what kind of graph need to use?

[g.doraaa]

 I have this program, and I would like to change the Intensity graph to another graph, which represents  sin(3*x)*cos(5*y) function. This representation will be a paraboloid. Can u give me any idea how could I do that, please?

Learn about LabVIEW's 3D Graphs.  One way to get started doing this is to do a Web search for "LabVIEW 3D Graph".

I assume you want to keep (i.e. NOT change) the intensity graph, but just display different values in it.

The formula of a paraboloid is given here: https://en.wikipedia.org/wiki/Paraboloid) , so just change the formula and potentially the x and y ranges. Also  decide on values for "a" and "b". 

Is this "idea" sufficient for you?

Here's how it would look like if a=b=1
