Hi:   If you are running SAS 9.2 or higher, you can modify the PRINCOMP code directly to create an ellipse from your PRINCOMP procedure using the PLOTS= option.   Otherwise, as Doc suggested, if you want to make a dataset and then plot the points yourself, I find SGPLOT to be the most straightforward -- you only need a SCATTER statement and an ELLIPSE statement. Of course, with the PRINCOMP "direct" approach, you only need the PLOTS= option.   I believe that either one involves modifying the code a bit. The attached program makes some fake data then. shows both approaches. cynthia data testdata;    input grpvar $3.
