Z(x,y)=A*x+B*y+C (A, B, and C are constants.)

X(u,v)=u
Y(u,v)=A*u+B (A and B are constants.)
Z(u,v)=v

Hi asmodel,

If the plane is NOT parallel to the Z axis, you can select
"File: New: Function Plot: 3D Function Plot" menu, and enter the function form:

Z(x,y)=A*x+B*y+C (A, B, and C are constants.)

If the plane is parallel to the Z axis, you can select
"File: New: Function Plot: 3D Parametric Function Plot" menu, and enter the function form such as:

X(u,v)=u
Y(u,v)=A*u+B (A and B are constants.)
Z(u,v)=v

Note that the 3D Function Plot is available in Origin 8.6 or later, the 3D Parametric Function Plot is available in Origin 9.0 or later.

Hope this helps.
