Various tricks to make better plots in Matplotlib

right align legends

vp = leg._legend_box._children[-1]._children[0]
#for c in vp._children:
#    c._children.reverse()
vp.align="right" 

continuous color for line plot

cm = plt.get_cmap('hsv')
NUM_COLORS = 10
colorList = [cm(i/(1.*NUM_COLORS)) for i in range(NUM_COLORS)] # plt.plot(,color =)

Colormap from a list of colors

from matplotlib import colors
cmap=colors.LinearSegmentedColormap.from_list("mycolor",['white', 'red','green','black']) 

Figure label for subplots

labelbox =   dict(boxstyle="circle,pad=0.15", fc="cyan", ec="b",lw=0.5) 
plt.annotate("a",xy = (0,1),   bbox=labelbox )

Latex

plt.rc('text', usetex=True)
plt.rc('text.latex', preamble=r'\usepackage{amsmath}')
plt.rcParams["font.family"] = "serif"
plt.rcParams["mathtext.fontset"] = "dejavuserif"

Add a single colorbar for many subplots

im = pl.scatter or plt.imshow
fig = plt.gcf()
plt.subplots_adjust(right=0.8)
cbar_ax = fig.add_axes([0.85, 0.15, 0.05, 0.7])
plt.colorbar(im, cax=cbar_ax)

h5stream

Header only library for HDF5 input/output

Example

  // Create File
  h5stream file("sample.h5", "tr");

  // Create a vector
  std::vector<double> matrix { 1, 2, 3282, 932 };
  // Write to the file
  file.write<double>(matrix, "matrix"); // Call write_vector

  //Read data from the file
  auto xx = file.read<double>("matrix");
