3D Plot from multiple waves
Lars
after reading up on 3D plots I'm still kind of confused.
What I have:
Multiple waves with x-Scaling applied. The x-Scaling varies a little between each wave. Each wave also represents data connected to a certain wavelength.
What I need:
Some kind of 3D (surface) plot. Where I struggle is, how to form the needed matrix(?) where each column has a different x-scaling and also a selected z scaling?
Maybe someone can offer me a little help here.
With best regards, Lars
Do you actually want a "waterfall plot"?

To make a real waterfall plot your data must be in a 2D wave. You can have auxiliary 1D waves to specify the X and Y locations of the points but they must be the same for all traces in the plot. Thus in your case you would have to create a 2D wave by interpolating from your 1D waves.
A fake waterfall plot is just an XY plot that uses trace offsets to create the waterfall effect. It works with 1D waveforms or 1D XY pairs. A help topic on fake waterfall plots and an example experiment were added in Igor Pro 6.30. I also posted about it at http://www.igorexchange.com/node/2538.
I don't have an example of creating a Gizmo waterfall plot. Perhaps someone else can provide it.
