Folium Choropleth“ key_on” issue

问题描述 投票:2回答:1

我有一个关于大叶中的Choropleth函数的问题。

state_data = pd.read_csv('data.csv')

mssp = folium.Map()

folium.Choropleth(
    geo_data='geodata.geojson',
    name='choropleth',
    data=state_data,
    columns=['District', 'Rooms'],
    key_on='feature.id',
    fill_color='YlGn',
    fill_opacity=0.7,
    line_opacity=0.2,
    legend_name='Rooms'
).add_to(mssp)

folium.LayerControl().add_to(mssp)

mssp

我的CSV:

    Price,Condo,Size,Rooms,Toilets,Suites,Parking,Elevator,Furnished,SwimmingPool,New,District,NegotiationType,PropertyType,Latitude,Longitude
930,220,47,2,2,1,1,0,0,0,0,Artur Alvim,rent,apartment,-23.543138,-46.479486

我的GeoJSON:

    {
  "type": "GeometryCollection",
  "geometries": [{
      "type": "MultiPolygon",
      "id": "Artur Alvim",
      "coordinates": [
        [
          [
            [-46.501092999999997, -23.545874999999999],
            [-46.501199999999997, -23.545991999999998],
            [-46.501261, -23.546139],
            [-46.502249999999997, -23.54945]
          ]
        ]
      ]
    }
  ]
}

我尝试了几种不同的'key_on'值,但是没有任何效果。它只是绘制区(为便于阅读,我在GeoJSON中省略了一些坐标,但这没关系)和图例。

[如果有人能提供帮助,尤其是向我解释这一点,我将不胜感激。

[How the output currently looks(在价格列中选中价格,但客房也不起作用)]

另外感谢!

从以下位置修改key_on参数:

key_on=feature.id 

key_on=feature.geometries.id 

[idgeometries下,因此您也应该放在这里。
