可以通过matplotlib实现
from matplotlib.patches import ConnectionPatch
#制画布fig = plt.figure(figsize=(9,5.0625))
ax1 = fig.add_subplot(121)
ax2 = fig.add_subplot(122)
fig.subplots_adjust(wspace=0)
#大饼图的制作
labels = newdata8.index
size = newdata8.quantity
explode=(0,0,0,0,0,0.1)
ax1.pie(size, autopct='%1.1f%
