import numpy as np
import matplotlib.pyplot as plt
labels ='A','B','C','D'
fraces = [15,30,45,10]
plt.pie(x=fraces,labels= labels)
plt.show()

椭圆变标准圆  plt.axes(aspect=1)

import numpy as np
import matplotlib.pyplot as plt
labels ='A','B','C','D'
fraces = [15,30,45,10]
plt.axes(aspect=1)
plt.pie(x=fraces,labels= labels)
plt.show()

在图上显示所占份额autopct='%0f%%'

import numpy as np
import matplotlib.pyplot as plt
labels ='A','B','C','D'
fraces = [15,30,45,10]
plt.axes(aspect=1)
plt.pie(x=fraces,labels= labels,autopct='%0f%%')
plt.show()

突出重点，分离某一块explode= explode

import numpy as np
import matplotlib.pyplot as plt
labels ='A','B','C','D'
fraces = [15,30,45,10]
explode = [0,0.5,0,0]
plt.axes(aspect=1)
plt.pie(x=fraces,labels= labels,autopct='%0f%%',explode= explode)
plt.show()

实现立体感 有阴影 shadow=True

import numpy as np
import matplotlib.pyplot as plt
labels ='A','B','C','D'
fraces = [15,30,45,10]
explode = [0,0.1,0,0]
plt.axes(aspect=1)
plt.pie(x=fraces,labels= labels,autopct='%0f%%',explode= explode,shadow=True)
plt.show()
