The plots in live editor don't show up unless I press the open in figure window option.

Hi.

I am working on a school project and everything was going fine yesterday, but this morning when I ran the live scripts the plots show up empty in the live editor. I can still see the plots, but I have to press the "open in figure window" option, which is irritating. Any suggestions?

Hi Dagur,

Could you help me with the live script that you are running so that I can reproduce the issue at my end?

I ran the code provided on MATLAB R2023a and encountered no issues. To better understand the case, could you share a screenshot that demonstrates the issue? Additionally, let me know if you have restarted MATLAB as a troubleshooting step.

Further, I recommend trying the workarounds mentioned in the link attached below as a intital step to resolve the issue

Works for me as well in R2021a, see the attached screenshot.

I get the Graphics timeout occured warning

As you can see the figure turns up empty

Could you please try launching MATLAB from the command line using the 'softwareopenglmesa' flag by executing the command

>> matlab -softwareopenglmesa

[Dagur]

This did not work but the "matlab -softwareopengl" flag did. The plots can now be seen in the matlab editor. Can you explain why this works

[Akshat]

'-softwareopengl' is a startup option that is used when invoking MATLAB from the command line. It is brought into use to manage the OpenGL libraries when MATLAB detects a graphics driver with known issues. Leveraging this option forces MATLAB to start with software OpenGL libraries.

As the issues is resolved, I would be summarising and moving the discussion to an answer for future reference.

Hi @Dagur,

I understand that you are facing issues with plots in the live editor. In reference to the code shared, the issue could not be reproduced on MATLAB R2023a and MATLAB R2021a. On subsequent discussions in the comments, it was found that, a Graphic Timeout Error warning was being thrown which was resolved through invoking MATLAB from the command line using the '-softwareopengl' flag which forces MATLAB to start with software OpenGL libraries.

>> matlab -softwareopengl

I hope this helps.
