您可以将DataFrame.plot.pie 与T 转置数据帧一起使用:
df = pd.DataFrame({'beer':[1,2,3],
'spirit':[4,5,6],
'wine':[7,8,9]}, index=['Africa','Asia','Europe'])
print (df)
beer spirit wine
Africa 1 4 7
Asia 2 5 8
Europe 3 6 9
df.T.plot.pie(subplots=True, figsize=(10, 3))

这是代码,我发现这种更灵活
from matplotlib import pyplot as plt
import pandas as pd
df = pd.DataFrame({'beer':[1,2,3],
'spirit':[4,5,6],
'wine':[7,8,9]}, index=['Africa','Asia','Europe'])
df= df.div(df.sum(axis=1), axis=0)
fig, axs = plt.subplots(nrows=df.index.size, ncols=1, figsize=(7,7))
fig.subplots_adjust(hspace=0.5, wspace=0.05)
for row in range(df.index.size + 1):
fig.add_subplot(axs[row] )
plt.pie(df.loc[df.index[row],:], labels=df.columns)
plt.axis('off')
