How about Using graduated symbols—Help | ArcGIS for Desktop . The proportional symbol size will be the controlled by the values of the attribute table.
Garland, are you saying you want to have the polygon symbology change as you zoom in or out? Change in what way and what software are you using?
I want to symbolize polygons that have almost identical spatial locations (still need to figure this part out, other than a dissolve)with a symbol in the middle rather than an outline or a fill to denote an area that needs attention to the end user.
I can make this work. Thanks for the responses!
