如何在Matplotlib中移动极轴图中的ytick标签

import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111, polar=True)

theta = np.linspace(0, 2*np.pi, 8, endpoint=False)
r = np.random.rand(8)

lines, labels = ax.set_thetagrids(theta * 180/np.pi, [])
ax.plot(theta, r)

ax.set_yticks([])  # 隐藏原始的ytick标签

# 创建新的ytick标签
ytick_labels = ['Label 1', 'Label 2', 'Label 3', 'Label 4', 'Label 5']
ytick_angles = np.linspace(0, 360, len(ytick_labels), endpoint=False)
ytick_angles = np.deg2rad(ytick_angles)

# 绘制新的ytick标签
for angle, label in zip(ytick_angles, ytick_labels):
    ax.text(angle, 1.1, label, transform=ax.transAxes, va='center', ha='center')

ax.set_ylim(0, 1)  # 设置极轴图的y轴范围
ax.spines['polar'].set_visible(False)  # 隐藏极轴图的边框
ax.grid(False)  # 隐藏极轴图的网格线

plt.show()
