Overview
This page documents a Python program designed to graph the first few seconds of power applied to the motors and robot speed. It is used to help calibrate PID parameters. I didn't know how to configure rqt_plot to display snapshots.
Plot termination Criteria
There are two termination criteria for termination 1) cnt-c and 2) time. After one of the criteria is met, the graph is drawn.
