This is a very interesting suggestion, I will work on.

You can probably create a triangular mesh (start reading here) for all existing XY points while initially ignoring Z, then add the actual z as a last step.

LabVIEW even includes a tool for points in a plane. Try it!

Here's a quick example:

Dear Altenbach,

your support and solutions are very helpful.

I am going to study all your new suggestions. 

Thanks,

The original dimension is visible in min and max values (red dots in "3D points" graph).

Changing the number of samples it changes also the original dimension.

For example, in test2.vi now samples= 200 and "3D Intensity map" or "waveform graph" are both 200.

Modifying samples both graphs follow this number.

Is it possible to modify samples maintaining always the original dimension in "3D Intensity map" or "waveform graph"?

[altenbach]

You can change the multiplier of the x and y axes. By default, the markers correspond to the array index, but you can apply any other scaling.

[altenbach]

Here's how that would look like (simplified). (I am not sure how you messed up the z scale)

[M_Ricci]

The problem is that with samples= 400, the result is image A.
With samples= 50, the result is image B.

I found it is not related to the graph scale, pheraps in Graph2 it is more clear what happens changing samples:

Z remains the same (144.06) while XY changes.
While XY extremes must have always the same value of "Interpolate 2D Scattered" Xi or Yi extremes.

... and they do. You don't show how you generate the grey 3D surfaces, but X and Y must of course be based on the ramp, not on array indices.

I don't understand why are you still messing with the scattered interpolation instead of the triangular mesh.
