I am displaying my county data (no. of cases) by finding the mean center of each county and displaying the mean center point as a single symbol by my chosen value. (Properties, Symbology, Advanced, Size, Size points by value x). How is the size or area of the circle calculated? Is my value the radius or diameter? I have chosen to display by this method so I can use transparency.
Thank you very much
I did not use proportional symbols because I wanted to be able to make the layer transparent. Is there a way to make a layer with proportional symbols transparent?
