sure, done.

@meeseeksdev backport to v3.7.x

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

git checkout v3.7.xgit pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 087ca0c615f697dc857277b0fb87657c13ee0eed

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #24843: Show that fill_between and span_where provide similar functionalities.'

4. Push to a named branch:

git push YOURFORK v3.7.x:auto-backport-of-pr-24843-on-v3.7.x

5. Create a PR against branch v3.7.x, I would have named this PR:

"Backport PR#24843 on branch v3.7.x (Show that fill_between and span_where provide similar functionalities.)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove theStill Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free tosuggest an improvement.

OK, will do it as part of the merge myself.

Actually, I misunderstood the conflict; this conflicts because it was deprecated in 3.7; there's no need to backport this PR.
