st: graphing two normal curves

["Elizabeth Allred" <lizard@hsph.harvard.edu>]

I'm trying to draw two normal curves with this command.

twoway function y=normden(x,0,1) || function y=normden(x,0.3,1), range(-3 3)

What I get is the complete second curve (with mean 0.3) and a small bit of the first--just the piece from x=0 to about x=1. Why am I not seeing both curves?
