如何获得最大的气泡蟒蛇的半径以散乱地打开街道地图? [英] How to get the radius of the biggest bubble python plotly open street map?

问题描述

要进行进一步的分析，我想获得最大气泡的半径?最好能得到具有气泡半径的另一列.

To do my furthur analysis i want get the radius of the biggest bubble?it's better if I can get another column with a bubble radius.

当前代码:

fig = px.scatter_mapbox(df, lat="GPSLat", lon="GPSLng", zoom=15, height=500,width=1000,
                        size="Count",color="Device",title=' All device :2021/01/08')
fig.update_layout(mapbox_style="satellite") 
fig.show()

df:

Device  GPSLat  GPSLng  Count
1001    6.8050  80.0154 9.0
1001    6.6050  80.2154 12.0
1001    6.7050  80.4154 114.0
1002    6.8050  80.0154 2.0
1001    6.5050  80.0154 2111.0

推荐答案

如所评论，直径或半径将自动计算和绘制.如果您获得工程图数据，您将看到气泡大小基于您的计数".

As commented, the diameter or radius will be automatically calculated and drawn. If you get the drawing data, you will see that the bubble size is based on your 'Count'.
