You are referring to Stata 7, it seems.
If you have several means and standard deviations,
you just need to use -range- to set a variable
with desired range and use the -normden()- function.
e.g.
clear
set obs 1001
range x 0 10
gen n1 = normden(x-5,1)
gen n2 = normden(x-4,0.8)
gen n3 = normden(x-6,1.2)
graph n? x , c(sss) s(iii)
