This will allow tweaking the displayed signature of figure(), e.g.
hiding facecolor and edgecolor (likely rarely used) into kwargs
while making e.g. layout more prominent.

(I deemed that passing figsize or dpi positionally, although probably not a good idea, could possibly make sense, but that's almost certainly not the case for facecolor and edgecolor...)

PR Summary

PR Checklist

Tests and Styling

  • Has pytest style unit tests (and pytest passes).
  • Is Flake 8 compliant (install flake8-docstrings and run flake8 --docstring-convention=all).

Documentation

  • New features are documented, with examples if plot related.
  • New features have an entry in doc/users/next_whats_new/ (follow instructions in README.rst there).
  • API changes documented in doc/api/next_api_changes/ (follow instructions in README.rst there).
  • Documentation is sphinx and numpydoc compliant (the docs should build without error).

This will allow tweaking the displayed signature of figure(), e.g.
hiding `facecolor` and `edgecolor` (likely rarely used) into `kwargs`
while making e.g. `layout` more prominent.

At the risk of annoying some users. But

  • hopefully not many people are affected.
  • in their own interest, they should not pass these parameters positionally.
  • it serves a concrete purpose within matplotlib (to improve the signature).
  • it's a regular depreaction, so those who are affected have time to transition.

If this was new API, dpi would be kw-only, but I agree that we should be defensive to not affect more people than necessary.
