如何在 Python 中画一个圆圈并用各种颜色给线段着色？

Question

我想绘制多个圆圈，一个在另一个圆圈内，将它们的边界分成 N 个相等的部分，并用特定颜色为每个圆圈的每个部分着色，如下图所示： circle （不幸的是，这里只显示了一个圆圈。我想以这种方式绘制多个圆圈，一个在另一个圆圈中。）

如何在 Python 中执行此操作？

Answer 1

您要找的词是Nested pie charts。您可以从 matplotlib.

尝试类似 this 的内容

示例来自here。

import matplotlib.pyplot as plt
 
# Data to plot
labels = ['Python', 'C++', 'Ruby', 'Java']
sizes = [504, 337, 415, 280]
labels_gender = ['Man','Woman','Man','Woman','Man','Woman','Man','Woman']
sizes_gender = [315,189,125,212,270,145,190,90]
weight_gender = [189,315,270,212,125,145,200,80]
colors = ['#ff6666', '#ffcc99', '#99ff99', '#66b3ff']
colors_gender = ['#c2c2f0','#ffb3e6', '#c2c2f0','#ffb3e6', '#c2c2f0','#ffb3e6', '#c2c2f0','#ffb3e6']
 
# Plot
plt.pie(sizes, labels=labels, colors=colors, startangle=90,frame=True)
plt.pie(sizes_gender,colors=colors_gender,radius=0.75,startangle=90)
centre_circle = plt.Circle((0,0),0.5,color='black', fc='white',linewidth=0)
fig = plt.gcf()
fig.gca().add_artist(centre_circle)
 
plt.axis('equal')
plt.tight_layout()
plt.show()
