如何在海运中设置datetime xlim

import matplotlib.pyplot as plt
import datetime

# 海运数据
shipping_data = [
    {'date': datetime.datetime(2022, 1, 1), 'value': 10},
    {'date': datetime.datetime(2022, 1, 2), 'value': 15},
    {'date': datetime.datetime(2022, 1, 3), 'value': 20},
    {'date': datetime.datetime(2022, 1, 4), 'value': 25},
    {'date': datetime.datetime(2022, 1, 5), 'value': 30},
    {'date': datetime.datetime(2022, 1, 6), 'value': 35},
]

# 提取日期和值
dates = [data['date'] for data in shipping_data]
values = [data['value'] for data in shipping_data]

# 绘制折线图
plt.plot(dates, values)

# 设置时间范围
start_date = datetime.datetime(2022, 1, 2)
end_date = datetime.datetime(2022, 1, 5)
plt.xlim(start_date, end_date)

# 显示图形
plt.show()
