SAS Graphs 3D

[KafeelBasha]

Hello

%let r=2;

data sphere;
do u=0 to 2*constant("pi") by 0.02;
x=&r*cos(u);
y=&r*sin(u);
z=&r;
output;
end;
run;

title "Sphere";
proc g3d data=sphere;
plot y*x=z;
run;

When I run the above code I am getting plan,unable to see 3D plot. Please help.

Works fine for me.  In Base SAS, run the program, then look at the Results tab, lower left, and there should be G3d: Sphere output.  Or do you mean the graph is not showing any points, well thats probably twofold.  Firstly you have no z axis data other than one variable, hence it will be flat at 2.  secondly you would need to use the proc g3grid first on the data.  Try this program.  I randomly create z (height) to show an output:

data sphere;
  call streaminit(123);
  do u=0 to 2*constant("pi") by 0.02;
    x=2*cos(u);
    y=2*sin(u);
    z=rand("Uniform");;
    output;
  end;
run;

proc g3grid data=sphere out=sphere2;
   grid y*x=z / spline;
run;

title "Sphere";
proc g3d data=sphere2;
  plot y*x=z;
run;
