I currently have a point feature class that has a couple of attributes that I want to use to symbolize its layer. One of the attributes is called ExceedsTolerance, which either has "Y" or "N" for its value. The other attribute is called Measure, which has the values -2, -1, or anything from 0 and greater.
I know that I can create a layer definition that has different symbols for unique values for each attribute. For instance, I can have a black box for Measure when the value is -2, an orange circle for when the value is -1, and a blue circle for when it is greater than or equal to 0. The same idea goes for ExceedsTolerance.
What I would like, however, is to have it where it shows a certain symbol when ExceedsTolerance is "Y" no matter what the Measure is, but when ExceedsTolerance is "N" to show whatever I have set for Measure. I can somewhat do this with the Multiple Attributes section of the Symbology tab in the Layer Properties, but I can't do it with the case where Measure is greater than 0 and ExceedsTolerance is "N". How would this work in ArcMap and is it possible?
