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 hydrants and the polygons are districts within a county. Can I symbolize the polygons, in graduated colors, based on the number of hydrants reported in that district?
I can't use the actual point data of the table.
I hope this made sense. I'm open to programming solutions if anyone knows of anything. Thanks.
