为 geopandas 图添加标签或位置

Adding label or location for geopandas plot

我创建了一个州及其所有行政位置的 geopandas 图。

map_df

这是我用来创建状态图的代码:

fig, ax = plt.subplots(1, figsize=(200, 100))
cmap = colors.ListedColormap(['red', 'blue', 'green', 'yellow', 'orange'])
bounds = [1,2,3,4,5,6]
norm = colors.BoundaryNorm(bounds, cmap.N)
ax.axis('off')
map_df.plot(column='Party', cmap=cmap, norm=norm,linewidth=0.8, ax=ax, edgecolor='0.8')
plt.show()

当前输出:

期望的输出: 整个地图将按以下方式标记:

我想更改此图像,以便 map_df['NAME'] 中的值标记在该管理位置的地块内。

如有任何帮助或建议,我们将不胜感激。

您可以像这样简单地添加一个标签

ax = map_df.plot(column='Party', cmap=cmap, norm=norm,linewidth=0.8, ax=ax, edgecolor='0.8')
ax.annotate(label, xy=(x, y), xytext=(3, 3), textcoords="offset points")

其中 label 是您要添加的与定义的其余变量一起使用的内容。有关更多信息,请参阅

我还建议使用 legends,因为文本可能会在面积较小的区域溢出。您可以在此处查看更多信息 - Customize Map Legends and Colors in Python
