All you need to do is create a variable that identifies you points. In the
example below, I call this "TYPE". Then create a copy of your points and
give  type a different value. Use the plot statement form

Plot Y*X=Type

and with the proper smbol statements, one set will have the regression line
fitted and the other will have the individual points plotted. Try running
the following example

Data Points;
     input x y;
       cards;
1 2
3 5
7 22
9 12
run;
Data Plot;
    set points;
      type = 1;
      output;
      type = 2;
      output;
run;
Proc Sort data = points;
    by type x;
run;

Proc Gplot;
    plot Y*X = type;
      symbol1 c=red i = rl;
      symbol2 c= green v=star i = join;
run;
quit;

Dear SAS users,

Hi, I want to use proc gplot to draw a regression line but want to add
a x=y line  to the plot.

Can you inform me a good simple way?

thank you,
claus
