如何在x轴上创建和清空带有日期的散点图- Python，Pandas？

import pandas as pd
import matplotlib.pyplot as plt

data = {'date': ['2022-01-01', '2022-01-02', '2022-01-03'],
        'value': [10, 15, 20]}
df = pd.DataFrame(data)

df['date'] = pd.to_datetime(df['date'])

plt.scatter(df['date'], df['value'])
plt.xlabel('Date')
plt.ylabel('Value')
plt.title('Scatter Plot')
plt.show()

plt.clf()
