Pandas version checks

  • I have checked that this issue has not already been reported.

  • I have confirmed this bug exists on the latest version of pandas.

  • I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

This is a similar issue to #36918 that has been fixed for df.boxplot. But the issue remains for df.plot.box:

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

rng = np.random.default_rng(0)
df1 = pd.DataFrame(
    rng.integers(0, 100, size=(100, 4)), columns=list('ABCD')
)
df2 = pd.DataFrame(
    rng.integers(0, 100, size=(100, 4)), columns=list('ABCD')
)

f, axs = plt.subplots(1, 2, figsize=(10, 7), sharey=True)
df1.plot.box(ax=axs[0], showfliers=False, vert=False)
df2.plot.box(ax=axs[1], showfliers=False, vert=False)

Issue Description

The current code raise an error:

ValueError: The number of FixedLocator locations (8), usually from a call to set_ticks, does not match the number of ticklabels (4).

Expected Behavior

No errors
