OSMnx可视化在Folium上的边缘中心度图 [英] OSMnx Visualize the graph of edge centrality on Folium

问题描述

我正在尝试使用以下代码在边缘上绘制边缘中心度图

I'm trying to plot the graph of edge centrality on the folium using the following code

graph_map = ox.plot_graph_folium(G,
                                 popup_attribute='name',
                                 tiles='stamenterrain',
                                 edge_color=ec,
                                 edge_width=2)

其中，ec是边缘颜色的列表，但未显示. edge_color是否接受颜色列表?有什么想法吗?

where ec is list of edge colors but it is not showing up. Does edge_color accept a list of colors ? Any ideas?

如果您能帮助我，我非常感谢.

I really appreciate if you can help me.

推荐答案

我尝试将新的边缘颜色列添加到图形边缘的gdf

I tried adding a new column of edge color to gdf of the graph edges

gdf_edges = ox.graph_to_gdfs(G,
                             nodes=False,
                             fill_edge_geometry=True)
gdf_edges['edge_color'] = ec

然后修改两个功能

make_folium_polyline(edge, edge_width, edge_opacity, popup_attribute=None)

和

plot_graph_folium(gdf_edges, graph_map=None, popup_attribute=None, 
                      tiles='cartodbpositron', zoom=1, fit_bounds=True, 
                      edge_width=5, edge_opacity=1)

达到最终结果:
