PR Summary

This fixes both bugs identified in #19787

Still needs test and the tactic should be expanded to the other *Collections before we merge.

Looks like a real doc-build failure.... :-(

I was thinking about the fix @QuLogic put in for #18916 and was wondering if that was going to come back in other ways and it did!

No, I jumped to conclusion, but it is an easy fix. Running a full docs build locally before pushing.

I think you're running into the same issue as #18932 did, namely that legend copies the class, and so creates a 3D collection for its legend handle, without doing any of the 3D work.

I think this is slightly different, the problem is it is actually creating a the 3D class, rather than the slightly-upsetting

matplotlib/lib/mpl_toolkits/mplot3d/art3d.py

Lines 705 to 728 in bba76b8

def patch_collection_2d_to_3d(col, zs=0, zdir='z', depthshade=True):
"""
Convert a :class:`~matplotlib.collections.PatchCollection` into a
:class:`Patch3DCollection` object
(or a :class:`~matplotlib.collections.PathCollection` into a
:class:`Path3DCollection` object).
Parameters
----------
za
The location or locations to place the patches in the collection along
the *zdir* axis. Default: 0.
zdir
The axis in which to place the patches. Default: "z".
depthshade
Whether to shade the patches to give a sense of depth. Default: *True*.
"""
if isinstance(col, PathCollection):
col.__class__ = Path3DCollection
elif isinstance(col, PatchCollection):
col.__class__ = Patch3DCollection
col._depthshade = depthshade
col.set_3d_properties(zs, zdir)
so in the case of scatter we were creating it via the 3d props call, but in the scatter case we were running the __init__ which bounced to the super class which tries to set the linewidth before setup the 3D stuff.

Going to make an executive decision and say that @QuLogic can merge this on one review so we can get 3.4.1 out.

FIX: size and color rendering for Path3DCollection
f888285 
This fixes matplotlib#19787

This modifies the way we manage internal depth sorting of elements in the 3D
collections.  We need to both preserve the original order (so we can keep the
position, size, colour, ... in sync), but present each of them to the 2D
rendering code in depth order (back to front).  In some cases we can handle
this by sorting the values in the getter methods and in others we have to keep
a cache of both the sorted (the names used by the 2D code) and
unsorted (post-fixed with 3d) data.

It does not appear that Line3DCollection does any of the z-sorting that the
other collections do.  While definitely a limitation and produces MC Escher
effects, this is out of scope of the current work.

The z-sorting on Poly3DCollection is significantly more sophisticated than the
sorting on Path3DCollection and Patch3DCollection so it is handled
differently.
