This post shows you how to run PROC SGPLOT, create smooth curves by using penalized B-splines, use ODS OUTPUT to create an output data set from PROC SGPLOT, and process it to display drop lines.
SAS 9.3 already has smooth (anti-aliased) lines in SAS/GRAPH device=png output, and in SAS 9.4 you will also get smooth lines in your device=gif output (and gif animations)! Woo-hoo!!! Here are a couple of simple examples to demonstrate: The first example is device=gif Proc Gmap output. If you look very closely, you'll notice that
