为大熊猫图添加标签或位置

Question

我创建了一个州及其所有行政地点的地理熊猫图。

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：

所需的输出：将整个地图标记为以下方式：

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

任何帮助或建议将不胜感激。

您可以像这样简单地添加标签

fig2 = plt.figure()
ax = fig2.add_subplot(111, projection='3d')
ax.scatter(Ret.x_edge[0:25], Ret.y_edge[0:25], Ret.statistic[16], c=Ret.statistic[16])

其中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") 是要与定义的其余变量一起添加的内容。有关更多信息，请参见here。

我也建议您使用label，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
