Bivariate thematic for continuous data

Discussion created by JohnGargiulo on Jul 26, 2013
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!
