如何在Python中将分钟时间设置为Matplotlib图的x轴？

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

fig, ax = plt.subplots()

import datetime

times = [datetime.datetime(2022, 1, 1, 0, 0),
         datetime.datetime(2022, 1, 1, 0, 15),
         datetime.datetime(2022, 1, 1, 0, 30),
         datetime.datetime(2022, 1, 1, 0, 45)]
values = [10, 20, 15, 25]

x = mdates.date2num(times)

ax.plot(x, values)

ax.xaxis.set_major_locator(mdates.MinuteLocator(interval=15))
ax.xaxis.set_major_formatter(mdates.DateFormatter('%H:%M'))

ax.set_xlabel('Time')
ax.set_ylabel('Value')
ax.set_title('Plot with Minute X-axis')

plt.show()
