Working on a robotics project, I needed to determine whether the gyroscope inside my laptop, which is represented a joystick under linux, would be adequate for steering. To that end, I wrote a program to plot joystick value against time.
To run this program, you'll need python 2.7x and the corresponding versions of pygame and matplotlib. Under Windows, the python (x, y) package compilation is the easiest way to get started.
Run the file using python. It will tell you how many joysticks are plugged in. Enter the number joystick you want to plot, starting from 0. A pygame window will pop up. Once you have gathered enough data, close the pygame window. Your graphs will appear.
