Hello:

I am interested in overlaying a 3D Scatter plot with a surface plot, where
the surface is a simple 45 degree plane (Y=3DZ) that is placed on the x-axi=
s.
Rob was nice enough to find two SAS exercises that generate these two types
of 3D plots.

How do we overlay them in SAS?

From Rob:

"

Hmm =85 ok, so it sounds like you=92re wanting a g3d scatter like this =85

With a g3d surface like this (but tilted at a 45 degree angle) =85

You could do one with SCATTER/PLOT and the other with annotate.

You can use proc g3d to generate both the 45 degree plane and the
scatter plot, then use proc greplay to overlay them. The trick
is to use 'WHOLE' template:

data hat;
   do x=-5 to 5 by 1;
      do y=-5 to 5 by 1;
         z=sin(sqrt(x*x+y*y));
   z1=y;
         output;
      end;
   end;
run;

proc greplay igout=gseg nofs;
delete _all_;
run;

proc g3d data=hat;
   plot y*x=z1;
   scatter y*z=z;
run;
quit;

proc greplay igout=gseg tc=sashelp.templt nofs;
template=whole;
treplay 1:g3d1 1:g3d;
quit;


Note the treplay 1: & 1:, since there is no other template.

Just noticed that axis ticker from plane also overlaid with scatter,
to avoid it, add the noaxis option to the plot statement:

proc g3d data=hat;
   plot y*x=z1 / noaxis;
   scatter y*z=z;
run;
quit;
