hi ... you got some good suggestions about GREPLAY (definitely take a look at Robert Allison's web
site)

here's an example with your data (I modified a few other portions of the SAS code too --- they are
just suggestions) ...

* use LIST input (there are spaces between variable values);
data aa;
input Month Year Lending delinquencies;
cards;
01 2002 5529 .025
02 2003 6574 .023
03 2004 7473 .021
04 2005 8747 .034
05 2006 12227 .011
06 2007 12449 .013
;
run;

* use a TrueType font, specify aspect ratio as square (800x800);
goptions reset=all dev=gif xpixels=800 ypixels=800 border ftext='arial';
