I think that you can use IDL's GAUSSINT() function to do this.
e.g., X = GAUSSINT( (findgen(N)-(N-1.0)*0.5) / ((N-1.0)/(SD*2.0)) ) will
give you what you want over +/- SD standard deviations (N points
worth). You would then use such an X vector in your plot, instead of
just a straight findgen-style X vector.
