I'm having some issues trying to plot 3D data.Ideally, I would like a surface plot, but I'm not sure I'm going about it correctly.I have three 1D arrays of equal length: x, y, z. The '3D surface graph' vi wants inputs of:- x vector- y vector- z matrix I dont have a z matrix, I have an array.So instead, I am using '3D line graph'.I only want to see the points like this: But I am getting this: The only way I got the top image is if I was dragging the plot around with my mouse.Does anyone know how to remove the lines, so only the points are plotted?Or better yet, how I could make a surface plot without a z-matrix?

Ya? I'm not sure what the deal is with that bump... Oh, and it's rotated. I just assumed the first column was x then y then z. Message Edited by elset191 on 08-17-2009 03:00 PM

XYZ graph

Solved!

Because what i used for the x axis isn't acutally the same for all three rows of z data, the graph is precisely what you had in mind. But, it's pretty close. After all, everything is less that .0006
