Waterfall plots for signals not business in JMP?

martindemel

Hi,

a customer asked if JMP can create plots usually used in Signal Processing, like a waterfall plot as this:

You have multiple measurements (Samples) for different X-Vars (C(X kHz)). As it could have Kind of dirac steps it is a very stiff Problem the Surface Plot cannot handle very well. Also with the Scatterplot 3D I could not come to a equivalent representation. May I have to Play with shading, light, ....but I believe the Problem is something different. We would not be able to create such dense steps in the steep Areas like a stiff ODE solver would create.

Of course I could send the data to MATLAB and create this waterfall plot. The question is can I do this also with JMP alone?

Thanks for your thoughts,

Martin

What is the issue with Surface Plot? Too noisy? Too square? This is what I get after using a numeric rank for frequency to replicate the previous categorical treatment. (It's a question for the domain expert whether the frequencies should be spaced evenly or not.)

A scatter plot simulating heat map avoids some of the occluded feature issues.

I had to make it very wide, change the marker to a vertical line, and adjust the color scale to see the flare up near the bottom of the purple region. This does show a trough (green horizontal stripe) that I missed before. A true heat map would work about as well if you can accept the binning.

I can see it if I rotate the surface plot just right.
