Hi, everyone. For a school project, I will need to allow my map to display the function of showing the distances of the different places. I came by a lot of discussion thread about how to do, but I am quite confused about it. Plus, I would need it to look like Joshua Milligan's map: Mapping Distances – An Alternate Approach | VizPainter .
I am quite confused about the calculated field and using Lookup function to find the distances. Hope that someone could give some help!
Hello - To find distance between two points you need two sets of Lat and Lon. Now in your case Point 1 would be cities and Point n would be other cities. You can get the formula of distance and then allow user to select the city first and filter on the distance.
The following kb article should be the starting point to build such dashboards:
