# Re: st: plot 3 normal distribution on one graph

```Dear Sylvain and Phil,
Thank you very much for your reply. It solves the problem! I always
test my codes line-by-line in the command window before writing it in
a do.file (because I like to call a variable by clicking on it ) and
did not realize it could make a difference.

Thanks!

Best,
Yannan
