You can do one of two ways. Radar supports acrossvar= option.
or you can use pdf option of columns=2, here is an example with ods pdf using gchart:
ods pdf columns=2;
proc gchart data=sashelp.class;
ods pdf close;
While you may be able to build radar charts in SAS, they are a very poor and most confusing way to transfer information. Visit www.perceptualedge.com and search for radar charts to see superior alternatives.
Just wanted to point out that Bill is talking about radar charts in general ... not specifically SAS radar charts! (right Bill?) :-)
ps - if all goes according to plan, there will be some nice enhancements to the SAS radar chart in v9.3 (I've been trying these out this past week, and they give the user a lot more control over the axes/spokes of the radar chart, etc ... it'll be a while before v9.3 ships, but be on the lookout for radar enhancements when it does!)
