I have a layer of polygons joined by a relationship class to a table by Field = DistrictIDNumber
The Table has multiple entries for each polygon so it is a one to many relationship.
Is there any way to symbolize the polygons based on count of related entries? Lets say they are number of observations and the polygons are districts within a county. Can I symbolize the polygons, in graduated colors, based on the number of observations reported in that district?
I can't use the actual point data of the table.
I'm currently using ArcGIS 10.2 but have access to R, if you guys think this would be a more appropriate application.
