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

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

  • (optional) I have confirmed this bug exists on the master branch of pandas.

Code Sample

import pandas as pd
import numpy as np

pd.DataFrame(dict(
    a=[np.nan, np.nan],
    b=[1, 2],
    ts = [pd.Timestamp('2020-01-01'), pd.Timestamp('2020-02-02')]
)).set_index('ts').plot()

Problem description

The x-axis (time axis) start in before 2000 where it really should start at 2020-01-01

Looks like this has been fixed. I just tried it in pandas==2.2.3 and it looks good:
