Hey all,

I wonder if it is possible to plot this trajectory_msgs/Jointrajectory/points/velocities in rqt_plot?

image description

I want to show the joint velocities[5], in this case -0.86621.

Thank you in advance.

rqt_plot [YOUR_TOPIC]/points/velocities[5]

should work (obviously, adjust the topic name).

I couldn't get this to work with rqt_plot and there is no debug output. However I found a nice little plugin for rqt that I ported to PyQt5 so that it can be used in kinetic. You can find it here:

Just add it to your catkin workspace, compile, re-source and load it in rqt
