I have a question about consulting a 3D graph design

I have in my data:

Samples
Frequency axis
And the amplitude by sampling for freq

How would you present this data in a three-dimensional graph

Functions like surf are irrelevant because the Z axis does not depend on X&Y

Z is a known value

tnx :)

Example

You don't need to do that, it is just a way in which you can create some example data. You can just use the actual Z values.

I think the natural choice here is a spectrogram. Samples go along one axis, frequency along the other, and color is used to convey power. Look at some of the examples on the linked page.

The best way to explore plotting options is to select the variable in your workspace, then open the Plots tab. All possible options for that variable will be displayed. Expand the list to see them all. Find one you like and select it.
