#用饼形图来统计学生成绩等级占比

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

label=['A','B','C','D']
percent=[25,54,16,5]
#explode=[0,0.2,0,0]
explode=[0,0,0,0.1]
plt.axes(aspect=1)
plt.pie(x=percent,labels=label,autopct='%.2f%%',explode=explode,shadow=True)
plt.show()

#axes规定圆的形状，默认是椭圆，规定为1时就是标准的圆
#explode是规定每块饼突出的程度
#shadow就是开启阴影了
