thanks for the PR, @VirosaLi

just curious where is this warning getting caught or is the warning raised on a newer matplotlib version, do we have any tests right now to catch the warning?

pandas/tests/plotting/test_frame.py: 10 warnings
pandas/tests/plotting/test_series.py: 5 warnings

ax.set_xticklabels(xticklabels)

@VirosaLi so the warning is now gone? I don't think we actually need a test for this, but if you can put an assert_produces_warning(None) around something and have it pass would be great.

lgtm

if you could get the CI green (failure doesn't seem relevant to the PR though, maybe try to rebase one more time)

[charlesdong1991]

the first one will be resolved once #36085 gets merged.

thanks @VirosaLi
