levelsplot() funcction with StickSpectrum

[katarkon]

When levelsplot() used with Opt.StickSpectrum=true, the follow errors are throwed when mouse is moved over figure window:

Invalid or deleted object.
Error in levelsplot
Error while evaluating Figure WindowButtonMotionFcn
No lines are highlited, of course.
It seems to be a bug.

This is indeed a bug, thanks for reporting!

It seems that is more general problem. The error occures after the changing of spin system regardless drawing of the stick spectrum.
Only reboot of MATLAB solves the problem. Neither clearing of the figure nor its closing have no effect.

I hope it will be useful.
My system is Win10, MATLAB 2022a, EasySpin 6.0.6

Here the script:
clear, clf

Sys.S = 1/2;
Sys.Nucs='55Mn';
Sys.g=2.001;
Sys.A=mt2mhz(200)/10;

mwFreq=9.6;
Par.PlotThreshold=1e-3;
%Par.SlopeColor = true;
%Par.StickSpectrum = true;

B = [280 400]; % mT
levelsplot(Sys,'x',B,mwFreq,Par);

Just replace Sys.Nucs='55Mn' to Sys.Nucs='63Cu' and back.

Thanks for reporting! Indeed, this seems to be a bug that needs a bit more work to fix. Please post an issue here: https://github.com/StollLab/EasySpin/issues

The bug does not seem to be reproducible. I cannot find unambiguous conditions when it occurs.
Also there is a minor bug with linewidths of transitions at levelsplot diagram. They are initially thicker than ones after mouse hilighting.
