构建一个显示的数值的函数，将plt.pie中的autopct=该函数即可。...代码：
import pandas as pd
import matplotlib.pyplot as plt
import matplotlib as mpl
mpl.rcParams['font.size...'] = 7.0 # matplotlib设置全局字体
# 创建两组数据
x1 = [30,25, 66, 13, 23]
x2 = [29, 28, 90, 19, 31]
x_0 = [1,0,0,0...] #用于显示空心
labels = ["Intron","Intergenic","UTR","Exon","CDS"] # 标签
colors = ["#FFDD55","#EE7700","#99FF99...))
# 同时显示数值和占比的饼图
return '{p:.2f}% ({v:d})'.format(p=pct,v=val)
return my_autopct
