Proportional Circle Maps in GeoMedia
Posted by jeffhobbs on March 26, 2008
Had a very interesting question today on the Directions Magazine GeoMedia list.
Hi fellow ‘GeoMediars‘.
One of my colleagues has asked me about the possibility of doing proportional circles maps in GeoMedia.
Since I don’t know if/how it’s possible, I come once more seeking your help, asking if anyone has ever done this kind of maps?
Best regards
Jorge
There were a few replies. However I did want to highlight one from Phil Hardy as I thought his attached diagrams were very good. He did make sure to let me know that he didn’t create the images himself…so he can’t take all the credit 
1) OK, by Proportional Circle map I assume you mean something like this.
2) First, use Functional Attributes to create centerpoints.
3) Then use the legend to change the style of the centerpoints. In this case I assigned size based on the Population attribute.
4) And the end result:
Simple, but I thought very well diagrammed. It should also be noted that a nice example of this can be seen on the USSample.gws that comes with every version of GeoMedia and GeoMedia Professional in the GeoWorkspaces folder.

It is another way - centerpoint + atribute base symbology - 1 legend entry, no thematic
