Hi Alex,

an you possibly save it as a labview 2009 file?

best regards

sure,

btw: the vi attached is mainly based on the"National Instruments\LabVIEW\examples\analysis\plat-intp2Dxmpl.llb" example.

Hi,

You can see the problem with Alex his example again, I will have to make up data for points in the x-y mesh which are actually not part of my surface, oherwise I will get a skewed picture. For adding colours, Ben's car example gives a start I think:

thx for the link, in the meantime I re-used Sam Rogers idea, as it's based on a 3d scatter plot:

-----------------------

please explain "irregular shape" --- where's the problem with rectangles?

it should be always possible to fit an irregular shape in a rectangular bounding-box;

moreover,

when you change  the interpolation method for example to "linear" instead of "nearest" and look at Zi

the cell's which are not part of the surface contain NaN

Alex

Hi,

I rearranged the data in 2D-arrays to get the correct surface. I added NaN to non existing Z-points. How can i scale the plot? I know I can hit XY, YZ, XZ plane and scale it myself, but if I make the scale smaller, ie 200, you can still see the surface higher than the scales. Is there any control I can add, to atomatically scale it in a proper way.

I am trying to get the 4D plot now like Ben

Best regards
