Easy way to display source localization results from label_time_course

Dear MNE community,

I am working on a project with low-density source localization, from which I would like to show the results on a parcellated cortex instead of per source point. Is there an easy way to show these results, extracted via mne.extract_label_time_course(…)?

I know that it can be done by setting all the source points in a certain area to the value in the label and thus reconstructing the full matrix, however, I was trying to find a more straightforward solution.

Thanks for your help!

Kind regards,
Steven
