Does geographic axes support axis sharing?

[gepcel]

Most examples in the doc uses share=0 or share=False. Does and can geographic axes support share/sharex/sharey arg?

fig,axs=pplt.subplots(ncols=2,proj='cyl',refwidth='6cm',share='all')
axs.format(lonlim=(100, 105), latlim=(30, 35),labels=True)
axs[1].format(lonlines=2,latlines=1)

Yes we do! But only for rectilinear axes for geo (merc, cyl etc)

[cvanelteren]

iirc I added that option to prevent the log filling the output

[cvanelteren]

How sharing works it that we by default scan what could be shared, i.e.

[1, 2],
[3, 4]

can be shared but this

[1, 2]
[1, 3] makes no sense to share y.

So the mechanisms is actually rather nice at is does "works" for sharing complicated structures where it makes sense -- at least I think it is nice but I also wrote it 😆. This story holds generic and also stops sharing if the subplot types differ so

[1, 2, 3] would share 2, 3 if 2, 3 are geo (and rectilinear) and 1 is not

[gepcel]

So what happened to the following example?

Example 1

fig,axs=pplt.subplots(ncols=2,proj='cyl',refwidth='6cm',share='all')
axs.format(lonlim=(100, 105), latlim=(30, 35),labels=True)
axs[1].format(lonlines=2,latlines=1)

[cvanelteren]

y label is turned of as it is sharing it with the left one. For the right one you formatted it differently; would need to check why this is not getting carried over.

[cvanelteren]

So I had to look this up as I vaguely recalled that I changed this behavior. The rationale is that even for shared states that axis specific indexing presumes that the user wants to modify that axis even within a shared state. So what you are seeing is that the plot is putting the grid in a different split while trying to comply with the same range.

The relevant commit is: #8f66423a

[gepcel]

But the behavior is not consistent for non geo axes

fig,axs=pplt.subplots(ncols=2,refwidth='6cm',share='all')
axs.format(xlim=(100, 105), ylim=(30, 35),labels=True)
axs[1].format(xticks=2, yticks=1)

[cvanelteren]

This might be a cartopy idiosyncrasy let met investigate at bit

[cvanelteren]

Ah nvm yeah you are right. That needs fixing.

Edit: I need to confirm first what my earlier comment referred to as I do think that was the intention from that past commit.

[cvanelteren]

Ok that issue is fixed on main @gepcel!

Closed by #801

[cvanelteren]

I more stuff comes up let me know as the sharing things are rather complex for me to sometimes track and it is probably not complete yet.

[gepcel]

Ah, I thought things are done. I didn't see what you changed, but a simple test shows it solved. If there's other thing you'd like to do, you can reopen this issue as a reminder.
