如何在Python Matplotlib中将标注添加到雷达海图点

import numpy as np
import matplotlib.pyplot as plt
from math import pi

# 数据准备
labels = ['A', 'B', 'C', 'D', 'E']
stats = [4, 3, 2, 5, 4]

# 计算角度
angles = np.linspace(0, 2 * pi, len(labels), endpoint=False).tolist()
stats += stats[:1]  # 闭合图形
angles += angles[:1]

# 绘制雷达图
fig, ax = plt.subplots(figsize=(6, 6), subplot_kw=dict(polar=True))
ax.fill(angles, stats, color='red', alpha=0.25)
ax.plot(angles, stats, color='red', linewidth=2)

# 添加标签
ax.set_theta_offset(pi / 2)  # 设置起始角度
ax.set_theta_direction(-1)   # 设置绘图方向
plt.xticks(angles[:-1], labels)

# 添加标注到特定点
for angle, stat in zip(angles, stats):
    ax.text(angle, stat + 0.2, str(stat), ha='center', va='center')

plt.show()
