Symbolize features based on values in a related table

February 16 2011 | 0 comments

We would like to symbolize a point feature class with graduated symbols based on how many entries there are for each feature in a table with a one-many relationship. Is it possible to symbolize features based on a related table?

To be more specific, we have a feature class that represents trap locations and a table that lists trapped animals. Some traps have no animal records, some have many. We would like to symbolize the traps based on productivity, but we would like to have that be a dynamic update as we continue the trapping effort.
