I modified plotting panel and add all together we can choose one by one
Down tracks have three plotting Total_Energies,,,Kinetic_Energies,,,,Potential_Energies
We can choose what plotting.... i modified interface too and add three bars
For x,vx,vy,,, of course in plotting we have time VS "Energy (top part of rod in blue, bottom in red, total in black)
Time VS "Energy  (top in blue, bottom in red) etc  :)  ;D

Set x-axis to autoscale in plottingpanel!

Do you mean Prof add slide for zoom in plotting panel ?

In the plotting panel for kinetic energy and potential energy:
You set the minX to 0, I would suggest you remove that 0 (let the property field become empty)

Because you set it to 0 : the 0 will always be shown.
The x-axis will show the same range if you remove 0 in the property field.

OK prof but i delete now 0 from plotting kinetic and Potential but
Is the same show 0 ??

Yes prof i watch different after delete 0 from plotting panel Kinetic,,,Potential
You the best Prof  :)
