3d parametric surface VI: I need some explanation

[gnappo]

I refer to the 3d graph which in input wants 2d arrays for x, y, z. 

Actually I cannot understand the Labview help, where it says: 

x matrix is a 2D array of data that determines the surface in relation to the x plane. (same for y and z)

I cannot understand what is the x plane. As far as I know x is an axis and not a plane. 

Could someone please explain to me? From Labview example codes I cannot understand. 

Thank you in advance.

There is an example in the example finder called "3D Parameteric surface.vi ", it is not that good, though.

There are plenty of tutorial on the web, for example this one.

See how far you get. 😉
