Answer these questions (or I will ignore your issue)

1. Describe your platform / Operative System and the version of PlotJuggler you are using.

•   linux 20.04, ros noetic, plotjuggler 3.6.0
  

3. Compile and try the latest version in the main branch and check if the problem persists.
4. Check if the problem can be reproduced using the dummy data created by the command line argument "-t" or one of the files in the folder "datasamples".
5. If it can't be reproduced with the dummy data, please share the CSV file or the rosbag that can be used to reproduce the problem.
