X Title: Warn on non-increasing/decreasing pcolor coords by greglucas · Pull Request #18398 · matplotlib/matplotlib

Description: PR Summary pcolor* will now automatically calculate bin edges for users if shading is 'auto' or 'nearest'. This can lead to surprising resulting edge calculations if the coordinate arrays are not sorted prior to calling the function. Addresses part of #18317. This would be good to get into v3.3.2 for at least warning users about this use case and then leave the other potential screen-space interpolations for v3.4. PR Checklist Has pytest style unit tests (and pytest passes). Is Flake 8 compliant (run flake8 on changed files to check). [N/A] New features are documented, with examples if plot related. [N/A] Documentation is sphinx and numpydoc compliant (the docs should build without error). Conforms to Matplotlib style conventions (install flake8-docstrings and pydocstyle<4 and run flake8 --docstring-convention=all).
