Please run the test on to_rgba_array()
directly, not on PathCollection
. While you've experienced the problem in PatchCollection
, the actual fault and behavior change is in that function. It's better to keep the scope of unit tests very focussed.

Sure, thanks. I've rewritten the unit test to test specifically the changed code in to_rgba_array
. Please let me know if there are any problems.
Plus, I am seeing building check failures due to subprocess timeouts which does not seem to be related to my code change. How should I fix this?
Something went wrong with the most recent commit it contains the plot_date deprecation, which is already on main. I suggest you squash and rebase on main. |

Sorry, I think it's because I synced fork by mistake. I made a new commit and the code changes are correct now. Also squashed the commits as suggested. |
CI failure is unrelated. I'm milestoning as 3.9 because I'd like to see this in there and the fix is quick and easy to review. |

pin pytest Deprecate plot_date Correctly set temporary pdf/pgf backends Calling `FigureCanvasPdf(figure)` will call `figure.set_canvas(self)`, meaning the `cbook._setattr_cm` context manager that wraps this change will see the _new_ canvas, and the old canvas isn't restored. Instead, just pass the `backend` parameter, as `savefig` already knows how to correctly save and restore the canvas if it needs to change backends.

PR summary
This change suggests a fix and hopefully closes #27839 by making sure that 'none' colors in a list won't be affected by custom alpha param.
Before the fix, this code:
will change rgba array of color list ['blue', 'none'] from:
to
After the fix, any 'none' color in a list of colors will be kept colorless.
A test is added to make sure the function works as expected.
