3D surface plot

first of all, I am using Labview version 8.5...and Ive only used labview for a couple weeks...had no training, pretty much just self learned so Im still new to labview..if I can get help from somebody here~ I would be really appreciate that~ and here are my problems:




1. Im trying to plot all the point in 3D plot and gives the blade shape graph; however, the line in the 3D plot connected all the points, and I would like a surface image   of the blade...



2. And a numeric control I can input the offset ...for instance..input z=1.5 then the program will pull out the cross-section point between the blade and the z=1.5 plane



THANKs for all the help~

Why don't you try the 3D Surface Graph?

Just drop the 3D Surface Graph down on the front panel, and LabVIEW will generate some block diagram action.

Connect an x and y vector (each is 1D array of values) and then a z matrix (2D array of values.)

I think I had try that before, but it didnt work...maybe I didnt give the right format to the Surface graph

so just simly add the output to the mathscript and change ''a''  ''b'' to 1D array, and change ''c'' to 2D array?

Gotta try that~


thanks for the help~

I would load the values from a file instead of using a mathscript.  Can you post a data set so I can play around with it?

Why do you want to use 3D Graph if the graphs are purely 2D?

there are 3 sets of points in the excel file..for z=0 , z=1, and z=2


and they are in (x,y,z) coordinate

But, since the z coordinates are constant within each data set, why not just graph them all on an xy graph in three different colors?
