OSMnx Visualize the graph of edge centrality on Folium

问题

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)

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

I really appreciate if you can help me.

回答1:

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

Then modify two function

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

and

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

The final result is achieved
