While going over the use of rqt_plot in this ROS 1 tutorial (https://wiki.ros.org/ROS/Tutorials/UnderstandingTopics#Using_rqt_plot) in preparation for porting it to ROS 2, we noticed some usability issues:

  • It is not possible to adjust the width of the rolling window, which makes it hard to see patterns in the waveform for this tutorial.
