proc sgpanel different marker sizes by group

[nvid]

I'm using proc sgpanel to create a scatterplot. There is a grouping variable, and I'd like one group (starfilled) to have bigger markers than the other group (circlefilled). Does anyone know how to do this? I can't find a styleattrs or markerattrs option for this. 

proc sgpanel data=have noautolegend;
  styleattrs datasymbols=(circlefilled starfilled);
  panelby visit / columns=3 novarname; 
  scatter x=xval y=yval / group=Group colorresponse=z;
run;

Look at DATTRMAP in the documentation.

It is a special helper data set that allows you to set properties for group variables such as marker and marker size based on the values.

Or search the Graphics Programming section of the forum for DATTRMAP for some examples.
