OSMnx可视化Folium上边缘中心性的图形

Question

我试图使用以下代码在folium上绘制边缘中心图：

Select tbl.* From myTable tbl Join ( Select item_code, max(price) as mx, Round(max(price)*.75,0) as mx75 From myTable Group by item_code) tab On tbl.item_code = tab.item_code And tbl.price between tab.mx75 and tab.mx Order by 1, 4

其中ec是边缘颜色列表但没有显示。 edge_color是否接受颜色列表？有什么想法吗？

如果你能帮助我，我真的很感激。

Answer 1

我尝试将新的边缘颜色列添加到图形边缘的gdf

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 =＆＃39; cartodbpositron＆＃39;，zoom = 1，fit_bounds = True，                         edge_width = 5，edge_opacity = 1）

取得最终结果
