High quality 3d plot

[leonardolt]

Hi people!

I want tu put in my VI a high quality 3d surface plot, such as this one:

 The problem is the the 3d resources that come with LV are quite far from what I need. In my project I build a table with 4 columns: X, Y, Z, Signal. All of them are float values. From the picture in the example it can be seen that there is no reation between Z coord and the surface color. The color should be given by Signal column.

 So, do anybody know where can I find such thing? It could be a VI, a DLL or an ActiveX that I would call from the main front panel window.

 Thanks so much

The 3D surface plot has a color matrix input. That said, I'm not very familiar with it so I'm not sure if it does what you want.

Thanks for your reply, for(imstick).

 This color matrix imput did not really solve my problem, but it made me search for what it is used for. So, in one os these seaches, I found a post saying about "adding a 4th dimension" to a 3d graph. In that post I saw thar I can use the wMatrix property to control point's color individually.

The document about it is in: http://digital.ni.com/public.nsf/allkb/E09EB9C864A320CD862568890005B388?OpenDocument

Thanks at all!
