如何在pandas中仅绘制营业时间和工作日

import pandas as pd
import matplotlib.pyplot as plt

# 创建示例DataFrame
data = {
    'Date': pd.date_range(start='1/1/2023', periods=10),
    'OpeningTime': [9, 9, 10, 10, 11, 11, 9, 9, 10, 10],
    'ClosingTime': [18, 18, 17, 17, 16, 16, 18, 18, 17, 17],
    'IsWeekend': [False, True, False, True, False, True, False, True, False, True]
}
df = pd.DataFrame(data)

# 筛选工作日数据
workdays = df[df['IsWeekend'] == False]

# 绘制营业时间
plt.figure(figsize=(10, 5))
plt.plot(workdays['Date'], workdays['OpeningTime'], label='Opening Time', marker='o')
plt.plot(workdays['Date'], workdays['ClosingTime'], label='Closing Time', marker='s')
plt.xlabel('Date')
plt.ylabel('Time')
plt.title('Business Hours on Workdays')
plt.legend()
plt.grid(True)
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()
