如何在Matplotlib和Pandas中绘制带日期时间的阴影区域？

import matplotlib.pyplot as plt
import pandas as pd

data = pd.DataFrame({'date': pd.date_range(start='2022-01-01', end='2022-01-10'),
                     'value': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]})

data.set_index('date', inplace=True)

plt.plot(data.index, data['value'])

start_date = '2022-01-03'
end_date = '2022-01-07'

start_index = data.index.get_loc(start_date)
end_index = data.index.get_loc(end_date)

plt.axvspan(data.index[start_index], data.index[end_index], facecolor='gray', alpha=0.3)

plt.legend(['Value'])
plt.title('Plot with Shaded Area')
plt.xlabel('Date')
plt.ylabel('Value')

plt.show()
