That is not a standard terminology. It could mean either the graph of a function of one variable: y= f(x) in a cartesian coordinate system with one x-axis and one y-axis or (perhaps more likely what you mean) a function of two variables: z= f(x,y). To graph that you need three axes, x, y, z with the z-value (height of a surface above the xy-plane) given by f(x,y).

Also, could you bumb your explaination down for me since I'm a dumbask?
 
Are you talking about statistics or co-ordinate geometry. Your terminlogy does not make this thing atleast specific?

Raza:
Those on your image are called level set curves; each is characterized by a constant value of R^2

I have a project which states me to make a two-variable graph. This is for Data Management which is study for statistics. Are "Grade-10" and "Grade-12" variables?

So a 3D graph is a two-variable graph?

I believe that would be one way to put it!
