Hi Liz,
Because the range for the first plot defaults to (0,1). Use a range(-3,3) option fir both and all will be well.

Subject: st: graphing two normal curves
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?
Elizabeth
