outline attribute of colorbar not documented #19946
Description
Was trying to change the color of the outline of my colorbar:
and wasn't clear in the docs how to do it, but found on stackoverflow that there's an outline attribute that is the collection of spines:
self.outline = ax.spines['outline'] = _ColorbarSpine(ax)around the colorbar (and is not the same spines as the axes containing the colorbar since I tried that and it didn't work.)

Note #18900 will likely change this behaviour to be exactly the same as any other axes...

With the new
Axes.spinesshortcut, you can useax.spines[:].set_color('red')on anyAxeswithout worrying about the names.anushkrishnav commentedon Apr 20, 2021
I would like to work on this issue

AFAICS there is no clear action:
ax.spines['outline']for colorbars if that will change to standard behavior in Enh better colorbar axes #18900.ax.spines[:]works on any axis. It's documented onSpinesand it doesn't make sense to add documentation on a general feature specifically to colorbars.@story645 do you see any specific documentation that we should add that would have helped you? Otherwise I propose to close this.
@anushkrishnav Sorry that the action status is not clear/up-to-date.

Haven't closed it because I think it could be useful as a backport only doc (since ax.spines doesn't work on earlier versions) but I don't know quite how far back it'd be backported

I don't think we rebuild old docs...

ax.spines[:]is new in 3.4. https://matplotlib.org/stable/api/spines_api.html?highlight=spines#matplotlib.spines.SpinesWe don't update docs for previous releases. So I'm closing this as nothing to do.
@story645 Maybe you want to twitter about this some day? This is not as glorious as
subplot_mosaic, but a nice API to share.
