I am trying to symbolize features based on the "Unique values, many fields" Category in the Layer Properties menu. I have a feature layer that is supposed to have 2 fields with unique values to that feature. Can I symbolize features based on whether or not a certain combination of these unique values appear more than once.
For instance, if this was my table
FID Unique value 1 Unique value 2
1 X A
2 X A
3 S B
4 S C
5 M O
6 D O
7 V T
8 G F
Then I would want FID's 1 & 2 to be symbolized in the "both match" symbology class, FID's 3 & 4 to be in the "Unique vale 1 matches" symbology class, FID's 5 & 6 to be in the "Unique vale 2 matches" symbology class, and FID's 7 & 8 in the "Completely unique" symbology class. Is this possible at all?
I'm dealing with 100's of thousands of records, so I will not be able to do this manually via "Unique values, many fields" symbology protocol.
Thanks!
You could run Dissolve—Help | ArcGIS for Desktop with a count field then symbolize your feature class
