I have seen plenty of threads on how to create multi-variable thematics on categorical data.
I would like to know how to create two thematics for a single point. E.g. Sales drives symbol color; SqFt of facility drives symbol size. I would like to have the software determine the natural breaks method of splitting these two variables into 5 categories each. This can't be too hard...MapInfo had this functionality but they still can't sort data tables!
