I recently learned pandas and data visualization and made a practice program

         #coding:utf-8
            import tushare as ts
            import pandas as pd
            import matplotlib.pyplot as plt
            import matplotlib.dates as mdate
        
    ......
            
            fig1 = plt.figure(figsize=(15,5))
            ax1.xaxis.set_major_formatter(mdate.DateFormatter('%H:%M'))#設(shè)置時(shí)間標(biāo)簽顯示格式
            plt.xticks(pd.date_range(start='09:00',end='09:10',freq='60S'),rotation=90)
            plt.title('percent')
            plt.plot(real_data_ave,'.-')
            plt.show()

The problem is that when I do this, I can’t see the time on the X-axis. How to solve it?
