I want to plot 2 signals: desired velocity and current velocity. Both come from a Twist, and I want to plot /linear/x. I try with rqt_plot and it can successfully plot the desired velocity, but not the current velocity.

Please have a look here:

However I can see the topic is being correctly published with rostopic echo:

$ rostopic echo /current_velocity/twist/linear/x

What's the problem? Thanks!

The problem was that /current_velocity did NOT have a stamp in the header. After adding it it works perfectly!
