remove extra labels/keep certain labels for graphs

[Xianli Wang]

Hi all,
I want to draw multiple lines in one graph. Actually, I have more than 30 lines.
At first, I want to label all of the lines. And the code is like
legend(label(1 "") label(2 "")... label(30 ""))
But later I found out that Stata only label at most 15 lines.

So, I tried to remove labels for most of the lines, but keep 2 or 3 important ones.
I don't know how to do this.
legend(off) seems to remove all labels.

Does anyone know how to do this?
Thanks in advance.

Also, I realized that I can always do what I want in the graph editor.
I'm just wondering whether I can do it through do.file
Thanks a lot!
