与极坐标相关的图形绘制plt.polar()

import matplotlib.pyplot as plt
import numpy as np
import matplotlib as mpl

x = np.linspace(0, 1, 100)
y = 2*np.pi*x

x1 = 30*np.random.rand(100)
y1 = 2*np.pi*np.random.rand(100)
colors = np.random.rand(100)
size = 50*x1

ax = plt.subplot(121, polar=True)
ax.plot(x, y, color="r", linestyle="-", linewidth=2)

ax1 = plt.subplot(122, polar=True)
ax1.scatter(x1, y1, s=size, c=colors, cmap=mpl.cm.PuOr, marker="*")


plt.show()

2.

import numpy as np
import matplotlib.pyplot as plt

barSlices = 12

theta = np.linspace(0.0, 2*np.pi, barSlices,endpoint=False)#角度
r = 30*np.random.rand(barSlices)#值

plt.polar(theta,r,color="chartreuse",linewidth=5,marker="*",mfc="b",ms=6)
#mfc-------->星的颜色  ms-------->星的大小

plt.show()
