3d graph general question

[PerBorgvad]

Hi

I try to plot a logged file to a 3D graph and do not understand the arguments to the function

CW3DGraphLib__DCWGraph3DPlot3DSurface()

The function expects 2 vectors and 1 matrix. The x and y vectors are one dimensional arrays (such as x[100], y[100])

and the z matrix two dimensional (z[100][100])

I have three variables logged, they are all one dimensional x[100],y[100] and z[100].

In a example provided by NI, 3DGraphContours.cws, the call uses the x vector for both x and y vector. The values in x[ ] is -PI to +PI

The z matrix contains data generated by sin and cos.

My question : With 3 variables how do I call  CW3DGraphLib__DCWGraph3DPlot3DSurface()

Hi

I'' rephrase as my question was not formulated precisly :

Still asuming that the xData will be assigned to the x-vector and the yData to the y-vector.

As for the z-matrix I do not know how to fill the array to reflect z-values with respect to both x- and y-axis.

What shold be stored in z[0][0...99] , z[1][0..99] and z[...99][0....99] prior to the plot function.

Appreciate any suggestion
