Charts data fed through serial port(USB) of android device in host mode via OTG or usb host port

Issue 1: AC signals have zero between every data point

Issue 2: Pause and toggle buttons dont work yet

Issue 3: How to get accuracy from serial port wihout reducing speed

Issue 4: App crashes when the back button is presses while in a charting activity_>debatable, only observed on toshiba tablet

Issue 5: Connect/Disconnect button on splash screen does not work_>_works after arduino is plugged out and plugged back in

Issue 6: For smartphone with smaller batteries, may not power arduino properly, will it work with alternate power source?

Issue 7: Capture data in buffer and only display one time interval

Issue 8: Label x values in units of time

Issue 9: Provide buttons to choose which channel the graph may take data from

Issue 10: Change ICON

Issue 11: Allow opening and closing of serial port via button, instead of automatic action, tied to issue 5

Issue 12: Chart is lost of one leaves the activity

Issue 13: Graph and app by extension gets slow when charting for a while, especially if view port covers entire graph

Issue 14: Graphs charting looks like crap

Issue 15: Create a settings activity, allow user to change serial protocols like baud rate, parity e.t.c.

Issue 16: Allow users to change colour of graph or lines for charting

Issue 17: App looks too basic, improve User Interface, add animations

Issue 18: Saved graph images overwrite previously saved graph images of the same type

Issue 19: AutoSet feature does not work 100% of the time

Issue 20: Lots of data points are dropped during charting, reduces the apprent smaple rate on graph

Issue 21: App slows down, crashes even, when the number of points is increased, UI thread doing too much work

Issue 22: Passing data to Splash is unecessary, do intial calculations in service and pass data to charting activies directly

Issue 23: Data on chart is not even, comes in short bursts which reduces chart accuracy
