Can it be the size of the png being 2 big?

var plt = new ScottPlot.Plot(2000, 1000);

I would say its most likely the data set that is causing the issue.

Sounds good! I’ll close this issue for now, but if you find that ScottPlot is the underlying cause feel free to open the issue again (perhaps with sample data that causes crashes) and I can take a closer look.

I’m glad you enjoy using ScottPlot! Good luck with your coding 👍

it occurrs in a some tests! doesnt seem to be related with agent since others tests run fine in that agent! i would say its most likely the data set that is causing the issue. i will do what u suggested and let u know if it works. thanks
