填充极坐标中的两条线

Question

我正在尝试填充两端未关闭的两条线之间的空间.我不能得到plt.fill_between与plt.polar,任何想法？这是我用来绘制线条的代码:

import matplotlib.pyplot as plt
import numpy as np 

inner_offset = 0.05
r = np.arange(inner_offset,1. + inner_offset,1./720.)
theta = np.arange(0.,2.,1./360.)*np.pi 

plt.polar(theta/2.,r) #first part of spiral
plt.polar((theta/2.)+(np.pi/3.),r)

plt.show()

Answer 1

由于您的radius("y")是相同的,您可以使用plt.fill_betweenx():

import matplotlib.pyplot as plt
import numpy as np

plt.figure()
inner_offset = 0.05
r = np.arange(inner_offset,1. + inner_offset,1./720.)
theta = np.arange(0.,2.,1./360.)*np.pi

c1 = plt.polar(theta/2.,r, color='b')[0]
x1 = c1.get_xdata()
y1 = c1.get_ydata()
c2 = plt.polar((theta/2.)+(np.pi/3.),r, color='y')[0]
x2 = c2.get_xdata()
y2 = c2.get_ydata()

plt.fill_betweenx(y1, x1, x2, color='g')
plt.show()
