如何在python中的一个雷达图上映射多个热图图？

import numpy as np
import matplotlib.pyplot as plt

# 生成雷达图的数据
categories = ['Category 1', 'Category 2', 'Category 3', 'Category 4', 'Category 5']
values = [0.4, 0.6, 0.8, 0.2, 0.9]

# 生成热图的数据
heatmap_data = np.random.rand(len(categories), len(categories))

# 绘制雷达图
fig = plt.figure(figsize=(6, 6))
ax = fig.add_subplot(111, polar=True)
theta = np.linspace(0, 2 * np.pi, len(categories), endpoint=False).tolist()
theta += theta[:1]  # 闭合图形
values += values[:1]  # 闭合图形
ax.plot(theta, values, 'o-', linewidth=2)
ax.fill(theta, values, alpha=0.25)

# 绘制热图
fig, ax = plt.subplots(figsize=(6, 6))
heatmap = ax.imshow(heatmap_data, cmap='hot', interpolation='nearest')
ax.set_xticks(np.arange(len(categories)))
ax.set_yticks(np.arange(len(categories)))
ax.set_xticklabels(categories)
ax.set_yticklabels(categories)
plt.colorbar(heatmap)

# 显示图形
plt.show()
