在matplotlib中显示两个颜色条

import numpy as np
import matplotlib.pyplot as plt

# 生成示例数据
x = np.linspace(0, 10, 100)
y = np.linspace(0, 10, 100)
X, Y = np.meshgrid(x, y)
Z1 = np.sin(X) + np.cos(Y)
Z2 = np.cos(X) - np.sin(Y)

# 绘制图像
fig, ax = plt.subplots()

# 绘制第一个图像和颜色条
im1 = ax.imshow(Z1, cmap='coolwarm')
cbar1 = plt.colorbar(im1, ax=ax, extend='min')

# 绘制第二个图像和颜色条
im2 = ax.imshow(Z2, cmap='viridis', alpha=0.5)
cbar2 = plt.colorbar(im2, ax=ax, extend='max')

# 设置颜色条标签
cbar1.set_label('Z1')
cbar2.set_label('Z2')

# 显示图像
plt.show()
