Overlay Normal Curves

Hi:

I am trying to figure out a way to overlay multiple Normal curves on a single plot. I am familiar with only off the shelf proc's such as UNIVARIATE and PLOT, neither of which have this facility (at least I am not aware!!). I have tried univariate with little success as it does not have the 'OVERLAY' option that PLOT has, but I am not familiar how to plot a normal curve using PLOT. If there is a way to solve this please let me know.

Thanks!

Re: Overlay Normal Curves

Hi:
There's an example of plotting a normal density curve here (overlaid on bars):

and
http://ftp.sas.com/techsup/download/sample/graph/gchart-probplot.html
and using Graph Template Language:

and
http://www.mwsug.org/Conference/2005/Statistics/SS900.pdf

Since several of these examples involve advanced features, such as ODS Graphics and/or SAS/Graph and Annotate data sets, your best bet for help with this question is probably Tech Support.
