How to create multipule plots on one graph?

[Ken_oy]

Hi, need help,

I want to use PROC GPLOT to create (three plots, one page):

{ plot Freq*rd (when gp=1) } overlay
{ plot Freq*rd (when gp=2) } overlay
{ plot Freq*rd (when gp=3) }

I try the BY statement, but it gives me separated plots. How can I do that?
please see the dataset below
------------------------------------------
rd gp Freq

0.8 1 0.000
1.9 1 0.000
0.6 2 0.448
0.8 2 0.448
1.9 2 0.448
0.6 3 0.000
0.8 3 0.000
1.9 3 0.000


Thank you so much!! Message was edited by: Ken_oy

Hi:
You might look at the GPLOT examples of plotting multiple overlays in one PLOT output. For example, one way to plot multiple lines is to have:
[pre]
plot yvar*xvar=catvar;
...which for your example would seem to be...
plot freq*rd=gp;
[/pre]
