Matlab2025b plotting sluggishne​ss/inconsi​stencies

Folks,

I am having great difficutiles using the Matlab 2025b "plot" command from a standard Matlab console or script to generate simple plots of 1d arrays like x versus y using the '-' line (not individual points). It worked fine in Matlab 2022b. The arrays have sizes of 300,000 x 1. The issues I am getting are in the form of hangs and the axes not automatically scaling to the correct boundaries to show the data. I am wondering if others are having such issues, and if there is a rendering setting I can change that might improve the behavior to more like 2022b. This is my first experience with 2025b and I'm very concerned.

Best regards,

Kris

I have not noticed any problem like this with R2025b on MacOS Intel.

Could you perhaps attach a .mat file with sample data that you are having trouble with?

I unfortunately cannot do this, Walter.

Does the same thing happen if you plot rand(1,300000) ? Does it happen if you plot rand(1,3000) ?

Walter, I don't have 2025b anymore. I also have limited time to test new ideas for what are sporadic errors that are not entirely repeatable. I hope you understand, and I always very much appreciate your's and other's help on here when you volunteer your ideas and time.

If you were to contact Mathworks Support, it is not entirely impossible that they might have already have a published bug report with solution for this situation. I don't think it is all that likely, but it is not impossible.

Short of that, there is no solution that does not involve a certain amount of experimentation.

I know. I lost interest in trying different renderers between when I first posted this and earlier today when I just had too many issues. Feel free to delete teh post.
