### 1、普通的饼状图 ###

from matplotlib import pyplot as plt
    
    # 显示饼状图
    # label = ["test1","test2","test3","test4"]
    #
    # fracs = [20,30,40,10]
    #
    # plt.axes(aspect=2)
    # plt.pie(labels=label,x=fracs)
    # plt.show()

效果图如下

### 2、显示每个label的比例 ###

# 在图例中显示每个label的比例
    # label = ["test1","test2","test3","test4"]
    #
    # fracs = [20,30,40,10]
    #
    # plt.axes(aspect=2)
    # plt.pie(labels=label,x=fracs,autopct="%.0f%%")
    # plt.show()

效果图如下

### 3、可以让某个/某几个label离开圆柱体，可以设置距离，如果不离开，距离设置为0即可 ###

# # 可以让某个标签离开圆柱体
    # label = ["test1","test2","test3","test4"]
    # fracs = [20,30,40,10]
    #
    # # 这里的0.1和0.2就是离开的距离
    # explode = [0,0.1,0,0.2]
    # plt.axes(aspect=2)
    # plt.pie(labels=label,x=fracs,autopct="%.0f%%",explode=explode)
    # plt.show()

效果图如下

### 4、设置阴影效果 ###

# 可以让某个标签离开圆柱体
    # label = ["test1","test2","test3","test4"]
    # fracs = [20,30,40,10]
    #
    # # 这里的0.1和0.2就是离开的距离
    # explode = [0,0.1,0,0.2]
    # plt.axes(aspect=2)
    # # shadow设置阴影效果
    # plt.pie(labels=label,x=fracs,autopct="%.0f%%",explode=explode,shadow=True)
    # plt.show()

效果图如下
