如何使pyplot图表中的y轴显示两个相同值的测量值(计数和百分比)？

import matplotlib.pyplot as plt
import numpy as np

categories = ['Category A', 'Category B', 'Category C']
counts = [10, 20, 30]
percentages = [25, 50, 75]

fig, ax1 = plt.subplots()

# 绘制计数值的柱状图
ax1.bar(categories, counts, color='blue')
ax1.set_ylabel('Count')

# 创建第二个y轴
ax2 = ax1.twinx()

# 绘制百分比值的折线图
ax2.plot(categories, percentages, color='red', marker='o')
ax2.set_ylabel('Percentage')

# 设置图表标题和x轴标签
plt.title('Count and Percentage')
plt.xlabel('Categories')

# 显示图表
plt.show()
