About
This is a simple utility to plot 2D data. The motivation for this is to have a "live" plotting program that can take data from an embedded system connected over USB.
Status
Source plot.py. This opens a black window with some debug text and a 2d grid.
N: increase number of grid linesShift+N: decrease number of grid lines
Set window size in plot.py using OS_WIN_SCALE.
Dependencies
Install pygame to a virtual environment. Activate the virtual environment for development and for usage.
Design
Use pygame.
Keep the pygame boilerplate in mjg_pygame.py in class PGG (PyGame Globals). Inherit PGG in the main application plot.py to make child class GUI with application-specific stuff.
The plot.py script in this repo is meant to be an example application. I'm trying to keep the code in plot.py minimal and put most of the code into unit tested modules.
Modules start with mjg_. The main script does not have the mjg_ prefix.
Unit tests
Unit test with both unittest.Testcase and with doctest. Use unittest for traditional assert-style unit tests. Use doctest when traditional assert-style unit tests are too much work. Use doctest to keep the docstrings in sync with the code.
I don't unit test mjg_pygame.py because I don't know how and it's just glue anyway. This module is not going anywhere.
The other modules are unit-tested but they are subject to change a lot as I discover how this project wants to come together. For now, the other modules are mjg_calc.py and mjg_plot.py.
