matplotlib: missing types

[mvolkmann]

Do I understand correctly that Pylance bundles type stub files for popular libraries like matplotlib?
I get type errors for some things and I wonder if they are just missing from the bundled stub files.
For example, it doesn't recognize that Axes objects have a clear method and this import gives an error:

import matplotlib.animation as animation

Can I add my own versions of these stub files in the typings subdirectory of my project to override them?
If so, what file names do they need to have?

[jakebailey]

Yes, it does, and the matplotlib stubs aren't fully complete yet (at least for anything but autocompletion, our original reason for putting them there).

You can override them by adding typings/matplotlib, and the folder structure in there, or install a package that overrides them. The bundled stubs are read last overall (typings, installed stubs, original code).

Oops! @jakebailey I guess you didn't want to close this yet. I reopened it.

[jakebailey]

Yes, I need to find some time to fix the matplotlib stubs.
