在使用datetime时，如何在x轴上显示时间？

import matplotlib.pyplot as plt
import matplotlib.dates as mdates
from datetime import datetime

dates = [datetime(2022, 1, 1), datetime(2022, 1, 2), datetime(2022, 1, 3), ...]

data = [10, 15, 20, ...]

fig, ax = plt.subplots()

formatted_dates = mdates.date2num(dates)

ax.xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d'))

ax.plot(formatted_dates, data)

plt.xticks(rotation=45)

plt.show()
