I believe that the following blog post contains a good example of filtering by radial distance in a view.
Hope this helps!
I tried that post but am having trouble with the distance filter. Im not sure if the distance is calculating from the mall coordinates as the origin. Do you have an idea of how to create a distance filter so I can filter around each mall to show the zip code coordinates that fall around 5, 10, and 15 miles from each center point? Im adding the files and workbook that Im currently playing with. Thank you!
