Matplotlib绘制极坐标雷达图

Matplotlib编程实现

import numpy as np
import matplotlib.pyplot as plt

num = 20
theta = np.linspace(0.0, 2 * np.pi, num, endpoint=False)
radii = 10 * np.random.rand(num)
width = np.pi / 4 * np.random.rand(num)

ax = plt.subplot(111, projection='polar')
bars = ax.bar(theta, radii, width=width, bottom=0.0)

for r, bar in zip(radii, bars):
    bar.set_facecolor(plt.cm.viridis(r / 10.))
    bar.set_alpha(0.5)

plt.show()
