Segmentation fault when running script multiple times.

1-Bart-1 commented 2 months ago

When running a script with this code twice from the julia command line, and closing the plotting window in between running the script the first time and the second time, I get the following error.

using ControlPlots
plot2d([[1,0,0], [2,0,0]], 10)

The version of ControlPlots I am using: ControlPlots v0.1.3

But the older version of ControlPlots (v0.0.12) had the same result.

This is interesting. I added the example mwe04.jl to reproduce the issue.

It must be related to the fact that I use a closure to keep the last points and lines stored, and when calling this function a second time only the positions get updated. And if you close the window the point and line objects do not continue to exist any more.

But why does this problem not appear if I run for example Tethers_07.jl from the Tethers.jl repo?

ufechner7 commented 2 months ago

OK, I see the reason: If you start a new 2D video sequence you must start it with t=0. Only then the line and dot and text objects are re-created. I would say this is OK, it just must be documented.

Add an example and some documentation to README.md
