I would very much like to plot / sketch / graph a 95% confidence ellipse using base SAS for a small data set I have, of size 9.

I'm unsure of how to proceed. This is the two methods I tried to use without much success:

proc princomp DATA=scores OUT=scores1 COVARIANCE plot=((alpha=0.05)=(confidence=ellipse));

title 'Scores:';

VAR x y ;

RUN;

and

proc corr data=scores nomiss plots=scatter(ellipse=prediction alpha=0.05);

var x y;

run;

Anyone have any ideas? Also, if you know of another statement to add to any code to provide me with the individual c.i. for the two variables, I would greatly appreciate that as well.
