Hi everybody! I am an Origin newbie. I am trying to plot a 3d surface over a nonuniform XY matrix. I have a set of XYZ points and I want to plot a surface interpolating them. As a simple example, let's say that my points are:
X | Y | Z
-5|3.1|-2.1
-5|2.6|-1.9
0 |3.2|-3.3
0 |2.7|-2.5
0 |2.2|-2.0
5 |3.1|-4.0
5 |2.6|-3.5
5 |2.1|-2.8
5 |1.7|-2.1
Moreover, my Z values are representing a logarithm, so I can not use a simple linear interpolation which would give me positive values. I do not know if it could be possible to truncate the surface for example at Z=-1.8. Thank you very much in advance.

Hi,
Please see whether the app works for you. It is to create XY data at specific Z values from 3D surface plots.
