python - 如何避免 Matplotlib 圆环图上重叠的楔形下降标签？

Question

我有以下圆环图:

正如您在图片中看到的，当楔形下降的百分比小于 3% 时，百分比标签开始与它们的邻居重叠。

问题:

如何在保持图表上的百分比标记的同时缓解或避免此问题？

最小可重现示例:

import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10, 10))

data = {"Category":["Housing","Groceries","Subscriptions","Rectreation","Other","Health","Transport"],
"Amount": [918.39, 546.20, 289.62, 60.59, 39.74, 19.99, 19.60]}

colors = ["#67b7dc", "#6794dc", "#6771dc" , "#8067dc" , "#a367dc","#67b7dc","#6794dc","#6771dc"]
df = pd.DataFrame(data)

ax.pie(df["Amount"],
            labels=df["Category"],
            autopct='%1.1f%%',
            wedgeprops=dict(edgecolor=  "white", linewidth= 1.5, width=0.3),
            startangle=270,
            colors = colors,
            pctdistance=0.85,
            labeldistance=1.2,
            textprops={'color':"w", 'fontsize': 14} )

ax.axis('equal') 
ax.legend(loc = 'center', prop={'size': 15})

plt.show()

Answer 1

当您处理静态图像时，似乎没有什么神奇的方法可以避免这种情况。我最终使用了 Plotly因为它允许您将鼠标悬停在小楔子上并查看百分比，即使百分比太小而无法显示。
