bug: unexpected behavior of inset colorbar

[syrte]

Description

Unexpected behavior of inset colorbar with keywords tickloc and labelloc.

Steps to reproduce

The code below

import proplot as pplt
import numpy as np

fig, axes = pplt.subplots(None, 1, 2)
cm = axes[0].scatter(*np.random.rand(4, 10), vmin=0, vmax=1)

axes[0].colorbar(cm, loc='ll', length=10, width=0.8, label='abc', tickloc='top')
axes[1].colorbar(cm, loc='ll', length=10, width=0.8, label='abc', labelloc='top')

gives this

If I understand correctly,
left panel: we would expect the ticks shown at the top when tickloc='top' is set.
right panel: strange padding when placing the label on the top.

I tried to fix the padding in the right panel, it turns out not easy for me ...

Proplot version

Paste the results of import matplotlib; print(matplotlib.__version__); import proplot; print(proplot.version)here.

3.4.3
0.9.5.post284

Yeah... the inset colorbar implementation is unfortunately just very flimsy right now. I'm working on a fix in #311 that will automatically adjust the position of the colorbar axes and frame using its tight bounding box. Have already done the hard part (figured out how to auto-anchor an axes and adjust a background frame), just have to integrate with ax.colorbar().

Will try to merge #311 before the next release (.....sometime this month) because I'm uncomfortable publishing a new release with such fragile behavior. It was under-tested in previous versions.

Thank you Luke for the hard work! Look forward to the fix.

BTW, one more example about incorrect padding (too large) in the third panel below. From your description, I guess auto-anchor things would fix this behavior as well ;)

Also another strange behavior, note the location of label in the middle panel, it has been changed when plotting the right panel. If I use different cm objects, then it would be at the correct location as in the previous figure.

Code

import proplot as pplt
import numpy as np

fig, axes = pplt.subplots(None, 1, 3)
cm = axes[0].scatter(*np.random.rand(4, 10), vmin=0, vmax=1)

axes[0].colorbar(cm, loc='ll', length=10, width=0.8, label='abc', tickloc='top')
axes[1].colorbar(cm, loc='ll', length=10, width=0.8, label='abc', labelloc='top')
axes[2].colorbar(cm, loc='ll', length=10, width=0.8, label='abc', labelsize='x-small', ticklabelsize='x-small')
