Simplify axes and axis clearing, sharing, and aspect ratio control #8752
Conversation
- Most of the unnecessary calls to Axis.cla() have been removed. - Axis sharing works across figures. - The "box-forced" adjustable is no longer needed. - Sharing both axes requires the use of "box", not "datalim". - A new "share" kwarg triggers synchronized setting of aspect ratio and adjustable in Axes within shared axis groups. - Added a test for axis sharing with aspect ratio setting. - Fixed and updated skew_rects test.

Odd failure ("image file not readable") on the doc build: |

Looks like some PEP8 errors too https://travis-ci.org/matplotlib/matplotlib/jobs/242143280#L2558 |

Some of these changes are similar to #8626, though perhaps with slightly different triggers. |

Axes, Axis, Spine, and Tick are all inexplicably intertwined. I've been trying to disconnect them (e.g., #8678), but there's always one last bug every time...

Seems like it should be in __init__.

Actually it is already in _get_label, so I don't think we need it in cla or init.

reset_ticks deletes all ticks; they'll get recreated with the updated parameters from the dictionary.

@QuLogic, thank you for the review. I have addressed the minor points. I'm sorry for the overlap with your work; I haven't been keeping up with existing PRs. |
This is required for consistency with the present grid() documentation and behavior, but the list of allowed properties should be trimmed.
|
This would close #2790; the test case described at the top of that issue works correctly. |
|
I do not think forcing shared axes to 'box' is right import matplotlib.pyplot as plt
fig, ax = plt.subplots()
ax2 = ax.twinx()
ax.set_aspect(5)gives
on this branch. |
This is to allow twinx and twiny to work as expected.
|
@tacaswell, yes, the twinx situation has to be handled differently. This arose recently in another issue as well. Twinx needs to ensure that the two axes have the same position, even if the position of one or the other is changed by any means. |
|
Pinging on the status of this PR or if there is any way I can help. I've assiduously avoided the aspect code in #9082 (layout manager) but it'll come up at some point. Knowing what the API is and what the current code is meant to do would be great... |
|
Parts of this have come in via other PRs. The part that hasn't--the reduction of unnecessary clearing--will require a fresh look. Closing. |
