Arrows between subplots（1个答案）

我目前有两个子图，一个饼图和一个条形图，我想知道是否有一种方法可以添加一条线或箭头来表示饼图的红色部分是指堆叠条形图。
从这里：

对此：

这是我目前为止的代码：

opfig, (ax1, ax2) = plt.subplots(1, 2, figsize = (12,6), dpi=80)

percentage = operator['Percentage']
labels = operator['Operator']
explode = (0,0,0,0.1)

label = [f'{lab}, {per:0.1f}%' for lab, per in zip(labels,percentage*100)]
ax1.pie(operator['Count'], explode = explode)
ax1.legend(labels=label, title='Operator Type')

militaryPer = military['Percentage']
militaryLab = military["Military"]

bottom = 1
width = 0.2

for j, (height, label) in enumerate([*zip(militaryPer, militaryLab)]):
    bottom -= height
    bc = ax2.bar(0, height, width, bottom = bottom, color="C0", label=label, alpha=0.1+0.25*j)
    ax2.bar_label(bc, labels=[F"{height:.0%}"], label_type='center')

ax2.set_title('Military Operators')
ax2.legend(loc='lower right', prop={'size': 10}, borderpad=1, framealpha=0.9)
ax2.axis('off')
ax2.set_xlim(-1.5 * width, 1.5 * width)

plt.show()
