Plot a butterworth filter in 3d

[christophe.A]

Hi everyone,

I would like to know how to plot in 3d in LabVIEW and use it for a butterworth filter. I show it in 2d for different orders.

With matlab, I use commands like meshgrid and surf to plot it automatically in 3d. Can I do it the same with LabVIEW commands naturally ? I use the 3d plot helper but it asks for the z matrix, which i do not specifically know.

Thanks for your answers!

Hello.

Here's an example that shows how to plot lines and points on a 3D graph:

I hope this helps you.

Hi!

Thanks for your suggestion but it does not help. I do not have the Z matrix.

In fact, I have the shape of the 2D signal (butterworth nth order filter) and I want to plot it in 3D. I thought about a rotational shit of 360° but it seems a bit complicated. Is there any function that could help ?

See screenshots of the 2D signal and its 3D representation that I would like to obtain.

Thanks in advance,
