将图标添加到matplotlib绘图饼图

import matplotlib.pyplot as plt

data = [10, 30, 20, 40]

labels = ['A', 'B', 'C', 'D']

icons = ['path_to_icon1.png', 'path_to_icon2.png', 'path_to_icon3.png', 'path_to_icon4.png']

plt.pie(data, labels=labels, autopct='%.1f%%', shadow=True, startangle=90, wedgeprops={'edgecolor': 'black'}, textprops={'color':'black'}, radius=1, pctdistance=0.85, counterclock=False, center=(0, 0), frame=True)

for i in range(len(icons)):
    img = plt.imread(icons[i])
    imagebox = plt.OffsetImage(img, zoom=0.15)
    ab = plt.AnnotationBbox(imagebox, (0, 0), xycoords='data', frameon=False)
    plt.gca().add_artist(ab)

plt.show()
