How to plot overlaying normal distributions

[Sam Harford]

Hi all,

I'm trying to do something for which I can't really find any previous posts. Basically, I want to create a single graph with two overlaying standard normal distributions. The thing is that I want the two distributions to have the same mean, but a different standard deviation.

Thanks a lot.

You can test transparency in the process:

Something like this?

twoway function y = normalden(x, 0, 1), range(-3 3)|| function y = normalden(x, 0, 2), range(-6 6)

Twoway graphs have a handy ability to graph functions which will be useful here. See -help twoway function- for more info.

Thanks Andrew and Leonardo for your helpful answers, it works now!
