在matplotlib中合并条形图和线形图，而不移动条形图

import numpy as np
import matplotlib.pyplot as plt

categories = ['A', 'B', 'C', 'D', 'E']
bar_data = [5, 8, 3, 9, 4]  # 条形图数据
line_data = [0.5, 0.8, 0.3, 0.9, 0.4]  # 线形图数据

fig, ax1 = plt.subplots()

# 创建辅助坐标轴
ax2 = ax1.twinx()

ax1.bar(categories, bar_data, color='blue')
ax2.plot(categories, line_data, color='red')

ax1.set_ylabel('Bar Data')
ax2.set_ylabel('Line Data')
plt.title('Combined Bar and Line Chart')

plt.show()
