fix y axis on 3d plot - #21424

Conversation
This commit corrects the axis which the 3D y axis inherits from. The y-axis on 3D plots initially inherited from the x axis object, rather than a y axis object. This resulted in a bug where the x axis (instead of the y) was inverted for 3D plots when was called. After inheritance correction, correct behavior was achieved with inversion, but the tick marks were incorrectly placed. The default location for tick marks on the y-axis is now set to be right, rather than left. Resolves matplotlib#21369

Does this work okay if you rotate the axes so that the y axis is on the left side? There may be some automated alignment picker that assumes the labels were on the 'bottom of the x axis'. I think the other test failures are in the wrong grid lines. I'll mark this Draft for now. |

Good point. I will check for that. |

I've tried rotation with both the feature and main versions of this code reported in the issue with the following results (attached). The first figure is from this feature branch, the second is from main branch.
There is no resulting error, and with a rotation of 200 degrees, each appears okay. Is there a recommended more systematic way to test this? There does seem to be something that needs to be fixed for this branch when a Y label is present (y label and tick labels overlap), so this is a to-do:

OK, that's good. If you want to test directly at some direction, you can use |

Hi @QuLogic - thanks. I did use It seems like some failures may have to do with reference figures, and I'm not sure how I would approach this. |
|
Image diffs for failing mplot3d tests look mostly like this. Would the proper course of action be to change the reference images?
|

That one is likely okay, but the ones with extra tick lines (e.g., |

I'm going to close this because we resolved the issue in a different way. Thank you for your work @janash and I hope we hear from you again! |
