clip lower border of - boxxyerrorbars, too. - (do_plot): Regrouped master switch over plot types. Draw box - first in BOXERROR mode, to keep the lower part of the errorbar - visible. - - * src/util.c (mant_exp): Extend technique for rounding exponents - depending on the printf format precison of the mantissa to format - specifiers %l and %L used for log bases other than 10.

Therefore - [xmax,ymax] is out of range, and we should revise the clipping limits - accordingly. NB: This may change the behavior of existing scripts that - draw to the extreme edge of the canvas (e.g. border=0). - Bugfix: Prevents tripping the assert() statements in emf.trm - -2008-06-24 Bastian Maerkisch <bmaerkisch@web.de> - - * src/win/wgraph.c (drawgraph): Don't forget to draw a polyline even - if it has only a single segment. - Bugfix - -2008-06-23 Petr Mikulik <mikulik@physics.muni.cz> - - * src/color.c (draw_inside_color_smooth_box_postscript): Fix colour of - the 2nd box in the colour box for negative palette in postscript - output. - SF Bug #2000751 - -2008-06-22 Ethan Merritt <merritt@u.washington.edu> - - * src/plot2d.c: Plot with vectors did not honor linestyles requested via - 'set style increment user'. - -2008-06-20 Ethan Merritt <merritt@u.washington.edu> - - * src/set.c (delete_linestyle) src/unset.c src/setshow.h: - Pass the head of the linestyle list as a parameter rather than - hardcoding it to always be the list headed by first_linestyle. - Remove unused routine assign_linestyle_tag(). - - * src/misc.c src/misc.h src/term.c (lp_use_property): - Move this routine from misc.c to term.c. This cleans up a botched - header dependency (the prototype was already in term_api.h rather than - being in misc.h). - -2008-06-19 Ethan Merritt <merritt@u.washington.edu> - - * term/aquaterm.trm (AQUA_init AQUA_boxfill AQUA_filled_polygon): - Query aquaterm for alpha channel support; use it if present. - Add fill styles to the filled polygon routine. - -2008-06-18 Ethan Merritt <merritt@u.washington.edu> - - * src/fit.c: Dynamic allocation for fit script string. - -2008-06-17 Ethan Merritt <merritt@u.washington.edu> - - * docs/gnuplot.doc docs/plotstyles.gnu demo/cities.dat: - Revise the plot style examples to avoid pattern fill since pdfcairo is - bad at it. Use a more interesting demo to illustrate label plots. - -2008-06-15 Ethan Merritt <merritt@u.washington.edu> - - * src/wxterminal/wxt_gui.cpp: - Remove deprecated dc.BeginDrawing() dc.EndDrawing() - -2008-06-14 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de> - - * src/datafile.h (df_no_fpe_trap, evaluate_inside_using): Add - missing 'extern' to declaration of new variables. - -2008-06-13 Ethan Merritt <merritt@u.washington.edu> - - * docs/gnuplot.doc docs/titlepag.tex docs/gnuplot.texi: - Replace "what's new in 4.0, 4.2" with "what's new in 4.3". - Remove discussion of pre-version 4 features. - Update or remove dead URLS. - -2008-06-12 Ethan Merritt <merritt@u.washington.edu> - - * src/datafile.c src/datafile.h src/set.c src/save.c src/show.c - eval.c (evaluate_at) docs/gnuplot.doc: - New datafile property 'set datafile {no}fpe_trap'. - - Until now, evaluate_at() has wrapped every expression evaluation with - set/reset of a floating point exception handler. This is very expensive - and dramatically slows down data input from large files. Now we provide - a way to disable this via "set datafile {no}fpe_trap" or turn it back on - again if necessary. The exception handler remains in place for contexts - other than data input. - -2008-06-08 Ethan Merritt <merritt@u.washington.edu> - - * src/graphics.c src/misc.c src/save.c src/show.c src/unset.c: - The flag LT_UNDEFINED was mis-used to indicate "same color as fill" for - the border of filled areas. This caused hard-to-reproduce bugs in the - key samples for plots with filled areas. Change the fillstyle code to - use LT_DEFAULT instead for this purpose. - -2008-06-07 Ethan Merritt <merritt@u.washington.edu> - - * src/set.c (set_margin) src/save.c (save_set_all) docs/gnuplot.doc - demo/margins.dem demo/transparent_solids.dem demo/rgbalpha.dem: - Add a new keyword "at" to absolute margin placement commands. - 'set rmargin screen .8' misleadingly seems to assign 80% of the page - to the right margin. Really we mean "set rmargin at screen 0.8", - so say that. - -2008-06-05 Ethan Merritt <merritt@u.washington.edu> - - * src/axis.c (gen_tics): Interpret tic labels read from a data file as - string constants rather than as formats. Otherwise there are problems - with labels containing the "%" character. - -2008-06-05 Petr Mikulik <mikulik@physics.muni.cz> - - * src/mouse.c (builtin_toggle_log): Help line for the 'l' hotkey missed - to mention both z and cb for splots. - -2008-06-04 Ethan Merritt <merritt@u.washington.edu> - - * src/mouse.c (builtin_nearest_log): - Further adjustment to 'L' hotkey behavior. In "set view map" mode, - toggle the cb axis if the cursor is in the color box, toggle the x1 axis - if it is nearest, the y1 axis if it is nearest, and the z axis if none - of the above conditions is true. - - * demo/heatmaps.dem: Modify the last demo so that it can be used to - explore the behavior of the 'l' and 'L' hotkeys. All 4 axes (x y z cb) - can be individually toggled using the 'L' hotkey. 'l' toggles only y, - which is what the documentation says, but maybe this should be changed. - - * src/graph3d.c: Allow to draw contours associated with a pm3d surface. - -2008-06-02 Ethan Merritt <merritt@u.washington.edu> - - * src/hidden3d.c (store_polygon) src/mouse.c (event_motion): - Replace a pair of assert() statements with a flag that prevents mouse - interaction from further increasing the value of surface_zscale. This - means you cannot trigger the error condition the asserts tried to guard - against just by moving the mouse. You can still trigger it by setting - the view parameters to something odd, but the patch of 2008-05-29 may - handle that. - Bug #172806 - - * src/term.c (estimate_strlen) term/estimate.trm: - Allow for embedded newlines when estimating string length and height. - - * src/graphics.h src/graphics.c src/gadgets.h src/graph3d.c src/color.c - src/mouse.c: Move the bounding box information for the key and for the - colorbox into their respective structures so that they can be shared by - 2D and 3D code. Change the 'l' and 'L' hotkeys so that the color axis - log scaling is toggled if and only if the mouse is in the colorbox. - -2008-06-02 Shigeharu Takeno <shige@iee.niit.ac.jp> - - * docs/term-ja.diff docs/gnuplot-ja.doc: - Sync Japanese documentation to gnuplot.doc revision 1.506 - -2008-06-02 Tim Hoffmann <t_hoffmann@users.sourceforge.net> - - * src/win/wtext.c (WndParentProc): Account for scrollbars when shrinking - the textwin to the maximally needed width.

This broke mouse zooming and replot. - - This patchset is an imperfect fix with several known problems: - - Clipping of zoomed 3D contour plots is not correct. - - splot volatile with image + zoom + unzoom is flaky - - plot -> zoom -> set grid -> unzoom loses the grid setting. - - you cannot toggle log scaling on/off while using refresh. - - Introduce a new command "refresh" that acts like replot except that it - does not re-read the input data. Refresh is always needed in order to - zoom or replot in-line data (input file '-'), but may optionally applied - to normal data files also by appending the attribute 'volatile'. - - * src/plot2d.c (eval_plots): This is the core change. Instead of - freeing stored data after each plot, keep it around in case of a - refresh command. The old data storage is freed at the start of the next - "plot" or "replot" command. This is parallel to what the 3D code was - already doing.

But if called on exit, the pipe to gnuplot_x11 may - already be closed. Don't try to write to it. Bug #1706945. - -2007-04-19 Ethan Merritt <merritt@u.washington.edu> - - * docs/gnuplot.doc: Fix unterminated quote that causes emacs/makeinfo - to fail. - -2007-04-17 Ethan Merritt <merritt@u.washington.edu> - - * configure.in: Fix spelling of BACKWARDS_COMPATIBLE yet again. - -2007-04-17 Ethan Merritt <merritt@u.washington.edu> - - * term/post.trm: Change the default to "blacktext" for the TeX-based - terminal variants (pstex pslatex epslatex). This is more in line with - the behaviour in versions 4.0 and earlier. In particular it means that - the default settings do not require you to include the color.sty - package. - -2007-04-17 Andrej Lajovic <natrij@users.sourceforge.net> - - * src/save.c (save_set_all): Save all key options even if - key is not currently displayed. - Bug #1695643 - -2007-04-17 Daniel Sebald <daniel.sebald@ieee.org> - - * src/graphics.c (plot_vectors): - Fix access of uninitialized variable found by valgrind. - -2007-04-14 James R.

This is a - bug-fix for spurious 0-width lines that appear when a cairo-based - terminal is used to generate pdf files, this bug does not appear in - wxt. - - * src/wxterminal/gp_cairo.c: Fix and complete debugging messages. - -2007-03-21 Daniel Sebald <daniel.sebald@ieee.org> - - * src/graphics.c (boundary): The change of 2007-02-25 overlooked the - 2D plots having palettes that also required setup_tics(COLOR_AXIS,). - Bug #1684789 - -2007-03-16 Bastian Maerkisch <bmaerkisch@web.de> - - * src/win/winmain.c (appdata_directory): Prevent segfault if no - directory is given and the environmental variable APPDATA is not set. - -2007-03-14 Ethan Merritt <merritt@u.washington.edu> - - * src/graph3d.c (draw_3d_graphbox): Fix bug that caused axis labels - not to be drawn in 'set view map' mode. - -2007-03-13 Timothee Lecomte <timothee.lecomte@ens.fr> - - * demo/transparent.dem: Add messages to 'pause -1' commands to avoid - guessing that gnuplot is taking a lot of time to plot while it is just - waiting for user input. - -2007-03-11 Timothee Lecomte <timothee.lecomte@ens.fr> - - * configure.in: - * INSTALL: - Report mouse support in the features section, not as an option of the - x11 terminal, since it is in fact true for other interactive terminals - such as wxt or vgagl. - -2007-03-08 Ethan Merritt <merritt@u.washington.edu> - - * src/datafile.c (df_readline df_generate_pseudodata df_open df_gets): - Implement a function-plotting mode that allows 'using' options. - '+' is a pseudo-file that in 2D plots returns a stream of <samples> - values corresponding to x coordinates within the current xrange, - In 3D plots it returns a stream of x and y coordinates on the - <isosamples> grid. In either case, additional columns of data can - be attached the x and y coordinates via a 'using' specification, - just as for real data files. - - * demo/4D-data.dem demo/all.dem demo/approximate.dem demo/html/Makefile - docs/gnuplot.doc: Demos and documentation. - -2007-03-07 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.trm (PNG_init_brush): Cleaner fix for Bug #1673316. - Consolidate duplicated code surrounding calls to PNG_init_brush() into - a single copy in the subroutine itself. - -2007-03-06 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.trm (PNG_init_brush): Flag initial color as invalid.

This patch forces the width to be an odd - number of pixels so that the box is symmetric. Also, honor the border - linetype of the current fillstyle. - -2007-03-03 Ethan Merritt <merritt@u.washington.edu> - - * docs/titlepag.tex: Update author list and copyright information. - - * NEWS: Update - - * demo/pm3d.dem: Add "test palette" to the demo series. - -2007-02-28 Ethan Merritt <merritt@u.washington.edu> - - * term/gd.trm (PNG_image): libgd is sensitive to the order of the bounds - used for clipping.

It was supposedly - doing this already. Now it really does. - -2007-02-25 Petr Mikulik <mikulik@physics.muni.cz> - - * src/color.c (draw_color_smooth_box) src/plot3d.c (eval_3dplots): - Call setup_tics(COLOR_AXIS, 20) at the same place as setup_tics(...) - for all other axes. Until now it was called much later during color box - drawing where it could change the colour axis min or max by rounding it - to lower/upper tics step. - -2007-02-23 Ethan Merritt <merritt@u.washington.edu> - - * src/datafile.h src/datafile.c (df_reset_after_error) - src/util.c (int_error): The routines in datafile.c use local variables - to track the context of expression evaluation; e.g. expressions may - only reference data column values inside a `using` statement. But the - state of these context variables is corrupted if an error exit bails - directly to the command line, thus bypassing the normal execution path. - Therefore we provide a routine df_reset_after_error() to be called - from int_error(). FIXME: Similar error_reset routines may be needed - by other modules. - - * src/eval.c docs/gnuplot.doc: Allow "strcol(foo)" as shorthand form - of "stringcolumn(foo)". - - * src/unset.c (unset_style) src/set.c (set_nolinestyle): - Add missing command "unset style line <n>". - -2007-02-22 Mojca Miklavec <mojca.miklavec.lists@gmail.com> - - * term/latex.trm (LATEX_fillbox): Add support for solid-fill boxes. - EAM: style parameter accepted, but density and fill patterns are limited - to solid white or solid black. - -2007-02-22 sobukus@users.sourceforge.net - - * m4/apha.m4: Fix syntax of test for gcc on alpha - -2006-02-21 Shigeharu Takeno <shige@iee.niit.ac.jp> - - * docs/gnuplot-ja.doc docs/term-ja.diff: Sync Japanese documentation. - -2007-02-21 Ethan Merritt <merritt@u.washington.edu> - - * src/term_api.h: Define S_ENC_UTF8 for completeness (used by gd.trm if - libgd.2.0.34 is found) even though no user command exists yet to set it. - - * term/metapost.trm: Set flag TERM_CAN_CLIP, so that the clipping - (or rather lack of clipping) is like other postscript variants. - -2007-02-18 Ethan Merritt <merritt@u.washington.edu> - - * demo/image2.dem demo/image.dem demo/macros.dem demo/rainbow.dem - demo/rectangle.dem: Change version test to look for 4.3 rather than 4.1 - -2007-02-18 Petr Mikulik <mikulik@physics.muni.cz> - - * src/pm3d.c (pm3d_plot): Use the z-averaging also for flushed - triangles. - -2007-02-17 Petr Mikulik <mikulik@physics.muni.cz> - - * docs/gnuplot.doc: Updates in dgrid3d and contours sections. - -2007-02-14 Ethan Merritt <merritt@u.washington.edu> - - * docs/gnuplot.doc docs/gnuplot.texi: Fix typos that cause TeX failure. - - * tutorial/header.tex: Add \usepackage{amssymb} - -2007-02-13 Daniel Sebald <daniel.sebald@ieee.org> - - * src/graph3d.c (boundary3d): Move addition of title key title lines to - number key_rows outside conditional test. - -2007-02-13 Ethan Merritt <merritt@u.washington.edu> - - * src/graphics.c (boundary): Do not apply log scale range checks to - colorbar and palette unless these really are used in the plot. - Bug #1659059 - - * docs/gnuplot.doc: Clarify the section on 'set log', and remove an - empty entry point for 'set log cb'. - -2007-02-11 Petr Mikulik <mikulik@physics.muni.cz> - - * src/command.c (pause_command): On Windows, cannot wait for Enter - in "pause -1" in a non-interactive session without the graph window. - -2006-02-10 Shigeharu Takeno <shige@iee.niit.ac.jp> - - * docs/gnuplot-ja.doc docs/term-ja.diff: Sync Japanese documentation. - -2007-02-10 Ethan Merritt <merritt@u.washington.edu> - - * term/cgm.trm (CGM_options): Remove C++-ism. - - * src/set.c (parse_label_options) : Make sure that there is - a default point type, so that 'set label <n> point' does in fact - draw an acceptable point. - Bug #1652654 - - * term/latex.trm: Re-assign point types to match postscript and - other terminals.

Make use of this to handle transient - use of Symbol font in enhanced text. Does not affect older gd versions. - -2007-01-29 Ethan Merritt <merritt@u.washington.edu> - - * src/axis.c (get_position_default): Because the same parsing routines - are used for both 2D and 3D positions, the trailing comma after a 2D - position can be ambiguous. For example: - plot "foo" with labels offset 1,1, "bar" with points - currently produces an error when the parsing routine tries to interpret - "bar" as a z component of the offset. This patch fixes the common case - shown above, although more pathological cases are still possible. - E.g. plot foo w labels offset 1,1, 4 with lines - -2007-01-28 Ethan Merritt <merritt@u.washington.edu> - - * src/plot2d.c (store_label): Only store color value for each label - in a "with labels" plot if "rgb variable" has been requested. - Bugfix. - -2007-01-27 Ethan Merritt <merritt@u.washington.edu> - - * src/color.h src/graphics.c (plot_image_or_update_axes) - term/pdf.trm (PDF_filled_polygon) src/color.c (filled_quadrangle - filled_polygon_3dcoods filled_polygon_3dcoords_zfixed): - Change gpiPoints to contain signed x,y values.

We can put one - of these in each 2D or 3D plot structure, just as we do for other - specific plot types. This reduces the number of parameters passed - down to rendering routines; now they only need a pointer to the one - structure, in which all other relevant information can be found. - - * docs/gnuplot.doc src/misc.c (get_image_options) src/misc.h: Add an - image property "failsafe".

E.g. - splot $FOO with labels textcolor rgb "blue" point offset -1,1 - - Known limitations: The labels are not handled by hidden3d.

I (personally) think it's better to make the conditionally-compiled -code 'feature-based' rather than 'compiler-based'. I think this is particularly -true for the many DOS compilers. The sort of thing I am thinking of is, -for example, whether to disable hidden3d stuff, or whether to store -data points as float rather than double to save space. Rather than having -a long list of compilers or OS's which use one or the other, add macros -such as SMALLMEMORY or NOHIDDENSTUFF and define these in the makefiles. - Perhaps a sensible guideline for choice of such macros is to arrange -things so that the smallest number of ports are affected. For example, -if we only compiled the hidden stuff if HIDDENSTUFF was defined, most -makefiles would have to be updated. But if instead it is being disabled -for a few machines, only those makefiles have to explicitly define -NOHIDDENSTUFF. - - Perhaps a good guideline would be that gnuplot should build cleanly -with most available features if no macros are defined on an ANSI C compiler -on a 'typical' (POSIX, say) unix machine. - - For example, I myself have broken this rule by requiring the macro -HAVE_LOCALE in order to support setlocale() - this feature is available -with ANSI compilers, and so setlocale() calls should be enabled by default, -and disabled only if NO_LOCALE is defined at compile time. Does this -sound reasonable? For example, there was some code in fit.c that would -prefer to use tempnam() if it is available, but falls back to ANSI fn -tmpnam() if necessary. The way it was done, tempnam() was the default, -and there was a list of those systems that had to use tmpnam(). -But the trouble was that a new one had to be added to the list every -few weeks as new machines were discovered. The current scheme is -that tmpnam() is used unless feature HAVE_TEMPNAM is enabled. - - - -On a related note... if one particular machine does doesn't provide -a standard-ish function, but the same functionality can be -acheived, it would be preferable to implement the standardish -function in a os-specific source file, so that the core code can -simply invoke the function without any conditionals, and the OS-specific -files provide the missing functions. For example, in fit.c (at the -time of writing) where a temporary file is needed, there is some -inline code for DOS, OS2, AMIGA, etc to create temporary files, -otherwise tempnam() is used. I think I'd rather have tempnam() -implemented as a function in dos.c for example, then the fit code -would not need to have any conditional code other than HAVE_TEMPNAM - - - -Also, think generic where possible... I once noticed that popen() -had been implemented for atari or similar using temporary files -and system() call. It seems to me that this could easily be done -as a generic solution, so that DOS ports, for example, could also -benefit. - - - - -FUNCTION PROTOTYPES -------------------- - -Function prototypes are mandatory, even for local functions that are -declared before use. This is necessary for a clean compile on -some machines. gcc -Wstrict-prototypes is recommended. -However, to make the code compilable on pre-ANSI style compilers, -prototypes have to be enclosed in a special macro, e.g. - -int strcmp __PROTO((char *s, char *t)); /* note the double ()'s */ - -Probably from gnuplot release 3.7.1 on, I will require that -all function declarations and definitions are in ANSI style. -I see absolutely no point at all in ignoring the benefits of -ANSI compilers, almost ten years after this language became -an ISO standard. - -int -strcmp(char *s, char *t) -{ - ... -} - -On platforms which use the included configure script, the ansi2knr -tool in the src subdirectory is invoked transparently if the compiler -doesn't support prototypes (Ultrix, SunOS 4.x). Other platforms may -require explicit rules or additional makefiles for non-ANSI/ANSI -compilation. The man page for ansi2knr is included. Note that for -ansi2knr to work, the function return type must be on a separate line, -or, to quote from the ansi2knr manual, "ansi2knr recognizes functions -by seeing a non-keyword identifier at the left margin, followed by a -left parenthesis, with a right parenthesis as the last character on -the line." - - - -While compilers do not require that explicit declarations be -given for integer arguments, we do ! - - -While ANSI compilers can use prototypes for implicit typecasts, k&r -compilers do not have this information. Avoid relying on implicit -conversions of function parameters. gcc -Wconversion helps with this. -There are many signed/unsigned warnings, but look out for other -ones which may be more serious, in particular integer to float and -vice versa. Placing casts is necessary in this case for correct -code on non-ansi compilers. - -[we will definitely give up k&r support in the near future, but - since existing code seems to work with k&r, we're sticking - with it for the time being. -] - -April 2012: Many years later, version 1.12 of the automake toolchain -itself has abandoned support for non-ansification using ansi2knr. -So the above section is of only historical interest. - - - - -INTEGER SIZE ------------- - -Large integer constant expression have to be explicitly cast to long, even -if the result is assigned to a long variable. - -long t=60*60*24; -results in a overflow on 16 bit compilers, even though the result fits into -the long variable. - -Correct: long t=60l*60l*24l; - - - -Similarly, though not particularly important, ANSI and k&r compilers -treat integer constants > MAX_INT differently. If you mean an -unsigned integer constant, say so. - - - - -Please avoid duplicating large sections of code - make the effort -to make a function or macro out of the common code. - - -min(a,b), max(a,b), MIN(a,b), MAX(a,b) are all predefined by some -compilers. I am now using GPMIN() and GPMAX() [wot a pain !] - - -Avoid putting directories into #includes - eg #include "term/file.h" -is to be avoided. Instead, #include "file.h" and use -Iterm on the -compile line. - - -coordval is typedef-ed to either double or float - it is almost always -double, but please take care not to mix coordval's with doubles. - - -An important rule unknown to many, it seems: *never* pass a 'char' to -any of the <ctype.h> functions, as-is. Don't cast it to (int), either ---- that would happen automatically, anyway. You *must* cast to -(unsigned char), instead. Otherwise, there'll quite likely be crashes -with 8-bit characters on systems where 'char' is signed. - - -LAYOUT AND INDENTATION ----------------------- - - The code layout is getting into a bit of a mess, due to mixed -conventions. IMHO the only useful style is one tab stop per -indent. This way, anyone can set their editor to display -with their preferred spacing. More importantly, one has to -delete only one tab to outdent once more : this makes it so much -easier to ensure alignment even if the opening brace is -off the top of the screen. - Much of the code seems to assume tab=8, and uses 4 spaces, -then one tab, then tab+4, then 2tab, ... On an entirely -personal note, this breaks my folding editor :-( - - I think vi does this by default. If using vi, please try -putting set ts=4 into your ~/.exrc file. - - - Unfortunately, gnu indent does not seem to recognise this -as a layout style. If it did, I'd have run all sources -through it long ago. [GNU indent -kr -cp0 -l132 -lps -br -psl -is what I use. Very little manual editing is necessary after -running this, mostly for long (> 80 cols) lines. Anyway, -I don't care which indentation style _you_ use, I'm running -all code through indent and be done with it. -Lars] - - - -Please use lots of vertical whitespace between unrelated -blocks of code in functions. And it should not be need to -be said, but I'll say it anyway... please put in lots of -comments describing blocks of code. Many people maintain and -contribute to this code. - - - The functions in plot?d.c and graph*.c are sometimes very long. -This isn't really a problem, since there's a lot of semi-independent -things to be done in sequence. However, I do object to the -practise of having all variables declared at the top of -such functions. Please keep the scope of temporary variables -as local as possible, particularly in these long functions. -The main reason is for ease of maintenance : many people -make modifications to small parts of code without fully -understanding in exacting detail the surrounding code. - - -In case you were wondering, lines of the form /*{{{ comment */ -and /*}}}*/ are markers left by my folding editor when I am forced -to fold up particularly long functions when trying to understand the -logic. I tend to leave these markers in when I finally figure it out, -though perhaps I should not. - - -Source code is intended to be read and maintained by humans. As such, -readability is prefered over elegance. Please separate all operators -from operands with a space, ie. instead of x+=3, use x += 3.

They are treated as names of -files containing gnuplot commands. Gnuplot loads them, one by one, and -then exits. - -Command 'plot' now has a 'title' option to change the information in -the key. The 'with' option can now specify line type and point type. - -Command 'pause'. - -Command 'replot' allows the addition of extra plots. - -Command 'save' now saves all the 'set' options, including the last -plot command. - -Command 'set autoscale' now accepts autoscaling on the x axis for data -files. The default is autoscaling on both axes. - -Command 'set noclip' disables clipping of points near the border. 'set -clip' reenables clipping. The default used to be 'clip', and is now -'noclip'. Clipping has also been extended to clip lines that extend -outside the borders: line plots are now clipped at the plot boundary. -Formerly, the line stopped at the last in-range data point. - -Numerical labelling at tic marks on x and y axes. Command 'set -format' allows the format of the tic mark labels to be altered. -Commands 'set xtics' and 'set ytics' allow for alphanumeric labels and -arbitrary tic positions. - -Command 'set grid' adds a grid between the tic marks. - -Improved key gives sample point or line types. Key can be disabled -with the 'set nokey'. Key can be positioned anywhere. - -Command 'set label' allows the placement of arbitrary text labels and -arrows. - -Command 'set polar' for polar plots. - -Command 'set offsets' for reducing the plotted area. Useful for polar -plots. - -Command 'set size' scales the displayed size of the plot. - -Command 'set tics out' causes the tics to be drawn outwards from the -border. Useful for impulse plots. - -Command 'set title' places a text label above the plot. - -Commands 'set xlabel' and 'set ylabel' place text labels on the x and -y axes respectively. Some terminals will place the y label vertically -upwards on the left of the plot, others place the label horizontally -at the left of the plot. - -Improved tics on log scales. - -Extended comments: comments are allowed anywhere reasonable in the -input line, and continue to the end of the input line. - -Line continuation (with \) is added. - -Non-interactive use, through redirection or "load" command, is -improved. Error messages expanded to include file name and line -number, and to reprint command line if not interactive. - -New plotting styles 'linespoints' and 'dots'. - -Blank lines in data files denote "breaks". In lines and linespoints -plot styles, this breaks the curve being drawn and begins at the next -point, without changing the line or point types. - -Completely new interactive help system that is similar to VMS help -system. A printed manual can be obtained in LaTeX, troff, or nroff and -is based on the same information as the interactive help. - -PC version now compiles with the large model so that gnuplot will -compile with the above additions! - -Bug fixes include: ------------------- -Bug involving functions plotted on a logarithmic x axis is fixed. - -Errors inside of loaded files now clean up and close files properly. - -Numbers of the form xxxxe+nn are now acceptable (+ sign caused error). - -Tics are now place inside the borders (some were outside). - -Reverse axes now work properly. - -Command 'set output ""' used to crash. - -VMS was closing stdout, so 'set output' code changed to avoid closing -it. VMS version of gnuplot now performs a SET TERM/NOWRAP itself. - -Terminal is now reset before closing output file, changing terminal -type or exiting gnuplot. - -Several old bugs have been superseded by new ones. - - - ACKNOWLEDGEMENTS - -The Unix PC, polar, pause, and offset additions were by John Campbell. -(CAMPBELL@NAUVAX.bitnet) -The Turbo C additions were by Bill Wilson. -(WILSON@NAUVAX.bitnet) -Some of the labelling improvements and combining of these additions -were by Russell Lang. -(rjl@monu1.cc.monash.oz.au) -The LaTeX driver, the help system, and some of the labelling -improvements were by David Kotz. -(David.Kotz@Dartmouth.edu) -And of course, the vast majority of the program is by Colin Kelley -and Thomas Williams. -(info-gnuplot@dartmouth.edu) - -======================================================================= - - GNUPLOT 1.1 RELEASE NOTES - -New terminal drivers: AED 512, BBN BitGraph, HP2623, POSTSCRIPT, -Selanar, Vectrix 384. The PC version now supports Hercules and ATT -6300 monochrome graphics. Thanks to those who sent these drivers in. - -New commands: 'set dummy' and 'show dummy' to select the dummy -variable name; 'replot' to repeat the last 'plot' command. - -The exclamation point (!) is now accepted as postfix factorial -operator. The gamma() function is also included, if your C library -has gamma(). See GAMMA below. - -Logical AND (&&) and OR (||) now short-circuit the way they do in C. -That is, the second && operand is not evaluated if the first is false; -the second || operand is not evaluated if the first is true. The -ternary operator (?:) also does not evaluate the unused operand. This -change allows for the definition of recursive functions, e.g. a -synonym for the ! factorial operator: - - fact(x) = (x<=1) ? 1 : x*fact(x-1) - -GNUPLOT now has a much better memory allocation scheme, replacing most -fixed-size arrays with malloc()'d linked lists. There is no longer -any artificial maximum on the number of simultaneous plots, number of -points in those plots, or the number of user-defined functions or -variables. All these are limited only by the memory available to -malloc(). This is a big improvement for memory-starved machines like -PDP-11s or PCs. - -Lines beginning with # (also ! in VMS) are treated as comments. Only -the $ may now be used for a shell escape in VMS, since ! is a comment. - -Several old bugs have been superseded by new ones. diff --git a/docs/old/Makefile.maint b/docs/old/Makefile.maint deleted file mode 100644 index 89e9a0596..000000000 --- a/docs/old/Makefile.maint +++ /dev/null @@ -1,100 +0,0 @@ -# -*-Makefile-*- -# This Makefile fragment is shared between fileutils, sh-utils, textutils. - -maintainer-check: - if head ChangeLog| grep 'Version $(VERSION)' > /dev/null; then \ - :; \ - else \ - echo "$(VERSION) not in ChangeLog; not tagging" 1>&2; \ - exit 1; \ - fi - $(MAKE) distcheck - $(MAKE) my-distcheck - -# Tag before making distribution.

Of those -not every operation is supported for every curve or surface type and it -can be therefore useful to understand the different types, their advantages -and limitations. - -Curves in gnuplot are almost always planar (with one exception which we -will deal with in the end) and are assumed to be in the XY plane. -Therefore only X and Y coordinates are needed for plotting curves. -The simplest curve is the `explicit function`. This curve is in fact a -function and for each given x, there is one and only one y value associated -with it. A gnuplot example for such type is `plot sin(x)` or -`plot "datafile" using 1". Note the later is using only a single column from -the data file which is assumed to be the y values. - -Alternatively one can define a `parametric curve` form. In this case -x and y are both functions of a third free parameter t, while independent -of each other. A circle can be expressed parametrically as x = cos(t), -y = sin(t) and be plotted using gnuplot as -'set parametric; plot cos(t),sin(t)'. -This form is not a function since there can be unlimited number of y values -associated with same x. Furthermore the explicit form is a special case of -the parametric representation by letting x equal to t. The curve y = sin(x) -can be written in parametric form as y = sin(t), x = t. - -We are used to think of the plane in cartesian coordinate system. -In practice, some coordinate systems may be easier to use then others -under some circumstances. The polar form uses a different basis -to span the XY plane. In this representation the cartesian x coordinate -is equal to r cos(t) and the cartesian y coordinate is equal to r sin(t). -To draw a unit circle using the polar coordinate system in gnuplot use the -following simple command: 'set polar; plot 1'. To better understand this -explicit form lets backup a little. -When we plot a regular explicit function like `y = sin(x)` we march in equal -steps in x, evaluate the provided function and plot a piecewise linear curve -between the sampled points approximating the real function. In the polar -explicit form we do exactly the same thing, but we march along the angular -direction - we turn around the origin, computing the length of the radius -at that angle. Since for the unit circle, this radius is a constant 1, -`plot 1` in polar form plots a circle (if t domain is from 0 or 2Pi). -Note the polar form is explicit in that for each angle there is only a -single radius. - -Surprisingly (or maybe not so surprising) surfaces share the same -representations. Since surfaces are two dimensional entities, they -require two free parameters (like t for curves). - -A surface explicit function uses x and y as the free parameters. For -each such pair it provides a single z value. An example for this form -can be `splot sin(sqrt(x**2+y**2))/sqrt(x**2+y**2)` for a three dimensional -sinc function or `splot 'datafile' using 1`. As for curves, the single column -used from the data file defines the function value or z in this case. -The order of the x and y function values is very strict in this form and -simply defines a rectangular grid in the XY plane. Fortunately this -strict form allows us to apply a very simplistic hidden line algorithm -called "the floating horizon". This hidden line algorithm exploits the -rectangular XY domain of the surface and therefore may be used for this -type of surfaces only. Since in gnuplot this is the only form of hidden -lines removing algorithm provided, only explicit surfaces may have their -hidden lines removed. - -Parametric surfaces are the exact extension for explicit surfaces as in -the curves case. the x, y, and z are defined in terms of two new free -variables and are totally independent of each other as x(u, v), y(u, v), -and z(u, v). Again the explicit surface is a special case of the parametric -representation where x = u, and y = v. Examples for plotting parametric -surfaces in gnuplot can be `splot cos(u)*cos(v),cos(u)*sin(v),sin(u)` which -defines a sphere, or `splot "datafile" using 1:2:3`. Since these are -parametric surfaces, gnuplot must be informed to handle them by issuing -`set parametric`. - -The curve polar form takes the obvious extensions in the surface world. -The first possible extension is spherical coordinate system, while the -second is the cylindrical one. These modes currently work for data files -only and both requires two parameters, theta and phi for mapping onto the -unit sphere, and theta and z form mapping on a unit radius cylinder as follow: - - Spherical coord. Cylin. coord. - ---------------- ------------- - x = cos( theta ) * cos( phi ) x = cos( theta ) - y = sin( theta ) * cos( phi ) y = sin( theta ) - z = sin( phi ) z = z - -This subject brings us back to non planar curves. When surfaces are displayed -under gnuplot, isocurves are actually getting plotted. An isocurve is a -curve on the surface in which one of the two free parameters of the -surface is fixed. For example the u isolines of a surface are drawn by -setting u to be fixed and varying v along the entire v domain. The v isolines -are similarly drawn by fixing v. When data files are specified they are -classified internally into two types. A surface is tagged to have grid -topology if all its specified isolines are of the same length. A data mesh -of five isolines, seven points each is an example. In such a case the -surface cross isolines are drawn as well. Seven isolines with five points -each will be automatically created and drawn for grid type data. If -however, isolines of different length are found in the data, it is -tagged as nongrid surface and in fact is nothing more than a collection -of three dimensional curves. Only the provided data is plotted in that -case (see world.dem for such an example). diff --git a/docs/old/README.3p1 b/docs/old/README.3p1 deleted file mode 100644 index a67506fd8..000000000 --- a/docs/old/README.3p1 +++ /dev/null @@ -1,44 +0,0 @@ -This package provides the upgrade of gnuplot 3.0 to patch level 1. -Below are the contributers to this upgrade and the modifications made. - -Thank you all - -Gershon - ----------------------------------------------------------------------------- - -* Subject: Y log / postscript eps fix - Name: Russell Lang - Email: rjl@monu1.cc.monash.edu.au - -* Subject: HP26 driver to lift text. - Name: Bruce Lueckenhoff - Email: luechen@cis.udel.edu - -* Subject: CRAY prt, UIUC coordinates. - Name: Daniel Lewart - Email: d-lewart@uiuc.edu - -* Subject: AI device - Name: Ray Ghanbari - Email: ray@mtl.mit.edu - -* Subject: HP_MOTIF on a Snake, X11 for Next - Name: Alex Woo - Email: woo@ra-next.arc.nasa.gov - -* Subject: Mod. to LaTeX for multiple curves/plots, complex atan function fix. - Name: Ray Toy??? - Email: toy@soho.crd.ge.com - -* Subject: Fix the "splot 'file.dat'" with only z values. - Name: Gershon Elber - Email: gershon@gr.utah.edu - -* Subject: Underscore prefixed names. - Name: Tom Tkacik - Email: tkacik@hobbes.cs.gmr.com - -* Subject: Amiga port - Name: Carsten Steger - Email: stegerc@informatik.tu-muenchen.de diff --git a/docs/old/README.3p2 b/docs/old/README.3p2 deleted file mode 100644 index 5327a8f8c..000000000 --- a/docs/old/README.3p2 +++ /dev/null @@ -1,105 +0,0 @@ -This is the official release of GNUPLOT.3.2.

Below you can find the -original notes about the implementation, slightly modified in February 2002. - - -The pm3d algorithm: History and description -------------------------------------------- - -The gnuplot pm3d splot mode is a successor to my pm3d algorithm coded -previously in my Turbo Vision Pascal plotting program "pmgraf" for DOS (April -1994) and the C++ command line "pm3d" program which is converting the input -data into postscript maps (March 1995). Both programs are available on my -homepage. - -The pm3d algorithm (in pmgraf, pm3d and now in gnuplot) draws a gray or colour -map (or surface, in gnuplot only) of a 3D data, which are supposed to be a -sequence of scans. Scan is the same what is called 'iso_curve' in gnuplot. - -For the given surface, the algorithm takes one scan after the other scan until -the last but one. For a scan number K it looks at the subsequent scan K+1. For -each (but the last one) point on scan K, it makes a quadrangle with 4 corners: -two subsequent points at scan K and two points at scan K+1. (The quadrangle is -a rectangle if the data are matrix-like.) The quadrangle is filled by the -colour corresponding to the averaged Z coordinate of its 4 corners. - -Therefore it can plot matricial as well as non-rectangular non-gridded data -without any preprocessing, and on single pass through the data. It does not -require that the scans have the same number of points (see the details on -flushing below or 'set pm3d flush'). - - -pm3d implementation in gnuplot ------------------------------- - -Below, you find the basic description of gnuplot implementation of pm3d, colour -palette and filled colour polygons. - -The pm3d implementation in gnuplot is is based on the following terminal -entries (see below for more details): - term->make_palette - term->previous_palette - term->set_color - term->filled_polygon - -The topmost implementation of colour filled areas in plot3d.c: - -(*) pm3d mode is set on if (pm3d.where[0]). Its setting, or using 'with ... -palette', requests the palette of continuous (smooth) colours for the given -terminal according to 'set palette' setup. The palette is created by a call to -make_palette(). The routine make_palette() is coded in pm3d.c. It will be -commented below. - -(*) pm3d plot for a given surface is called from graph3d.c, just before the -stuff for hidden line removal, i.e. before plotting surfaces and contours. For -each surface, it calls - pm3d_plot( this_plot, pm3d.where[i] ); - -(*) The colour box showing the sequence of continuous colours is drawn in routine -draw_color_smooth_box(). Postscript output uses the box implementation directly -in the postscript language, see below. - -(*) Routine term->previous_palette() is called after the plot. Currently, it is -needed only for printing the string "grestore" into a postscript file. - - ------ Implementation of pm3d_plot( this_plot, at_which_z ) in pm3d.c ----- - -(*) This plots the map (for at_which_z=PM3D_AT_BASE or PM3D_AT_TOP) or surface -(for at_which_z=PM3D_AT_SURFACE) for the given surface (variable this_plot). - -(*) The implementation of the pm3d algorithm is schematically: - -for scan J=1 to scans-1 { /* for each scan in the surface */ - for pt=1 to min( points(J), points(J+1) ) { /* go over min nb of points */ - pt' = ...; pt'' = ... /* see below */ - ptJa = point(J,pt') - ptJb = point(J,pt'+1) - ptJ+1a = point(J+1,pt'') - ptJ+1b = point(J+1,pt'') - averagedZ = ( z(ptJa) + z(ptJb) + z(ptJ+1a) + z(ptJ+1b) ) / 4 - set_color( averagedZ normalized to [0;1] ) - fill_polygon( 4 corners, - those 4 points transformed into coordinates of - the map or surface on the terminal ) - } - } - -If the two subsequent scans have the same number of points, then pt''=pt'=pt. -Otherwise, pt''=pt'=pt if 'scans flushed begin', pt'=points(J)-pt and -pt''=points(J+1)-pt if 'scans flushed end', and similarly for 'scans center'. -And nothing is drawn if there is only one point in the scan. - - ------ Implementation of make_palette() in pm3d.c ----- - -(*) Look into color.h, structure t_sm_palette: declaration of smooth palette, -i.e. palette for smooth colours. It documents how gray [0,1] is mapped into -(R,G,B) = ([0,1], [0,1], [0,1]). - -(*) Ask for the number of colours that are (still) available on the current -terminal: - i = term->make_palette(NULL); - -Postscript terminal returns 0 since it supports all RGB values (no limit on -discrete number of colours). It has its own mapping: transformation of gray -[0,1] is coded as postscript functions, and also in order to make the output -size of the postscript file as small as possible, i.e. the same as the output -from the pm3d program. Further, not 3 values of the RGB triplet but only 1 gray -value is written into the postscript file. This is achieved by the analytical -functions: pm3dGetColorValue() are coded as postscript functions, see post.trm: -PostScriptColorFormulae[] used in PS_make_palette entry. PS->make_palette() -looks itself into sm_palette and writes a header with the appropriate -postscript codes for formulaR, formulaG, formulaB transformations. See also -post.trm: PostScriptColorFormulae[] used in PS_make_palette. Return from -make_palette(). - -All other terminals have discrete number of colours. Currently an RGB palette -is allocated for the number of available colours returned by make_palette(); if -pm3d is used in gnuplot's multiplot mode, then the result would be incorrect if -the previous palette is not reused or if the number of colours is not limited -by 'set palette maxcolors'. - -Creating the RGB palette: make the array of (RGB) triplets according to items in -sm_palette (not for postscript) - sm_palette.color = malloc( sm_palette.colors * sizeof(rgb_color) ); - -And then -for (i = 0; i < sm_palette.colors; i++) { - gray = (double)i / (sm_palette.colors - 1); /* rescale to [0;1] */ - if (sm_palette.ColorMode == colorModeGRAY) /* gray scale only */ - sm_palette.color[i].r = sm_palette.color[i].g = sm_palette.color[i].b - = gray; - else { /* i.e. sm_palette.ColorMode == colorModeRGB */ - sm_palette.color[i].r = pm3dGetColorValue(sm_palette.formulaR, gray); - sm_palette.color[i].g = pm3dGetColorValue(sm_palette.formulaG, gray); - sm_palette.color[i].b = pm3dGetColorValue(sm_palette.formulaB, gray); - } - } - -Finally, tell the terminal to allocate the palette for the (RGB) triplets -(again, not for postscript) - term->make_palette(&sm_palette); - - ------ Transformation of the z-coordinate to gray and RGB in pm3c.c ----- - -How a colour is transformed from the gray? AveragedZ is mapped into the -interval [min_z:max_z] which is transformed into [0:1], see routine - double z2gray ( double z ) -which rescales z into the interval [0,1]. This works fine also for the -logarithmic z axis. Later, this is used by - gray = z2gray ( avgZ ); -This value can be used directly as a gray for gray maps. For colour maps -it further needs to transform - gray -> (R,G,B): [0:1] -> ([0:1], [0:1], [0:1]) -thus some nice three functions have to be choosen --- see pm3d.c, function -pm3dGetColorValue(), for the available mapping functions. - -Note that after the complete separation of the z and cb axes (cb-axis is the -axis of colors) in February 2002, there is a new function z2cb(), and z2gray() -was replaced by cb2gray(). - - ------ Implementation of pm3d terminal entries in *.trm ----- - -In this section you will find a brief discussion on the following pm3d-related -terminal entries: - term->make_palette - term->previous_palette - term->set_color - term->filled_polygon -which are required to make pm3d to work. Files considered by these functions -are color.h, color.c, plot.h, and all .trm which are pm3d-capable. If you are -coding pm3d support for a new terminal, then you can have a look at the code -in these files: - gif.trm (bitmap GIF terminal implementation), - post.trm (PostScript terminal implementation), - pm.trm + gclient.c (OS/2 PM terminal implementation), - x11.trm + gplt_x11.c (X11 terminal implementation). - -The pm3d-specific code is surrounded by #ifdef PM3D ... #endif, so it is -possible to compile gnuplot with or without pm3d support just bey (un)defining -the PM3D constant. - -In plot.h, the following new terminal entries are added into struct TERMENTRY: - -int (*make_palette)(t_sm_palette *palette); - 1. If palette==NULL, then return nice/suitable maximal number of colours - supported by this terminal. Returns 0 if it can make colours without - palette (like postscript). - 2. If palette!=NULL, then allocate its own palette return value is - undefined. - 3. Available: some negative values of max_colors for whatever it can be - useful. - - Some particular notes: - (*) Terminals with palette (GIF, PM): there are already some basic colours - allocated (see gnuplot command 'test'), thus an offset for the `part with - smooth colours' is needed. - (*) GIF: can allocate up to 256 colours, i.e. discrete number of colours. - (*) PM: discrete number of colours. Passes the rgbTable through the pipe - into standalone gnupmdrv driver. X11 should be implemented in the same - way. - (*) PostScript: continuous colours, as "setrgbcolor" PS command takes the - triplet of intervals [0,1]. - -void (*previous_palette)(void); - Release the palette that the above routine allocated and get back the - palette that was active before. Some terminals, like displays, may draw - parts of the figure using their own palette. The terminals possessing only - one palette for the whole plot don't need this routine. - - Actually, this routine is currently used only for postscript terminal, - where it writes "grestore" as make_palette() starts its postscript - definitions by "gsave"... that's because there are the analytical mapping - functions gray->RGB defined in the local header. - -void (*set_color)(double gray); - The value of gray is [0;1]. The terminal uses its color palette or any - other way to transform in into true gray or to r,g,b. This terminal entry - remembers (or not) this colour so that it can reuse it for a subsequent - drawing (for each terminal separately). - -void (*filled_polygon)(int points, gpiPoint *corners); - The declaration has been made the same as in GIF's gd.h. It fills the given - polygon according to color set by the previous call to set_color(). - - -******************************************************************************* -******************************************************************************* - -TECHNICAL DETAILS ABOUT PLOT WITH IMAGE -======================================= - -The plot_image() routine in graphics.c was added by Daniel Sebald on October -30, 2003. It is intended for plotting images if the terminal driver supports -images, otherwise it reverts to pm3d color boxes if possible. A large part of -the routine checks that the visible points form a valid rectangular grid. -Because the data is in the form of 2D/3D point structures, this must be done. -(A future feature might be the ability to circumvent the large storage -requirements of 2D/3D point structures and the need to check whether data -forms a grid whenever the user supplies image data in a known matrix format.) - -If a grid aligned with the Cartesian axes is not given, plot_image() will -revert to plotting each pixel as a color boxes using term->filled_polygon(). -This same fallback to individual polygons is used to render images on -terminals that have no term->image() entry point. This mode can also be -forced by the keyword "failsafe": ... with {rgb}image {failsafe}. - -Only details about the "tricky" algorithms are given here. - -There are eight valid ways that pixel grid information can be entered via the -plot->points[] array. These are based upon the scanning direction (i.e., along -one of the dimensions) and the two directions (positive vs. negative) along -the dimensions that the points are entered. - -Definitions: - - K = input scan line length (i.e., number of samples along line) - L = input plane length (i.e., number of scan lines) - dim = dimension (0 means increments along x, 1 means increments along y) - dxg0 = delta x grid along the scan line (can be positive or negative) - dyg0 = delta y grid along the scan line (can be positive or negative) - dxg1 = delta x grid between scan lines (can be positive or negative) - dyg1 = delta y grid between scan lines (can be positive or negative) -sgn() = sign of variable (- represented as 0, + represented as 1) - a^b = raise a to the power b - M = output row length (i.e., number of columns) - N = output column length (i.e., number of rows) - -The goal is to move the data from the plot->points[] array to the matrix pixel -grid in the order (1,1), (1,2), (1,3), ..., (M,N-1), (M,N) forming the M x N -matrix - - (1,1)...(M,1) - . . - . . - . . - (1,N)...(M,N) - -(Note that the terminal scale, positive or negative, has an influence on the -orientation of pixels. Ignore this temporarily for simplicity. Formulas are -augmented later to account for axes directions.) The approach is to step -through the plot points and copy each visible point to its appropriate spot in -the image matrix array. The routine that does this is fundamentally - - for (i=0, j=line_length, i_image=i_start; i < plot->p_count; i++) { - image[i_image] = plot->points[i].CRD_COLOR; - i_image += i_delta_pixel; - j--; - if (j == 0) { - i_image += i_delta_line; - j = line_length; - } - } - -Thus the indexing parameters i_start, line_length, i_delta_pixel and -i_delta_line must be determined. line_length is solely dependent upon the -dimension; K if dimension = 0 (i.e., increment along a row) and L if -dimension = 1 (i.e., along column). The other relationships can be determined -by looking at the eight 4 x 2 illustrations which follow. Assume points are -entered 0, 1, 2, 3, 4, 5, 6, 7, then the various ways of entry are: - - (1) (2) (3) (4) (5) (6) (7) (8) - -3 2 1 0 7 6 5 4 0 1 2 3 4 5 6 7 6 4 2 0 7 5 3 1 0 2 4 6 1 3 5 7 -7 6 5 4 3 2 1 0 4 5 6 7 0 1 2 3 7 5 3 1 6 4 2 0 1 3 5 7 0 2 4 6 - -The functions are: - -sgn(dyg1)---------| -sgn(dxg1)------ | -sgn(dyg0)-- | | i_delta_pixel -sgn(dxg0) | | | | - | | | | i_start | | | i_delta_line - --- --- --- --- | -------------------- | ------- | --------------- -(1) - 0 0 - | K - 1 = K*1 - 1 | -1 | 2*K = K + K -(2) - 0 0 + | K*L - 1 = K*L - 1 | -1 | 0 = K - K -(3) + 0 0 - | 0 = K*1 - K | 1 | 0 = -K + K -(4) + 0 0 + | K*(L-1) = K*L - K | 1 | -2*K = -K - K - | | | -(5) 0 - - 0 | (L-1)*K = K*L - K | -K | K*L + 1 -(6) 0 + - 0 | K*L - 1 = K*L - 1 | -K | K*L - 1 -(7) 0 - + 0 | 0 = K*1 - K | K | -K*L + 1 -(8) 0 + + 0 | K - 1 = K*1 - 1 | K | -K*L - 1 - - - -There is a clear distinction between formulas based upon dimension. -Summarizing, - - - dimension = 0 (x changing) -------------------------------------------------------- -line_length: K - -i_start: L^(dyg1 > 0) * K - K^(dxg0 > 0) - -i_delta_pixel: (-1)^(dxg0 < 0) - -i_delta_line: K*[(-1)^(dxg0 > 0) + (-1)^(dyg1 > 0)] -------------------------------------------------------- - - - - dimension = 1 (y changing) -------------------------------------------------------- -line_length: L - -i_start: L^(dxg1 < 0) * K - K^(dyg0 < 0) - -i_delta_pixel: K*(-1)^(dxg1 < 0) - -i_delta_line: K*L*(-1)^(dxg1 > 0) + (-1)^(dyg0 > 0) -------------------------------------------------------- - - -The above formulas are what appear preceding the for() loop in the actual code -except for one detail, the terminal scale, i.e., direction for which the axes -are increasing.

The function - - void (*image) __PROTO((unsigned M, unsigned N, coordval *image, - gpiPoint *corner, int color_mode)); - -is the terminal driver routine for displaying an image. 'M' is the number of -rows, 'N' is the number of columns, 'image' is a pointer to image data stored -with upper left pixel first and scanning horizontally from left to right, -'corner' contains - - corner[0].x upper left pixel (1,1) location (extent) of image - corner[0].y - corner[1].x lower right pixel (M,N) location (extent) of image - corner[1].y - corner[2].x upper left corner of visible window - corner[2].y - corner[3].x lower right corner of visible window - corner[3].y - -and 'color_mode' indicates if the image should use RGB triples or palette -lookup. - -Image samples are a coordval which is a float. Image data attempts to be -consistent with the color schemes of Petr Mikulik's pm3d. Therefore, the -values in the image array are in the range [0.0,1.0] and the terminal driver -routine can handle this data by mapping this range to a range appropriate for -the output device. - -If `color_mode` is IC_RGB, the `image` array should be treated as triples of -floats. That is, rather than the length of the image array being M*N, as is -the case when `color_mode` is IC_PALETTE, the length of the array is 3*M*N. -Triples are of the form - -image[0] = red 1,1 -image[1] = green 1,1 -image[2] = blue 1,1 -image[3] = red 1,2 -image[4] = green 1,2 -image[5] = blue 1,2 -etc. - -When in IC_PALETTE mode, image data should be used as an index into the -palette constructed by the make_palette() terminal routine. That is, one -should multiply the value by the palette size minus one, cast to an integer -and range check (good practice) the index. - -The meaning of the corners is that the first two represent the outer extent of -the pixels representing the image; not the centers of the pixels on the outer -edge, but the outer edge of the pixels on the outer edge. The next two corners -represent the extent of the visual, or clipping region. Thus, on the outer -edge of the image may be pixels which are only fractionally displayed. - - -TECHNICAL DETAILS ABOUT X11 IMAGE DRIVER -======================================== - -Support for images in the X11 driver was added by Daniel Sebald on February -27, 2003. - -For X11, this image terminal function is X11_image(). Because of the large -amount of data associated with an image, the routine avoids using floats and -avoids using formatted I/O representation for numbers. The "scanf" function -is a very inefficient routine for large amounts of data. - -To avoid using floats, the maximum resolution of the color plane of the X11 -device is assumed to be 16 bits. (Not an unreasonable assumption.) The image -data is converted to short by multiplying by the maximum palette value. On -the gplt_x11.c side of the pipe, these unsigned short values are shifted to -the right to match the size of its palette. - -To avoid using formatted I/O. A simple encoding scheme is used to eliminate -all image data values having a value equivalent to a '\n' character or a '\0' -character because the core gplt_x11.c routine interprets these characters in -a special way. The scheme is as follows: if the character '\n' or '\0' are -found, they are replaced by a two byte representation (CODE_WORD,value+1). -On the receiving side, if the CODE_WORD is found, the next byte after it minus -one is the decoded character. Naturally, the CODE_WORD itself must also be -encoded so as to not lose those in the data stream. - -An additional step is to first translate the data before sending it over the -pipe. This is done by subtracting a constant. The constant is added back -in on the other side. The reason for this is that image data often contains -many 0 characters (e.g., upper 8 bits). Thus the character '\0' is prevalent -in image data, and without translation, the encoding scheme would result in -noticable expansion of the data stream. The encoding is meant to cut down the -amount of data that is stored in the gplt_x11.c replot buffers. - -Because there may be an endianess problem if the gnuplot and gnuplot_x11 -programs were compiled under different compilers, Petr and Dan added an endian -check command. If this check finds it is necessary to swap bytes in encoded -binary data coming across the pipe, then gnuplot_x11 will do so for those -commands using encoded binary. In most cases, these programs will have been -compiled with the same compiler so byte swapping will not be done. But it is -there just in case. - -The X11 color bit packing is a bit tricky. It attempts to be portable, but I'm -sure there are peculiar hardware formats out there that will not work properly -as it currently exists. (Some additions and tweaking will probably be need, -but without examples of every hardware configuration it is difficult to program -for them.) Basically, shifts and masking for packing the bits from the RGB -data (16 bits per channel) are derived from the masks of the X11 display -information. Also, there is hardware option of byte order: most significant -byte first or least significant byte first. The routine will swap bytes if -necessary. However, if the bytes need to be swapped and the RGB masks are all -8 bits, then the swapping can be done inherently by appropriately altering the -bit shifts. For example, say the masks are R: 0xff0000, G: 0xff00, B: 0xff -and bytes need to be swapped. Rather than using these masks and swapping -bytes, the masks could be changed to R: 0xff00, G: 0xff0000, B: 0xff000000. - -Comments: - -The method works rather well, short of a more direct method of storing image -data in gplt_x11.c without having to pull the data out of the replot buffer for -every refresh. The new 2D binary data file entry (well documented in the -gnuplot.doc file) in concert with the image routines was suppose to make Octave -fast at drawing images. However, Octave needs some reworking yet to make this -happen seamlessly. The problem is that Octave does not yet use binary data but -instead uses ASCII data files to get information to Gnuplot. I've attempted to -write data to a file in binary format using Octave's fwrite() routine then use -Octave's graw() routine. This speeds things up somewhat, but I still think -this interface can be improved at a later time. - - -TECHNICAL DETAILS ABOUT POSTSCRIPT IMAGE DRIVER -=============================================== - -The PostScript image driver is rather straightforward. Its main processing -involves encoding the data in ASCII85 format. No compression scheme is used -currently. Run length encoding hardly seems worth the effort because in most -cases the amount of compression won't be too significant, I'm guessing. For -image data, other than the single bit variety such as a facsimile, other forms -of compression are more efficient. - -******************************************************************************* -******************************************************************************* - -COMMENTS ABOUT BINARY DATA FILE SYNTAX -====================================== - -A keyword for binary data indicates which way to scan within the file.

Data files should contain one data point per line. -Lines beginning with \# (or ! on VMS) will be treated as comments -and ignored. For {\bf plot}s, each data point represents an (x,y) -pair. For {\bf splot}s, each point is an (x,y,z) triple. For {\bf plot}s with -error bars (see {\bf plot errorbars}), each data point is either -(x,y,ydelta), (x,y,ylow,yhigh), (x,y,xlow,xhigh), (x,y,xdelta,ydelta), or -(x,y,xlow,xhigh,ylow,yhigh). In all cases, the numbers on each -line of a data file must be separated by blank space. This blank -space divides each line into columns. - -For {\bf plot}s the x value may be omitted, and for {\bf splot}s the x -and y values may be omitted. In either case the omitted values are -assigned the current coordinate number. Coordinate numbers start at 0 -and are incremented for each data point read. - -\section{Surface Plotting} -Implicitly, there are two types of 3-d datafiles. If all the isolines -are of the same length, the data is assumed to be a grid data, i.e., -the data has a grid topology. Cross isolines in the other parametric -direction (the ith cross isoline passes thru the ith point of all the -provided isolines) will also be drawn for grid data. (Note contouring -is available for grid data only.) If all the isolines are not of the -same length, no cross isolines will be drawn and contouring that data -is impossible. - -\section{Using Pipes} - -On some computer systems with a popen function (Unix, plus some -others), the datafile can be piped through a shell command by starting -the file name with a '$<$'. For example: - - pop(x) = 103*exp(x/10) - plot "$<$ awk '$\{$ print \$1-1965 \$2 $\}$' population.dat", pop(x) - -would plot the same information as the first population example -but with years since 1965 as the x axis. Simple manipulations -of this kind can also be done using the extended capabilties of {\bf using} - -Similarly, output can be piped to another application, e.g. - - set out "$|$lpr -Pmy\_laser\_printer" - -\section{Plot Data Using} -The format of data within a file can be selected with the {\bf using} -option. An explicit scanf string can be used, or simpler column -choices can be made. - -\key{plot "datafile"}{ $\{$ using $\{ <$ycol$> |$} -\key{}{$<$xcol$>:<$ycol$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$ydelta$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$width$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$xdelta$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$ylo$>:<$yhi$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$xlo$>:<$xhi$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$xdelta$>:<$ydelta$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$ydelta$>:<$width$> |$} -\key{}{$<$xcol$>:<$ycol$>:<$ylo$>:<$yhi$>:<$width$> |$} -\key{}{$<$xc$>:<$yc$>:<$xlo$>:<$xhi$>:<$ylo$>:<$yhi$> \}$} -\key{}{$\{$"<scanf string>"$\} \} ...$} - -\key{splot "datafile"} -{$\{$ using $\{ <$xcol$>:<$ycol$>:<$zcol$> \}$} -\key{}{$\{"<$scanf string$>"\} \} ...$} - -$<$xcol$>$, $<$ycol$>$, and $<$zcol$>$ explicitly select the columns -to plot from a space or tab separated multicolumn data file. If only -$<$ycol$>$ is selected for {\bf plot}, $<$xcol$>$ defaults to 1. If -only $<$zcol$>$ is selected for {\bf splot}, then only that column is -read from the file. An $<$xcol$>$ of 0 forces $<$ycol$>$ to be plotted -versus its coordinate number. $<$xcol$>$, $<$ycol$>$, and $<$zcol$>$ -can be entered as constants or expressions. Expressions enclosed in -parentheses can be used to compute a column data value from all -numbers in the input record. - -If errorbars (see also {\bf plot errorbars}) are used for {\bf plot}s, -xdelta or ydelta (for example, a +/- error) should be provided as the -third column, or (x,y)low and (x,y)high as third and fourth columns. -These columns must follow the x and y columns. If errorbars in both -directions are wanted then xdelta and ydelta should be in the third -and fourth columns, respectively, or xlow, xhigh, ylow, yhigh should -be in the third, fourth, fifth, and sixth columns, respectively. - -Scanf strings override any $<$xcol$>$:$<$ycol$>$(:$<$zcol$>$) choices, -except for ordering of input, e.g., - -\key{plot "datafile"}{ using 2:1 "\%f\%*f\%f"} - -causes the first column to be y and the third column to be x. - -If the scanf string is omitted, the default is generated based on the -$<$xcol$>$:$<$ycol$>$(:$<$zcol$>$) choices. If the {\bf using} option -is omitted, ''\%f\%f'' is used for {\bf plot} (''\%f\%f\%f\%f'' or -''\%f\%f\%f\%f\%f\%f'' for {\bf errorbar} {\bf plot}s) and -''\%f\%f\%f'' is used for {\bf splot}. - -\key{plot "MyData"} {using "\%*f\%f\%*20[^$\backslash$n]\%f" w lines} - -Data are read from the file ``MyData'' using the format -''\%*f\%f\%*20[^$\backslash$n]\%f''. The meaning of this format is: -''\%*f'' ignore the first number, ''\%f'' then read in the second and -assign to x, ''\%*20[^$\backslash$n]'' then ignore 20 non-newline -characters, ''\%f'' then read in the y value. - -\section{Plot With Errorbars} -Error bars are supported for 2-d data file plots by reading one to -four additional columns specifying ydelta, ylow and yhigh, xdelta, -xlow and xhigh, xdelta and ydelta, or xlow, xhigh, ylow, and yhigh -respectively. No support exists for error bars for {\bf splot}s. - -In the default situation, gnuplot expects to see three to six -numbers on each line of the data file, either (x, y, ydelta), -(x, y, ylow, yhigh), (x, y, xdelta), (x, y, xlow, xhigh), -(x, y, xdelta, ydelta), or (x, y, xlow, xhigh, ylow, yhigh). The x -coordinate must be specified. The order of the numbers must be exactly -as given above. Data files in this format can easily be plotted with error -bars: - - plot "data.dat" with errorbars (or yerrorbars) - - plot "data.dat" with xerrorbars - - plot "data.dat" with xyerrorbars - -The error bar is a line plotted from (x, ylow) to (x, -yhigh) or (xlow, y) to (xhigh, y). If ydelta is specified instead -of ylow and yhigh, ylow=y-ydelta and yhigh=y+ydelta are derived. The -values for xlow and xhigh are derived similarly from xdelta. If there -are only two numbers on the line, yhigh and ylow are both set to -y and xhigh and xlow are both set to x. To get lines plotted between -the data points, {\bf plot} the data file twice, once with errorbars and -once with lines. - -If x or y autoscaling is on, the x or y range will be adjusted to fit the -error bars. - -Boxes may be drawn with y error bars using the {\bf boxerrorbars} style. The -width of the box may be either set with the "set boxwidth" command, given in -one of the data columns, or calculated automatically so each box touches the -adjacent boxes. -Boxes may be drawn instead of the cross drawn for the {\bf xyerrorbars} style -by using the {\bf boxxyerrorbars} style. - -\key{x,y,ylow \& yhigh from columns 1,2,3,4}{plot "data.dat" us 1:2:3:4 w errorbars} -\key{x from third, y from second, xdelta from 6}{plot "data.dat" using 3:2:6 w xerrorbars} -\key{x,y,xdelta \& ydelta from columns 1,2,3,4}{plot "data.dat" us 1:2:3:4 w -xyerrorbars} - -\section{Plot Ranges} -The optional range specifies the region of the plot that will be -displayed. - -Ranges may be provided on the {\bf plot} and {\bf splot} command line and -affect only that plot, or in the {\bf set xrange}, {\bf set yrange}, etc., -commands, to change the default ranges for future plots. - -\key{[$\{<$dummy-var$> =\} \{<$xmin$> : <$xmax$>\}$]} { $\{$ [$\{<$ymin$> : <$ymax$>\}$] $\}$} - -where $<$dummy-var$>$ is the independent variable (the defaults are x and -y, but this may be changed with {\bf set dummy}) and the min and max -terms can be constant expressions. - -Both the min and max terms are optional. The ':' is also optional -if neither a min nor a max term is specified. This allows '[ ]' to -be used as a null range specification. - -Specifying a range in the {\bf plot} command line turns autoscaling for -that axis off for that plot. Using one of the {\bf set} range commands -turns autoscaling off for that axis for future plots, unless changed -later. (See {\bf set autoscale}). - -\key{This uses the current ranges}{plot cos(x)} -\key{This sets the x range only}{plot [-10:30] sin(pi*x)/(pi*x)} -\key{This sets both the x and y ranges}{plot [-pi:pi] [-3:3] tan(x), 1/x} -\key{sets only y range, \&} {plot [ ] [-2:sin(5)*-8] sin(x)**besj0(x)} -\key{turns off autoscaling on both axes}{} -\key{This sets xmax and ymin only}{plot [:200] [-pi:] exp(sin(x))} -\key{This sets the x, y, and z ranges}{splot [0:3] [1:4] [-1:1] x*y} - -\section{Plot With Style} -Plots may be displayed in one of twelve styles: {\bf lines}, {\bf points}, -{\bf linespoints}, {\bf impulses}, {\bf dots}, {\bf steps}, -{\bf errorbars} (or {\bf yerrorbars}), {\bf xerrorbars}, {\bf xyerrorbars}, -{\bf boxes}, {\bf boxerrorbars}, or {\bf boxxyerrorbars}. The {\bf lines} style -connects adjacent points with lines. The {\bf points} style displays a -small symbol at each point. The {\bf linespoints} style does both -{\bf lines} and {\bf points}. The {\bf impulses} style displays a vertical line -from the x axis (or from the grid base for {\bf splot}) to each point. The -{\bf dots} style plots a tiny dot at each point; this is useful for -scatter plots with many points. The {\bf steps} style is used for drawing -stairstep-like functions. The {\bf boxes} style may be used for barcharts. - -The {\bf errorbars} style is only relevant to 2-d data file plotting. It -is treated like {\bf points} for {\bf splot}s and function {\bf plot}s. For -data -{\bf plot}s, {\bf errorbars} is like {\bf points}, except that a vertical error -bar is also drawn: for each point (x,y), a line is drawn from -(x,ylow) to (x,yhigh). A tic mark is placed at the ends of the error -bar. The ylow and yhigh values are read from the data file's columns, -as specified with the {\bf using} option to plot. The {\bf xerrorbars} -style is similar except that it draws a horizontal error bar from xlow to -xhigh. The {\bf xyerrorbars} or {\bf boxxyerrorbars} style is used for data -with errors in both x and y. A barchart style may be used in conjunction with y -error bars through the use of {\bf boxerrorbars}. The See {\bf plot errorbars} -for more information. - -Default styles are chosen with the {\bf set function style} and -{\bf set data style} commands. - -By default, each function and data file will use a different -line type and point type, up to the maximum number of available -types. All terminal drivers support at least six different point -types, and re-use them, in order, if more than six are required. -The LaTeX driver supplies an additional six point types (all variants -of a circle), and thus will only repeat after twelve curves are -plotted with points. - -If desired, the style and (optionally) the line type and point type -used for a curve can be specified. - -\key{with $<$style$>$}{$ \{<$linetype$> \{<$pointtype$>\}\}$} - -where $<$style$>$ is either {\bf lines}, {\bf points}, {\bf linespoints}, {\bf impulses}, -{\bf dots}, {\bf steps}, {\bf errorbars} (or {\bf yerrorbars}), -{\bf xerrorbars}, {\bf xyerrorbars}, {\bf boxes}, {\bf boxerrorbars}, -{\bf boxxyerrorbars}. - -The $<$linetype$>$ \& $<$pointtype$>$ are positive -integer constants or expressions and specify the line type and point -type to be used for the plot.

If {\bf linear}, then the contours are drawn piecewise -linear, as extracted from the surface directly. If {\bf cubicspline}, then -piecewise linear contours are interpolated to form a somewhat smoother -contours, but which may undulate. The third option is the uniform -{\bf bspline}, which only approximates the piecewise linear data but is -guaranteed to be smoother. - -{\bf points} - Eventually all drawings are done with piecewise linear -strokes. This number controls the number of points used to -approximate a curve. Relevant for {\bf cubicspline} and {\bf bspline} modes -only. - -{\bf order} - Order of the bspline approximation to be used. The bigger this -order is, the smoother the resulting contour. (Of course, higher order -bspline curves will move further away from the original piecewise linear -data.) This option is relevant for {\bf bspline} mode only. Allowed values are -integers in the range from 2 (linear) to 10. - -{\bf levels} - Number of contour levels, 'n'. Selection of the levels is -controlled by 'auto' (default), 'discrete', and 'incremental'. For 'auto', -if the surface is bounded by zmin and zmax then contours will be -generated from zmin+dz to zmax-dz in steps of size dz, where -dz = (zmax - zmin) / (levels + 1). For 'discrete', contours will be -generated at z = z1, z2 ... as specified. The number of discrete levels -is limited to MAX\_DISCRETE\_LEVELS, defined in plot.h to be 30. If -'incremental', contours are generated at $<$n$>$ values of z beginning at -$<$start$>$ and increasing by $<$increment$>$. - -\section{Specifying Labels} -Arbitrary labels can be placed on the plot using the {\bf set label} -command.

If no $<$tag$>$ is given, the -lowest unused tag value is assigned automatically. The tag can be used -to delete or change a specific label. To change any attribute of an -existing label, use the {\bf set label} command with the appropriate tag, -and specify the parts of the label to be changed. - -By default, the text is placed flush left against the point x,y,z. -To adjust the way the label is positioned with respect to the point -x,y,z, add the parameter $<$justification$>$, which may be {\bf left}, {\bf right} -or {\bf center}, indicating that the point is to be at the left, right or -center of the text. Labels outside the plotted boundaries are -permitted but may interfere with axes labels or other text. - -\key{label at (1,2) to ``y=x'' }{set label "y=x" at 1,2} -\key{label ``y=x^2'' w right of the text at (2,3,4), } -{set label 3 "y=x^2" at 2,3,4 right} -\key{\& tag the label number 3 }{} -\key{change preceding label to center justification}{set label 3 center} -\key{delete label number 2 }{unset label 2} -\key{delete all labels}{unset label} -\key{show all labels (in tag order)}{show label} - -(The EEPIC, Imagen, LaTeX, and TPIC drivers allow $\backslash$$\backslash$ -in a string to specify a newline.) - -\section{Miscellaneous Commands} - -For further information on these commands, print out a copy -of the gnuplot manual. - -\key{change working directory}{cd} -\key{erase current screen or device}{clear} -\key{exit gnuplot}{exit or quit or EOF} -\key{display text and wait}{pause <time> ["<string>"]} -\key{print the value of $<$expression$>$}{print <expression>} -\key{print working directory}{pwd} -\key{repeat last {\bf plot} or {\bf splot}}{replot} -\key{spawn an interactive shell}{! (UNIX) or \$ (VMS)} - -\section{Environment Variables} - -A number of shell environment variables are understood by gnuplot. -None of these are required, but may be useful. -See 'help environment' for the complete description. - -If GNUTERM is defined, it is used as the name of the terminal type to -be used. This overrides any terminal type sensed by gnuplot on start -up, but is itself overridden by the .gnuplot (or equivalent) start-up -file (see {\bf start-up}), and of course by later explicit changes. - -On Unix, OS/2, and MS-DOS, GNUHELP may be defined to be the pathname -of the HELP file (gnuplot.gih). - -On VMS, the symbol GNUPLOT\$HELP should be defined as the name of -the help library for gnuplot. - -On Unix, HOME is used as the name of a directory to search for -a .gnuplot file if none is found in the current directory. -On OS/2 and MS-DOS, GNUPLOT is used to search for gnuplot.ini file. -On VMS, SYS\$LOGIN: is used. See 'help start-up'. - -GNUPLOT\_LIB may be used to define additional search directories for -data and command (script) files. - -On Unix, PAGER is used as an output filter for help messages. - -GDFONTPATH is the directory where png terminal searches TrueType fonts, -i.e.~files like arial.ttf. -GNUPLOT\_FONTPATH is that for the postscript terminal. - -On Unix, SHELL is used for the {\bf shell} command. On MS-DOS, -COMSPEC is used for the {\bf shell} command. - -On MS-DOS, if the BGI interface is used, the variable {\bf BGI} is used to point -to the full path to the BGI drivers directory. Furthermore SVGA is used to -name the Super VGA BGI driver in 800x600 res., and its mode of operation -as 'Name.Mode'. -For example, if the Super VGA driver is -C:$\backslash$TC$\backslash$BGI$\backslash$SVGADRV.BGI -and mode 3 is used for 800x600 res., then: -'set BGI=C:$\backslash$TC$\backslash$BGI' and 'set SVGA=SVGADRV.3'. - -GNUFITLOG holds the name of a directory or a file that saves fit results. - - -\section{Expressions} -In general, any mathematical expression accepted by C, FORTRAN, -Pascal, or BASIC is valid. The precedence of these operators is -determined by the specifications of the C programming language. -White space (spaces and tabs) is ignored inside expressions. - -Complex constants may be expressed as $\{<$real$>,<$imag$>\}$, where -$<$real$>$ and $<$imag$>$ must be numerical constants. For example, -$\{3,2\}$ represents 3 + 2{\bf i} and $\{0,1\}$ represents {\bf i} -itself. The curly braces are explicitly required here. -\section{Functions} -The functions in gnuplot are the same as the corresponding functions -in the Unix math library, except that all functions accept integer, -real, and complex arguments, unless otherwise noted. The {\bf sgn} -function is also supported, as in BASIC. - -%\begin{center} -%\begin{tabular}{|ccl|} \hline -{ -\catcode`\^=7 -\catcode`\_=8 -\def\ff#1{\hbox{\rm #1}\,} -\def\fff#1{\hbox{\rm #1}\,} -\def\sin{\ff{sin}} -\def\cos{\ff{cos}} -\def\tan{\ff{tan}} -\def\sinh{\ff{sinh}} -\def\cosh{\ff{cosh}} -\def\tanh{\ff{tanh}} -\def\log{\fff{log}} - -\settabs 5\columns -\+Function & Arguments & Returns \cr -\hrule%\hline -\+ abs(x) & any & absolute value of {\tt x}, $|x|$; same type \cr -\+ abs(x) & complex & length of {\tt x}, $\sqrt{{\hbox{real}(x)^{2} + -\hbox{imag}(x)^{2}}}$ \cr -\+ acos(x) & any & $\cos^{-1} x$ (inverse cosine) in radians \cr -\+ arg(x) & complex & the phase of $x$ in radians\cr -\+ asin(x) & any & $\sin^{-1} x$ (inverse sin) in radians \cr -\+ atan(x) & any & $\tan^{-1} x$ (inverse tangent) in radians \cr -\+ besj0(x) & radians & $j_{0}$ Bessel function of $x$ \cr -\+ besj1(x) & radians & $j_{1}$ Bessel function of $x$ \cr -\+ besy0(x) & radians & $y_{0}$ Bessel function of $x$ \cr -\+ besy1(x) & radians & $y_{1}$ Bessel function of $x$ \cr -\+ ceil(x) & any & $\lceil x \rceil$, smallest integer not less than $x$ -(real part) \cr -\+ cos(x) & radians & $\cos x$, cosine of $x$ \cr -\+ cosh(x) & radians & $\cosh x$, hyperbolic cosine of $x$ \cr -\+ erf(x) & any & $\hbox{Erf}(\hbox{real}(x))$, error function of real($x$) \cr -\+ erfc(x) & any & $\hbox{Erfc}(\hbox{real}(x))$, 1.0 $-$ error function of real($x$) \cr -\+ exp(x) & any & $e^{x}$, exponential function of $x$ \cr -\+ floor(x) & any & $\lfloor x \rfloor$, largest integer not greater -than $x$ (real part) \cr -\+ gamma(x) & any & $\hbox{Gamma}(\hbox{real}(x))$, gamma function of real($x$) \cr -\+ ibeta(p,q,x) & any & $\hbox{Ibeta}(\hbox{real}(p,q,x))$, ibeta function of real($p$,$q$,$x$) \cr -\+ igamma(a,x) & any & $\hbox{Igamma}(\hbox{real}(a,x))$, igamma function of real($a$,$x$) \cr -\+ imag(x) & complex & imaginary part of $x$ as a real number \cr -\+ int(x) & real & integer part of $x$, truncated toward zero \cr -\+ lgamma(x) & any & $\hbox{Lgamma}(\hbox{real}(x))$, lgamma function of real($x$) \cr -\+ log(x) & any & $\log_{e} x$, natural logarithm (base $e$) of $x$ \cr -\+ log10(x) & any & $\log_{10} x$, logarithm (base $10$) of $x$ \cr -\+ rand(x) & any & $\hbox{Rand}(\hbox{real}(x))$, pseudo random number generator \cr -\+ real(x) & any & real part of $x$ \cr -\+ sgn(x) & any & 1 if $x>0$, -1 if $x<0$, 0 if $x=0$. imag($x$) ignored \cr -\+ sin(x) & radians & $\sin x$, sine of $x$ \cr -\+ sinh(x) & radians & $\sinh x$, hyperbolic sine $x$ \cr -\+ sqrt(x) & any & $\sqrt{x}$, square root of $x$ \cr -\+ tan(x) & radians & $\tan x$, tangent of $x$ \cr -\+ tanh(x) & radians & $\tanh x$, hyperbolic tangent of $x$\cr -\hrule % \hline -} - -%\end{tabular} -%\end{center} - -\section{Operators} -The operators in gnuplot are the same as the corresponding operators -in the C programming language, except that all operators accept -integer, real, and complex arguments, unless otherwise noted. -The ** operator (exponentiation) is supported, as in FORTRAN. - -Parentheses may be used to change order of evaluation. - - - -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% -\bye -\subsubsection{Binary} -The following is a list of all the binary operators and their -usages: - - -\begin{center} -\begin{tabular}{|ccl|} \hline -\multicolumn{3}{|c|}{Binary Operators} \\ -Symbol & Example & Explanation \\ \hline -\verb~**~ & \verb~a**b~ & exponentiation\\ -\verb~*~ & \verb~a*b~ & multiplication\\ -\verb~/~ & \verb~a/b~ & division\\ -\verb~%~ & \verb~a%b~ & * modulo\\ -\verb~+~ & \verb~a+b~ & addition\\ -\verb~-~ & \verb~a-b~ & subtraction\\ -\verb~==~ & \verb~a==b~ & equality\\ -\verb~!=~ & \verb~a!=b~ & inequality\\ -\verb~&~ & \verb~a&b~ & * bitwise AND\\ -\verb~^~ & \verb~a^b~ & * bitwise exclusive OR\\ -\verb~|~ & \verb~a|b~ & * bitwise inclusive OR\\ -\verb~&&~ & \verb~a&&b~ & * logical AND\\ -\verb~||~ & \verb~a||b~ & * logical OR\\ -\verb~?:~ & \verb~a?b:c~ & * ternary operation\\ -\hline -\end{tabular} -\end{center} -(*) Starred explanations indicate that the operator requires -integer arguments. - -Logical AND (\&\&) and OR ($|$$|$) short-circuit the way they do in C. -That is, the second \&\& operand is not evaluated if the first is -false; the second $|$$|$ operand is not evaluated if the first is true. - -The ternary operator evaluates its first argument (a).

You are welcome to download the source code. - - -\subsection{How did it come about and why is it called \gnuplot?} - -The authors of \gnuplot are: -Thomas Williams, Colin Kelley, Russell Lang, Dave Kotz, John -Campbell, Gershon Elber, Alexander Woo and many others. - -The following quote comes from Thomas Williams: -\begin{quote} - I was taking a differential equation class and Colin was taking - Electromagnetics, we both thought it'd be helpful to visualize the - mathematics behind them. We were both working as sys admin for an - EE VLSI lab, so we had the graphics terminals and the time to do - some coding. The posting was better received than we expected, and - prompted us to add some, albeit lame, support for file data. - - Any reference to GNUplot is incorrect. The real name of the program - is "gnuplot". You see people use "Gnuplot" quite a bit because many - of us have an aversion to starting a sentence with a lower case - letter, even in the case of proper nouns and titles. gnuplot is not - related to the GNU project or the FSF in any but the most - peripheral sense. Our software was designed completely - independently and the name "gnuplot" was actually a compromise. I - wanted to call it "llamaplot" and Colin wanted to call it "nplot." - We agreed that "newplot" was acceptable but, we then discovered - that there was an absolutely ghastly pascal program of that name - that the Computer Science Dept.\ occasionally used. I decided that - "gnuplot" would make a nice pun and after a fashion Colin agreed. -\end{quote} - - -\subsection{What does \gnuplot offer?} - -\begin{itemize} -\item Two-dimensional functions and data plots combining many different - elements such as points, lines, error bars, filled shapes, labels, arrows, ... -\item Polar axes, log-scaled axes, general nonlinear axis mapping, parametric coordinates -\item Data representations such as heat maps, beeswarm plots, violin plots, histograms, ... -\item Three-dimensional plots of data points, lines, and surfaces in -many different styles (contour plot, mesh) -\item Algebraic computation using integer, floating point, or complex arithmetic -\item Data-driven model fitting using Marquardt-Levenberg minimization -\item Support for a large number of operating systems, graphics - file formats and output devices -\item Extensive on-line help -\item \TeX{}-like text formatting for labels, titles, axes, data points -\item Interactive command line editing and history -\end{itemize} - - -\subsection{Is \gnuplot suitable for scripting?} - -Yes. Gnuplot can read in files containing additional commands during -an interactive session, or it can be run in batch mode by piping a -pre-existing file or a stream of commands to stdin. Gnuplot is used -as a back-end graphics driver by higher-level mathematical packages -such as Octave and can easily be wrapped in a cgi script for use as a -web-driven plot generator. Gnuplot supports context- or data-driven -flow control and iteration using familiar statements -{\em if else continue break while for}. - - -\subsection{Can I run \gnuplot on my computer?} - -\Gnuplot{} is in widespread use on many platforms, including -MS Windows, linux, unix, and OSX. The current source code retains -supports for older systems as well, including VMS, Ultrix, OS/2, and -MS-DOS. However 16-bit platforms are no longer supported. - -You should be able to compile the \gnuplot source more or -less out of the box in any reasonably standard (ANSI/ISO C, POSIX) -environment. - - -\subsection{Legalities} - -\Gnuplot{} is authored by a collection of volunteers, who cannot -make any legal statement about the compliance or non-compliance of -\gnuplot or its uses. There is no warranty whatsoever. Use at your own risk. - -\Gnuplot{} is freeware in the sense that you don't have to pay for it. -You can use or modify gnuplot as you like, however certain restrictions -apply to further distribution of modified versions. -Please read and abide by the modification and redistribution terms in -the \textit{Copyright} file. Some individual source files are explicitly -dual-licensed; in those cases alternative terms for redistribution of code -in that specific file are listed at the head of the file. - -\subsection{Does \gnuplot have anything to do with the FSF and the GNU -project?} - -\Gnuplot{} is neither written nor maintained by the FSF. At one time it -was distributed by the FSF but this is no longer true. \Gnuplot{} as a whole -is not covered by the GNU General Public License (GPL). - - -\subsection{Where do I get further information?} - -See the main gnuplot web page \http{www.gnuplot.info}. - -Some documentation and tutorials are available in other languages than English. -See \http{gnuplot.sourceforge.net/help.html}, section "Localized learning pages -about gnuplot", for the most up-to-date list. - - -\section{Setting it up} - -\subsection{What is the current version of \gnuplot?} - -The current stable version of \gnuplot is 5.4, first released in July 2020. -Incremental versions (patchlevel 1, 2, ...) are typically released every six months. -The development version of \gnuplot is currently 5.5. - -\subsection{Where can I get \gnuplot?} -\label{where-get-gnuplot} - -The best place to start is \http{www.gnuplot.info}. From there -you find various pointers to other sites, including the project -development site on SourceForge \http{sourceforge.net/projects/gnuplot}. - -The source distribution ("gnuplot-5.4.0.tar.gz" or a similar name) is -available from the official distribution site \http{sourceforge.net/projects/gnuplot}. - -\subsection{Why would I care about the development version?} - -The current development version will generally include features that are -not yet part of the most recent stable release of gnuplot. -%As of July 2020 the 5.5 development version notably supports -%\begin{itemize}{}{} -%\setlength\itemsep{-4pt} -%\item named colormaps to supplement the primary palette -%\item along-path smoothing options for 2D and 3D curves -%\end{itemize} - -\subsection{Where can I get current development version of \gnuplot?} - -The development version of gnuplot is held in a git repository which you -can clone as shown below to inspect or build an executable program -from the source. - -\scriptsize -\begin{verbatim} - git clone https://git.code.sf.net/p/gnuplot/gnuplot-main gnuplot -\end{verbatim} -\normalsize - -Questions related to the development version should go to -\mailto{gnuplot-beta@lists.sourceforge.net}. - - -\subsection{How do I compile \gnuplot on my system?} - -Read the release notes and files \textit{README} and \textit{INSTALL}. -You will need C and C++ compilers and installed versions of various -support libraries depending on what configuration options you choose and what -terminal types you want your executable to support. - -\begin{itemize} -\item -To build from a release version on linux, use \textit{./configure} (or \textit{./configure {-}{-}prefix=\$HOME/usr} -for an installation for a single user), \textit{make} and finally -\textit{make install}. Pay close attention to the output from the \textit{configure} -script (yes there is a lot of it). -There you will find hints as to what additional support libraries may be needed and -what additional options may be desirable. In general you will need to have installed -the "development" package for each of the support libraries. -\item -To build from the development source on linux you must run a separate script \textit{./prepare} -prior to running \textit{./configure} . -\item -On Windows, makefiles can be found in \textit{config/mingw}, \textit{config/msvc}, -\textit{config/watcom}, and \textit{config/cygwin}. Update the options in the -makefile's header and run the appropriate \textit{make} tool in the same directory -as the makefile. Additional instructions can be found in the makefiles. -\item -For other platforms, copy the relevant makefile (e.g. \textit{makefile.os2} for -OS/2) from \textit{config/} to \textit{src/}, optionally update options in the -makefile's header, then change directory to \textit{src} and run \textit{make}. -\end{itemize} - - -\subsection{What documentation is there, and how do I get it?} - -Full documentation is included in the release distribution as a PDF file. -Individual sections can be browsed from inside a gnuplot session -by typing \textit{help {\em keyword}}. -Documentation in other formats can be compiled from source in the -{\em docs} subdirectory. - -Online copies in English and Japanese are available at -\http{gnuplot.sourceforge.net/documentation.html}. - -\subsection{Worked examples} - -There is a directory of worked examples in the the source distribution. -These examples and the resulting plots may also be found online at -\http{gnuplot.sourceforge.net/demo/}. - - -\subsection{How do I determine which options were compiled into my \gnuplot executable?} - -Given that you have a compiled version of \gnuplot, you can use the -{\em show} command to display a list of configuration and build options -that were used to build your copy. The output formats (a.k.a. "terminals") -built into your copy of gnuplot are reported by {\em set terminal}. - -\small -\begin{verbatim} -gnuplot> show version long -gnuplot> set terminal -\end{verbatim} -\normalsize - - -\section{Working with it.} - -\subsection{How do I get help?} - -Give the {\em help} command at the initial prompt. After that, keep -looking through the keywords. Good starting points are {\em help plot} -and {\em help set}. - -\begin{itemize} -\item -Read the manual, if you have it. - -\item -Run the demos in the {\em demo} subdirectory or look at the -online copies. They should give you some ideas. -\http{gnuplot.info/demo} - -\item -Ask your colleagues, the system administrator, or the person who -set up \gnuplot. - -\item -There is an old-school usenet group devoted to gnuplot questions -\news{comp.graphics.apps.gnuplot} -inhabited mostly by users who found it last century. - -\item -A more browser-oriented help forum may be found on StackOverflow -\http{stackoverflow.com/questions/tagged/gnuplot} - -\item -If all these fail, send mail to the gatewayed mailing list -\mailto{gnuplot-info@lists.sourceforge.net}. -Please note that to reduce the amount of spam it would otherwise receive, -you must subscribe before you can post to it. Subscription instructions -may be found at -\http{lists.sourceforge.net/lists/listinfo/gnuplot-info}. - -\end{itemize} -When asking a question, always mention the \gnuplot version and -operating system you are using. If you are asking about a plot that -did not come out the way you expected, please try to show a minimal -set gnuplot commands that produce a plot showing the problem. - - -\subsection{How do I print out my graphs?} - -The output format produced by a plot command is determined by a -prior {\em set terminal} command. For non-interactive output -you should pair this with a {\em set output} command to provide -a file name. - -As an example, the following session first plots a graph of sin(x) to the -screen and then redraws that same plot as a PDF output file. -Note: the PDF plot may not look exactly like the plot on the screen. - -\small -\begin{verbatim} -gnuplot> plot sin(x) -gnuplot> set terminal pdf -Terminal type is now 'pdfcairo' -Options are ' transparent enhanced fontscale 0.5 size 5.00in, 3.00in ' -gnuplot> set output "sin.pdf" -gnuplot> replot -gnuplot> unset output # close output file (otherwise it stays open) -gnuplot> unset terminal # return to default interactive terminal -gnuplot> -\end{verbatim} -\normalsize - -If the start point is not the default interactive terminal you -can accomplish the same thing using {\em push} and {\em pop} -\small -\begin{verbatim} -gnuplot> set terminal push # save current terminal type (may not be default) -gnuplot> set terminal pdf -gnuplot> set out 'a.pdf' -gnuplot> replot -gnuplot> unset out -gnuplot> set term pop # restore saved terminal type -\end{verbatim} -\normalsize - -Some interactive terminal types ({\em win, wxt, qt}) provide a printer icon -on their toolbar. This widget prints the current plot or saves it to file -using generic system tools rather than by using a different gnuplot terminal type. -That is, the file you get by selecting "save to png" in the print menu may be -different than the file you get from {\em set term png; replot;}. -In general a plot saved in this way will more closely reproduce the screen image than -a plot generated from the command line by changing the terminal type. - - -\subsection{How do I include my graphs in my favorite word processor?} - -Basically, you save your plot to a file in a format your word processor -can understand, and then you read in the plot from your word processor. Vector -formats (PostScript, emf, svg, pdf, \TeX{}, \LaTeX{}) should be preferred, -as you can scale your graph later to the right size. - -Use {\em set term} to get a list of available file formats. - -Many word processors can use Encapsulated PostScript (*.eps) for graphs. -You can generate eps output in \gnuplot using either -{\em set terminal postscript eps} -or -{\em set terminal epscairo} -. -\Gnuplot does not embed a bitmap preview image in the output eps file. -To accommodate some word processors you may have to add a preview image yourself -using an external tool before importing it into the word processor. - -Some applications, including the LibreOffice and Microsoft Office suites, -can handle vector images in EMF format. These can be either produced by the emf -terminal, or by selecting 'Save as EMF...' from the toolbar of the -windows terminal plot window. - -LibreOffice can also read SVG, as well as AutoCAD's dxf format. - -There are many ways to use gnuplot to produce graphs for inclusion in a -\TeX\ or \LaTeX\ document. -Some terminals produce *.tex fragments for direct inclusion; others -produce *.eps, *.pdf, *.png output to be included using the -\textbackslash{}includegraphics command. -The epslatex and cairolatex terminals produce both a graphics -file (*.eps or *.pdf) and a *.tex document file that refers to it. -The tikz terminal produces full text and graphics to a pdf file -when the output is processed with pdflatex. - -Most word processors can import bitmap images (png, pbm, etc). -The disadvantage of this approach is that the resolution of your -plot is limited by the size of the plot at the time it is generated -by \gnuplot, which is generally a much lower resolution than the -document will eventually be printed in. - - -\subsection{How do I edit or post-process a \gnuplot graph?} - -This depends on the terminal type you use. - -\begin{itemize} - -\item \textbf{svg} terminal (scalable vector graphics) output can -be further edited by a svg editor, e.g. -\textbf{Inkscape} (\http{www.inkscape.org}), -\textbf{Skencil} (\http{www.skencil.org}) or -\textbf{Dia} (\http{projects.gnome.org/dia/}), or loaded -into \textbf{OpenOffice.org} with an on-fly conversion into OO.o Draw -primitives. - -\item PostScript or PDF output can be edited directly by tools such -as Adobe Illustrator or Acrobat, or can be converted to a variety -of other editable vector formats by the \textbf{pstoedit} package. -Pstoedit is available at \http{www.pstoedit.net}. - -\item The DXF format is the AutoCAD's format, editable by several -other applications. - -\item Bitmapped graphics (e.g. png, jpeg, pbm) can be edited using -tools such as ImageMagick or Gimp. -In general, you should use a vector graphics program to post-process -vector graphic formats, and a pixel-based editing program -to post-process pixel graphics. - -\end{itemize} - -\subsection{How do I save and restore my current settings?} - -Use the {\em save "filename"} and {\em load "filename"} commands. - -\subsection{Can I put both commands and data into a single file?} - -\Gnuplot version 5 supports named blocks of data in "here document" format: -\small -\begin{verbatim} -gnuplot> $DATABLOCK << EOD - cats 4 2 - dogs 1 4 -EOD -gnuplot> plot $DATABLOCK using 2:3:1 with labels -\end{verbatim} -\normalsize -Once the named block has been defined, it can be used as many times -as you like. - -Data can also be provided in-line as part of a plot command using the -pseudo-file "-". In this case the data can only be used once. - -\small -\begin{verbatim} -gnuplot> plot "-" -1 1 -2 4 -3 9 -e -\end{verbatim} -\normalsize - -\subsection{How do I run my data through a filter before plotting?} - -If your operating system supports the popen() function, you -can filter input data through another program or system utility -as part of the {\em plot} command. - -\small -\begin{verbatim} -gnuplot> plot "< sort +2 file.in" # pre-sort data on column 2 -\end{verbatim} -\normalsize - -This mechanism is particularly powerful in combination with the -unix-derived command line utilities {\em awk}, {\em sort} and {\em grep}. - -\subsection{Can I use \gnuplot routines for my own programs?} - -On systems supporting pipes, you can pipe commands to \gnuplot from other -programs. Many applications with gnuplot as the graphics engine, like Octave -(\http{www.octave.org}), uses this method. This also works from a cgi script to -drive \gnuplot from a forms-based web page. - - -\section{Customizing the appearance of your plot} - -\subsection{How to inspect or change the default colors, line, and point properties?} - -When you issue a {\em plot} or {\em splot} command with multiple components, -\gnuplot will by default cycle through a set of colors and linetypes. -You can override this by providing specific color or linetype properties in the -plot command or you can change the default sequence. -Each of the commands below accepts many additional parameters -\begin{list}{}{} - \item - {\em test} displays the active colors, line and point properties, etc - for the current terminal type - \item - {\em set color} or {\em set monochrome} selects a pre-defined sequence. - \item - {\em set linetype} changes the properties of an existing linetype or adds a new one. - \item - {\em set palette} changes the color palette used for pm3d modes such as heat maps. - \item - {\em set pointsize} scales all points by an additional factor -\end{list} - -\subsection{Hidden line or surface removal} - -There are two relevant commands. {\em set hidden3d} affects surfaces -drawn using the 3D plot style {\em splot ... with lines}.

If you want to draw a line -through every point but only draw a point symbol at every nth point, -then try {\em plot 'a.dat' with linespoints pointinterval n}. - - -\subsection{How do I plot a vertical line?} - -Depending on context, the main methods are: -\begin{itemize} -\item {\em set arrow .... .... nohead} where you have to compute -explicitly the start and the end of the arrow. -\item generate inlined datapoints and plot them -\end{itemize} - -\subsection{Y axis label in the wrong place and/or left margin too big} -\Gnuplot has trouble estimating how much space to the left of the plot -will be required to hold the Y axis label if it is printed horizontally -({\em set ylabel norotate}). This is particularly true if there is -TeX markup in the label string. To work around this problem you can place -the text in a numbered label rather than in {\em ylabel}. -\small -\begin{verbatim} -Y = 1001 -set label Y '$\operatorname{\mathfrak{Im}} S_{21}$' -set label Y norotate at graph 0.0, 0.5 offset -6 -\end{verbatim} -\normalsize - -\section{Plot types that people often ask about} - -\subsection{Animations} - -\Gnuplot versions through release 5.4 support only one terminal type -(gif) that directly outputs an animated file: -\begin{verbatim} -set terminal gif animate {delay <time>} {loop <N>} {optimize} -\end{verbatim} - -The development version (5.5) also supports animation in webp format. -Have a look at -\http{gnuplot.sourceforge.net/demo/animate2.html} -in the demo collection. - -\subsection{Implicit defined graphs} - -Implicit graphs or curves cannot be plotted directly in \gnuplot. -However there is a workaround. -\small -\begin{verbatim} -gnuplot> # An example.

It also offers a few options for accumulating raw data -into bins, which can in turn be displayed as a bar chart. See the documentation -for \textit{bins} and for \textit{smooth frequency}. - -\subsection{Does \gnuplot support pie charts? quarterly time charts?} - -Pie charts are sort of difficult in \gnuplot, but see -\http{gnuplot.sourceforge.net/demo/circles.html}, -or have a look at -\http{gnuplot-tricks.blogspot.com/2009/08/pie-charts-entirely-in-gnuplot.html}. - -The demo collection contains an example of a simple Gantt chart. - -\subsection{Does \gnuplot support multiple y-axes on a single plot?} - -Yes. 2D plots can have separate x axes at the bottom (x1) and top (x2), -and separate y axes at the left (y1) and right (y2). Version 5 offers a -plot mode \textit{with parallelaxes} that allows any number of additional -y axes to be defined. - -\subsection{How to draw a solid made of triangular facets?} - -Version 5.4: plot style \textit{with polygons} can handle polygonal faces -(triangles, rectangles, octagons, ...) in either 2D or 3D plots. - -In older versions the best you can do is to describe colored quadrangles -that are facets of a 3D object using a file organized like this: -\small -\begin{verbatim} -# triangle 1 -x0 y0 z0 <c0> -x1 y1 z1 <c1> - -x2 y2 z2 <c2> -x2 y2 z2 <c2> - - -# triangle 2 -x y z -... -\end{verbatim} -\normalsize - -Notice the single and double blank lines.

Or you can use octal escape sequences to type them in -byte-by-byte, or (version 5.4) unicode escape sequences like -{\em \verb&\U+221E&} ($\infty$). -If your keyboard does generate UTF-8 but you don't know what keystrokes would -produce a specific character, there are probably suitable character selection -apps for your desktop (e.g. KDE {\em kcharselect} or GNOME {\em Character Map}). - -\subsection{What if I need h-bar (Planck's constant)?} - -The most straightforward way is to use a UTF-8 font, and type in the -$\hbar$ character (Unicode {\verb&\U+210F&}) directly. - -PostScript: PostScript does not handle utf8 easily so you must use an -approximation based on enhanced text markup and possibly a special -Symbol font: - -\verb+ @{/=56 -} {/=24 h}+ or -\verb+ {/=8 @{/Symbol=24 -} _{/=14 h}}+ -In the latter, the "-" (a long one in /Symbol) is non-spacing and 24-pt. -The 14-pt "h" is offset by an 8-pt space (which is the space preceding -the "\_") but smaller, since it's written as a subscript. -But these don't look too much like the hbar we're used to, since the bar -is horizontal instead of sloped. -Another possibility is \verb+{/=14 @^{/Symbol=10 -}{/=14 h}}+. - -The reduced Planck's constant can be set very easily by using the -AMS-LaTeX PostScript fonts which are available from -\http{www.ams.org/tex/amsfonts.html} (also included in many LaTeX -distributions). \Gnuplot{} (see \verb+help fontpath+) and the -PostScript interpreter (usually Ghostscript) have to know where the -file \verb+ msbm10.pfb+ (or \verb+ msbm10.pfa+) resides. Use -\verb+ {/MSBM10 \175}+ to produce \verb+ \hslash+ which is a "h" -superimposed by a sloped bar. The standard \verb+ \hbar+ (horizontal -bar) has the octal code 176. Please note that h-bar exists only as an -italic type. - -\subsection{What if I need the Solar mass symbol?} - -As with Planck's constant, the most straightforward way is to use a -UTF-8 font, and type in the $\odot$ character -(Unicode {\verb&\U+2299&} ; "circled dot operator") -directly. The very similar glyph at (Unicode code point {\verb&\U+2609&} ; "sun") -may be even better, but not many fonts provide it. - -\subsection{How to use Greek letters or other special symbols?} - -The old-style way is to use enhanced text mode to switch to a specialize font, -e.g. the Adobe "Symbol" font, that maps the characters you want onto ascii -letters 'a', 'b', etc. This may still be necessary for PostScript output. -However a much simpler way is to select UTF-8 encoding and enter the -special characters just as you would any other text. -This obviates the need to change fonts and gives you access to all unicode -code points including CJK character sets. To actually print or view the -files produced by \gnuplot you still need appropriate fonts installed on -your computer or output device. \Gnuplot itself does not provide fonts. - -The various \LaTeX{} terminal types (\textit{latex, epslatex, tikz, context, cairolatex}) -hand off text generation to \LaTeX{}. In this case you can use normal \LaTeX{} -markup like \verb+$\alpha_{3}$+ . - -\subsection{How do I include accented characters?} - -If you are stuck using a non-utf8 encoding you should use -8-bit character codes together with the appropriate encoding option -to obtain accented characters like \"u or \^n in your labels. -You can represent the 8-bit code with an escape sequence. -See the following example: - -\small -\begin{verbatim} -gnuplot> set encoding iso_8859_1 -gnuplot> set title "M\374nchner Bierverbrauch \374ber die Jahre" -gnuplot> plot "bier.dat" u 1:2 -\end{verbatim} -\normalsize - -Everyone else should use UTF-8, where these are normal characters. - -\subsection{Can I put different text sizes into my plots?} - -Most terminal types allow you to specify a starting font face and size. -The "enhanced text" mode allows you to change fonts, text sizes, bold and -italic styles within a plot. - - - -\section{Miscellaneous} - -\subsection{Does \gnuplot support a driver for graphics format XXX?} - -To see a list of the available graphic drivers for your installation of -\gnuplot, type {\em set term}. - -Some graphics drivers are included in the source distribution -but are not built by default. If you want to use them, you'll -have to recompile from source. - -\subsection{I've found a bug, what do I do?} - -First, try to see whether it actually is a bug, or whether it -is a feature you can turn off with some obscure {\em set} command. - -Next, see whether you have an old version of \gnuplot; if so, -chances are the bug has been fixed in a newer release. - -Before submitting a bug report, please check whether the bug in question -has already been fixed in the upstream source since the release of the -current version. These are marked "pending-fixed" on the bug tracker. - -If, after checking these things, you still are convinced that there is a -bug please report it using the bug-tracker at -\http{sourceforge.net/p/gnuplot/bugs}. -Be sure to include the version of \gnuplot (including patchlevel) and -the operating system you are running it on. -It helps a lot if you can provide a simple script that reproduces the error. - -The tracker on sourceforge is for reporting bugs and collecting bug fixes -that will appear in a subsequent release. -The various online forums are better places to ask about -work arounds or actually solving \gnuplot related problems. - -\subsection{Can I do heavy-duty data processing with \gnuplot? or -What is beyond \gnuplot?} - -\gnuplot by itself is not very well suited for heavy numerical computation. -On the other hand it can easily handle very large data sets (millions of points). -If you have a specific application where the limitation is gnuplot's speed in -evaluating a non-trivial function, it might be worth coding this function in -C or C++ and making it a loadable plugin that gnuplot can call. - -Programs you might look into if you need intensive numerical computation: - -\textbf{octave} (\http{www.octave.org}) -is a high-level language primarily intended for numerical computations. -Octave is licensed under GPL, and in principle, it is a free Matlab clone. -It provides a convenient command line interface for solving linear and nonlinear problems -numerically. By the way, octave uses \gnuplot as its plotting -engine, so you get a data-processing program on top of \gnuplot. - -\textbf{scilab} (\http{www.scilab.org}) is another open source alternative to \textbf{matlab}. - -\textbf{julia + Gaston} (\http{github.com/mbaz/Gaston.jl}) -The Julia language is designed for numerical analysis and computational science. -Gaston is a julia package that provides an interface to gnuplot for graphical output. - -\subsection{What if I need special function that gnuplot doesn't have?} - -See above. You may have to use another program or write a custom plugin. - - -\subsection{How to use hotkeys in my interactive terminals} - -Most of the interactive terminals support both pre-defined and user-defined -hotkeys to replot, toggle plot elements, change axis scaling, and so on. -Hit \textit{h} in an active gnuplot plot window to get list of hotkeys. -Read \textit{help mouse} and \textit{help bind} for more information. - - -\subsection{I want to help in developing the next version of \gnuplot. -What can I do?} - -Join the \gnuplot beta test mailing list by sending a mail -containing the line -\verb+subscribe gnuplot-beta+ -in the body (not the subject) of the mail to -\mailto{Majordomo@lists.sourceforge.net}. - - -\section{Common problems} - - -\subsection{Help! None of my fonts work.} - -Gnuplot does not do font handling by itself; it must necessarily leave -that to the individual device support libraries. Unfortunately, this -means that different terminal types need different help in finding -fonts. Here are some quick hints. For more detailed information please -see the gnuplot documentation for the specific terminal type you are -having problems with. - -\begin{description} -\item [{png/jpeg/gif}] These terminal types use the libgd support library, which -searches for fonts in the directories given in the environmental variable -GDFONTPATH. Once you get libgd fontpaths sorted out, you will probably -want to set a default font for gnuplot. -For example: \verb+setenv GNUPLOT_DEFAULT_GDFONT verdana+ -\item [{post}] PostScript font names are not resolved until the document -is printed. Gnuplot does not know what fonts are available to your -printer, so it will accept any font name you give it. However, it -is possible to bundle a font with the gnuplot output; please see the -instructions given by gnuplot's internal command {}``help set term -post fontfile''. -\item [{svg}] Font handling is viewer-dependent. -\item [{x11}] The x11 terminal uses the normal x11 font server mechanism. -The only tricky bit is that in order to use multi-byte fonts you must -explicitly say so: -\small\begin{verbatim} -set term x11 font "mbfont:sazanami mincho,vera,20" -\end{verbatim}\normalsize -\item [{win}] Select "Choose font..." from the "Options" pull-down menu -in the toolbar. -\item [{wxt, qt}] On linux systems these terminals rely on fonts provided -by the system's \textit{fontconfig} utility. -\end{description} - -\subsection{The first plot in a qt terminal session fails or has bad layout} - -You may also get an error message about "slow font initialization". -This is because qt relies on a shared system font cache. -If you request a font that no one else is using, it takes a while to -update the cache. This mostly happens on Windows or OSX, because other -programs on those systems tend to use a different font mechanism so the -relevant font cache may be empty. -Try invoking gnuplot with command line option {\em -\@-slow}. - -\subsection{Pm3d splot from a datafile does not draw anything} - -You do {\em set pm3d; splot 'a.dat'} and no plot but colorbox appears. -Perhaps there is no blank line in between two subsequent scans (isolines) in -the data file? Add blank lines! If you are curious what this means, then don't -hesitate to look to files like {\em demo/glass.dat} or {\em demo/triangle.dat} -in the gnuplot demo directory. - -You can find useful the following awk script (call it e.g. {\em addblanks.awk}) -which adds blank lines to a data file whenever number in the first column -changes: -\small -\begin{verbatim} -/^[[:blank:]]*#/ {next} # ignore comments (lines starting with #) -NF < 3 {next} # ignore lines which don't have at least 3 columns -$1 != prev {printf "\n"; prev=$1} # print blank line -{print} # print the line -\end{verbatim} -\normalsize - -Then, either preprocess your data file by command -{\em awk -f addblanks.awk <a.dat} -or plot the datafile under a unixish platform by\\ -{\em gnuplot > splot "<awk -f addblanks.awk a.dat"}. - -\subsection{Why does \gnuplot ignore my very small numbers?} - -For some purposes \Gnuplot{} treats numbers less than 1.e-08 as being zero. -Thus if you are trying to plot a collection of very small numbers, -they may be plotted as zero. Worse, if you're plotting -on a log scale, they will be off scale. Or, if the whole set of -numbers is "zero", your range may be considered empty: - -\small -\begin{verbatim} -gnuplot> plot 'test1' -Warning: empty y range [4.047e-19:3e-11], adjusting to [-1:1] -gnuplot> set yrange [4e-19 : 3e-11] -gnuplot> plot 'test1' - ^ -y range is less than `zero` -\end{verbatim} -\normalsize - -The solution is to change gnuplot's idea of "zero": -\small -\begin{verbatim} -gnuplot> set zero 1e-20 -\end{verbatim} -\normalsize - -For more information, type {\em help set zero}. - -\subsection{When I {\em replot} or {\em resize} a multiplot I get only a fragment} - -\Gnuplot only retains enough information to regenerate the most recent -{\em plot} or {\em splot} command. -In order to reproduce the entire multiplot you need to save the complete -sequence of commands that generated it into a script file. -Then you can {\em load} that script into \gnuplot as many times as you need -for replotting the drawing to different terminals or output files. - -The same problem arises when you resize a multiplot displayed in an interactive -terminal window, because the resize event normally triggers a replot. -The {\em qt} and {\em wxt} terminals provide a toggle in the toolbox widget -that suppresses this replot on resize. The {\em x11} terminal provides a -terminal option {\em set term x11 noreplotonresize}. - -\subsection{My formulas (like 1/3) are giving me nonsense results! What's going on?} - -\Gnuplot{} does integer, and not floating point, arithmetic on -integer expressions. For example, the expression 1/3 evaluates -to zero. If you want floating point expressions, supply -trailing dots for your floating point numbers. Example: - - -\small -\begin{verbatim} -gnuplot> print 1/3 - 0 -gnuplot> print 1./3. - 0.333333 -\end{verbatim} -\normalsize - -This way of evaluating integer expressions is shared by both C and Fortran. - - -\subsection{My output files are incomplete!} - -You may need to flush the output and close the file with -{\em set output} or {\em unset output}). - -Some output formats (postscript, pdf, latex, ...) can include several -pages of plots in a single output file.

The plot could then be included in a -\LaTeX\ document. I added a number of embellishments, supported only -by the {\tt latex} terminal, allowing the user to produce -publication-quality plots. - -In late 1989 and early 1990 Gnu\TeX\ and a number of other gnuplot -variants were merged together into a new release of gnuplot, 2.0. This -includes, among many other improvements, a \LaTeX\ driver derived from -the one in Gnu\TeX. -Anyone interested in using gnuplot with \LaTeX\ should read the next -section, a tutorial, and the primary gnuplot manual. - -The reader should note that the \LaTeX\ picture environments output by -gnuplot can be quite large and complicated, and can easily exceed the -memory capacity of \TeX. If an enlarged version of \TeX\ is available, -it is wise to use it. Otherwise, keep your plots simple and add -\verb+\clearpage+ to your document where necessary. - -There is also an EEPIC driver ({\tt eepic}), intended for use with -the EEPIC macro package for \LaTeX. EEPIC allows for much more -efficient line-drawing, runs through \LaTeX\ faster, and uses less -memory. See Section~\ref{s:eepic} for more information. - -Other gnuplot terminal types have been added that take advantage of -newer \TeX\ and \LaTeX\ packages and variants, including {\tt emtex}, -{\tt metafont}, {\tt epslatex}, {\tt tikz}, and {\tt context}. - -\section{Using gnuplot for \LaTeX: a Tutorial} - -Gnuplot is by nature an interactive program. Users making plots for -\LaTeX\ will generally not use gnuplot interactively. Whenever hard -copy is desired from gnuplot, the program need not be run on a -graphics terminal. In this case the output is directed to a file or -pipe, then sent to the appropriate output device. - -We now ignore the interactive nature of gnuplot and provide the input -to gnuplot from a file, \ie, -\begin{verbatim} - gnuplot plotcommands.gp -\end{verbatim} -In this example, all of the commands to gnuplot are contained in the -file {\tt plotcommands.gp}. Multiple filenames may be supplied to gnuplot -this way, read in the order they are given. The output (one or more -plots) may be piped to another program or redirected to a file. -Usually, however, we direct the output explicitly with an instruction -to gnuplot (the {\tt set output "outfile.tex"} command). Gnuplot continues to -print error messages to the terminal (stderr). After printing, the output file -has to be closed by {\tt set output}, \ie{} without the file name specification. - -\paragraph{Example 1:} Here is a first example, producing a plot for -this document. The gnuplot input file is given below, and the output -appears as Figure~\ref{eg1}. The input file defines the output to be -in \LaTeX, gives a file name for the output, and plots $y=\sin(x)$ for -$x$ on $[-\pi,\pi]$. To produce the figure, I simply -\verb+\input{eg1}+ in a {\tt center} environment in a {\tt figure} -environment. In following examples, I will enclose the figure in a box -to make it look a little better. - -\singlespace -\begin{verbatim} - set terminal latex - set output "eg1.tex" - plot [-3.14:3.14] sin(x) -\end{verbatim} -\currentspace - -\begin{figure}[htbp] - \begin{center} - \input{eg1} - \end{center} - \caption{A first example: $y=\sin(x)$.} - \label{eg1} -\end{figure} - -Note that gnuplot has drawn in the axes, labeled the tic marks for us, -scaled the $y$ axis automatically, and added a key in the -upper-right-hand corner (this may be moved with the {\tt set key} -command, and removed with {\tt unset key}% -\footnote{In gnuplot version 4.0, the syntax {\tt set noXXX} changed to -{\tt unset XXX}.}). - -This is the default line style for the \LaTeX\ driver. Because of the -limited picture capabilities of \LaTeX, many dots are required to -approximate drawing a solid line. This may overload the memory of many -\TeX\ implementations. There are other line types available that draw -dotted lines and use much less memory. The EEPIC driver draws solid -lines with much less memory usage. - -\paragraph{Example 2:} Now we will embellish the plot a little with -some labels. This input file produces Figure~\ref{eg2}. - -\singlespace -\begin{verbatim} - set terminal latex size 7cm, 5cm - set output "eg2.tex" - set format xy "$%g$" - set title 'This is a plot of $y=\sin(x)$' - set xlabel 'This is the $x$ axis' - set ylabel 'This is\\the\\$y$ axis' - plot [0:6.28] [0:1] sin(x) -\end{verbatim} -\currentspace - -\begin{figure}[htbp] - \begin{center} - \input{eg2} - \end{center} - \caption{A fancier example.} - \label{eg2} -\end{figure} - -We have specified the plot to be 7 cm wide and 5 cm tall with -the {\tt set term latex size ...} command. This is the size of the -area used by the plot, {\em including} space for the labels. -In the first example, this size was the default 5 inches by 3 inches. - -We have requested that the format used by the $x$- and $y$-axis tic -mark labels be in \LaTeX\ math mode. This makes the labels look a -little better. The default is \verb+set format xy "%g"+. The \verb+%g+ -represents the general-purpose floating point formatting specification -for the {\tt printf} function in C. Any valid floating-point -formatting specification, or \LaTeX\ command, is allowed in the -format. - -A title for the plot and labels for the axes were set up in the next -three commands. Note that they are processed by \LaTeX\ and so may -have math mode and other symbols in them. The ylabel may have multiple -lines, delineated with \verb+\\+. The ylabel can be moved around with -optional offset parameters (see {\tt set ylabel} in the gnuplot -manual). Typically, the ylabel needs to be moved to the left to avoid -interfering with the left-hand side of the plot. Once these labels -are set up, they will be used for all subsequent plot commands until -they are changed. These labels are also supported by the other -terminal types, but (of course) any \LaTeX\ code in the string will -not be interpreted. We have also defined the range of both $x$ (now -$[0,2\pi]$) and $y$ (here $[0,1]$). - -So far we have plotted one curve, $y=\sin(x)$, on one plot. In -gnuplot, each {\tt plot} command generates a new plot. If the output -is to a screen, the screen is cleared. If to a printer, a new page is -produced. In the {\tt latex} case, a new picture is started. It is not -likely that \LaTeX\ users will want this to happen, so generally each -plot has its own input file and is kept in a separate output ({\tt -.tex}) file for inclusion at different places in the document. - -\paragraph{Example 3:} To place more than one curve on a plot, use one -{\tt plot} statement and separate the description of each curve by a -comma. In our next example, we will plot both a function and a data -file on the same plot. This plot is shown in Figure~\ref{eg3}. - -\singlespace -\begin{verbatim} - set terminal latex - set output "eg3.tex" - set format xy "$%g$" - set title "This is another plot" - set xlabel "$x$ axis" - set ylabel "$y$ axis" - set key at 15,-10 - plot x with lines, "eg3.dat" with linespoints -\end{verbatim} -\currentspace - -\boxfigure{htbp}{\fullboxwidth}{ - \begin{center} - \input{eg3} - \end{center} - \caption{An example with two curves on the same plot.} - \label{eg3} -} - -Here you will see that the $x$ range was not specified. The $x$ range -is determined automatically, unless specified by the user. In -this case, it is defined by the range of the data file -\verb+"eg3.dat"+. The function is plotted over the same range. If no -data files or $x$ range are supplied, the default range of $[-10:10]$ -is used. We have also moved the key to a different position. The -function $y=x$ is plotted ``with lines'', which is the default plot -style for functions, and is shown here to illustrate the plot style -option. The data file {\tt eg3.dat} is plotted with style {\tt -linespoints}, a style like {\tt lines} that also plots a symbol at -each data point. - -There is a style called {\tt points} that only plots the symbols at -data points, and another called {\tt dots} that plots a tiny dot for -each data point. The {\tt points} and {\tt linespoints} styles -produce a different point symbol for each curve on the plot (for up to -twelve symbols, after which they are re-used; see -Figure~\ref{testcomp} for a complete list). The {\tt lines} and {\tt -linespoints} styles use a different line style for each curve on the -plot (in this example the dots have different spacing). The -style {\tt impulses} draws a perpendicular from each point to the -$x$-axis. Finally, the {\tt errorbars} style can draw error bars at -each data point (see the gnuplot manual). - -\paragraph{Example 4:} In the above plots of $\sin(x)$, it would make -more sense to label the axis in units of $\pi$. The position and -labels of the tic labels may be specified by the user, with the {\tt -set xtics} and {\tt set ytics} commands. This is demonstrated by -the following example, shown in Figure~\ref{eg4}. - -\singlespace -\begin{verbatim} - set terminal latex - set output "eg4.tex" - set format y "$%g$" - set format x "$%.2f$" - set title 'This is $\sin(x)$' - set xlabel "This is the $x$ axis" - set ylabel "$\\sin(x)$" - unset key - set xtics -pi, pi/4 - plot [-pi:pi] [-1:1] sin(x) -\end{verbatim} -\currentspace - -\boxfigure{htbp}{\fullboxwidth}{ - \begin{center} - \input{eg4} - \end{center} - \caption{An example of the {\tt set xtics} command.} - \label{eg4} -} - -Since {\tt pi} is a predefined variable in gnuplot, we can use it -anywhere we may use an expression. The {\tt set xtics} command here -specifies that the tics on the $x$ axis start at $-\pi$ and increment -by $\pi/4$. Since no end point is given, the tics continue to the -right edge. We have also turned off the key, and changed the format to -restrict the $x$-axis tic labels to 2 decimal places. Note that the -y axis label was delimited by double quotes, so the -backslash had to be escaped. Within single quotes, as in the title, -gnuplot passes the backslashes through with no changes. -(The exception: a backslash at the end of a line---even within single -quotes---is used by gnuplot for line continuation.) - -With a little more work, the plot can look even better. Another form -of this command allows us to specify the label and position of each -tic individually. Replacing the above {\tt set xtics} command with -the following gives us Figure~\ref{eg5}. We also make use of the line -continuation character, the backslash (\verb+\+), to spread out this -command for readability. - -\singlespace -\begin{verbatim} - set xtics ('$-\pi$' -pi,\ - '$-\frac{\pi}{2}$' -pi/2,\ - "0" 0,\ - '$\frac{\pi}{2}$' pi/2,\ - '$\pi$' pi) -\end{verbatim} -\currentspace - -\boxfigure{htbp}{\fullboxwidth}{ - \begin{center} - \input{eg5} - \end{center} - \caption{A fancy example of the {\tt set xtics} command.} - \label{eg5} -} - -\paragraph{Going further:} You should now be able to make a variety of -plots for your \LaTeX\ document. We will present a final example -without explanation that showcases some of the capabilities of -gnuplot. You may find documentation for the various commands in the -gnuplot manual, though hopefully this example is somewhat -self-explanatory. This is shown in Figure~\ref{eg6}. - -\singlespace -\begin{verbatim} - set terminal latex size 5.0, 3.0 - set output "eg6.tex" - set format y "$%g$" - set format x '$%5.1f\mu$' - set title "This is a title" - set xlabel "This is the $x$ axis" - set ylabel 'This is\\a longer\\version\\ of\\the $y$\\ axis' offset -1 - set label "Data" at -5,-5 right - set arrow from -5,-5 to -3.3,-6.7 - set key top left - set xtic -10,5,10 - plot [-10:10] [-10:10] "eg3.dat" title "Data File" with linespoints lt 1 pt 7,\ - 3*exp(-x*x)+1 title '$3e^{-x^{2}}+1$' with lines lt 4 -\end{verbatim} -\currentspace - -\begin{figure} - \begin{center} - \input{eg6} - \end{center} - \caption{An example of many features.} - \label{eg6} -\end{figure} - -\paragraph{Line and point types:} For reference, we show all of the -line and point types available in Figure~\ref{testcomp}. - -\subsection{Summary --- Use with \LaTeX} -In summary, to use the most basic \LaTeX\ mode of gnuplot, the first -command to gnuplot should be -\begin{syntax} - set terminal latex -\end{syntax} -and the output of gnuplot should be directed to a file, for example, -\begin{verbatim} - set output "plot.tex" -\end{verbatim} -This may be anything you like but it should have a {\tt .tex} extension, -of course. The default plot size is 5 inches by 3 inches. -You can change this be specifying a size in either cm or inches when -you select the terminal -\begin{syntax} - set terminal latex size 7cm, 5cm -\end{syntax} - - -Then you do the (s)plot, and finally issue commands to close the file and -switch the terminal back to the default by -\begin{verbatim} - set output - set terminal pop -\end{verbatim} - -Finally, the file will contain all of the plots you have -specified (you probably only want one plot per file). This file can -then be used in a \LaTeX\ document, \eg, - -\singlespace -\begin{verbatim} - \begin {figure} - \begin{center} - \input{plot} - \end{center} - \end {figure} -\end{verbatim} -\currentspace -This puts the plot into a figure. - -You will also want to read about the following commands: {\tt set -title, set xlabel, set ylabel, set key, set label, set xtics, set -ytics}, and {\tt set clip}. These are all described in the regular -gnuplot manual. - -\section{Use with EEPIC} -\label{s:eepic} -EEPIC is a macro package extending the picture environment of \LaTeX. -If you have the EPIC or EEPIC macros, and your {\tt dvi} translator -supports the {\em tpic\/} \verb+\special+s, then you can save \LaTeX\ -memory. With EEPIC pictures, the {\tt plot.tex} file will be smaller, -\LaTeX\ will run much faster (and need much less memory), and the {\tt -dvi} file will be smaller. The quality of the output is about the -same. If you change the source, you can generate some more interesting -line styles. - -To use EEPIC, set gnuplot's terminal type to {\tt eepic} instead of -{\tt latex}, and use gnuplot as before. The line styles will change. -Include the file {\tt plot.tex} in your document as before, along with -the document style options {\tt [epic,eepic]}. - -\section{Other \TeX-based terminal types in gnuplot} - -In addition to the \texttt{latex} terminal, the following \LaTeX-friendly -terminals are available. The gnuplot documentation contains more information -about the options and usage for each of these. - -\begin{itemize} -\item \texttt{emtex}: Like the \texttt{latex} terminal, but supports emtex -specials: any line slopes contrary to a very limited set of \LaTeX{} slopes. - -\item \texttt{epslatex}: Combined \LaTeX{} and postscript parts for text and -lines, respectively, with the postscript part included by -\verb+\includegraphics{...}+ command. - -\item \texttt{pstex} and \texttt{pslatex}: Combined \TeX{} / \LaTeX{} and -postscript parts for text and lines, respectively, included by -\verb+\special{psfile=...}+ command. - -\item \texttt{mf} and \texttt{mp}: Produces metafont and metapost outputs. - -\item \texttt{pslatex and epslatex}: New versions of these terminals were -introduced in gnuplot 4.4. See the example below. - -\item \texttt{tikz}: Much improved graphics compaired to earlier \LaTeX terminals. -Use of the terminal requires a lua interpreter that is called by gnuplot. -The resulting .tex file can be processed using pdflatex. - -\item \texttt{context}: Produces output for the {Con{\TeX}t} environment. - -\end{itemize} - -The {\tt tikz} and {\tt context} terminals support newer gnuplot features -such as transparency and embedded images. The {\em standalone} terminal -option allows you to create a *.tex document that can be processed by itself -without being embedded in a wrapping document. - -\section{Example of using the epslatex terminal driver} -\label{epslatex} - -The epslatex terminal driver allows you to mix the best features of \TeX\ -and PostScript. Text elements are typeset by \TeX\, while the graphic -elements are created and positioned in parallel by gnuplot's PostScript -driver. The plot can use either color or grayscale. -The driver produces two different files, one for the eps part of the figure -and one for the \LaTeX{} part. The name of the \LaTeX{} file is taken from the -`set output` command. The name of the eps file is derived by replacing -the file extension (normally ``.tex'') with ``.eps'' instead. - -With the epslatex terminal you cannot use ``\verb+\\+'' in a plain -string to denote newline. You can either put each line in a separate -label and specify vertical spacing -manually, or put the entire label in a \verb+\parbox+. -For example, the labels in Figure~\ref{epslatex_test} were -generated with the following commands: -\begin{verbatim} - x=.10; y=.15; dy=.05 - set label "left torus:" at screen x,y; y=y-dy - set label '$x=\cos u+\frac{1}{2}\cos u \cos v$' at screen x,y; y=y-dy - set label '$y=\sin u+\frac{1}{2}\sin u \cos v$' at screen x,y; y=y-dy - set label "$z=\\frac{1}{2}\\sin v$" at screen x,y - x=.65; y=.08 - set label '\parbox{2.5in}{right torus:\\$x=1+\cos u+\fr\ - ac{1}{2}\cos u \cos v$\\$y=\frac{1}{2}\sin v$\\\ - $z=\sin u + \frac{1}{2}\sin u \cos v$}' at screen x,y left -\end{verbatim} -\boxfigure{htbp}{\fullboxwidth}{ - \begin{center} - \input{eg7} - \end{center} - \caption{Interlocking tori demo, drawn using the epslatex driver.} - \label{epslatex_test} -} - -\begin{figure}[htbp] - \begin{center} - \input{test} - \end{center} - \caption{Line and point types for the basic latex terminal.
