如何使用matplotlib绘制特定日期和时间的csv数据？

import pandas as pd
import matplotlib.pyplot as plt
from datetime import datetime

data = pd.read_csv('data.csv')
data['datetime'] = pd.to_datetime(data['datetime'])

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

start_date = datetime(2022, 1, 1)
end_date = datetime(2022, 12, 31)
filtered_data = data.loc[start_date:end_date]

plt.plot(filtered_data.index, filtered_data['value'])
plt.xlabel('Date')
plt.ylabel('Value')
plt.title('CSV Data')
plt.show()
