What I meant by a 'waterfall plot' in the document is a way of showing the evolution of spectral content of a data stream.

X is Time
Y is frequency
Z is fourier amplitude.

So a slice at fixed X is the power spectrum of the data in that time slice.
A slice at fixed Y is the time evolution of that spectral component.

Consult google for more information.  Most examples use 3d mesh plots, but kst would display them as an image, with Z as color.  I find this clearer anyway (though not as high-tech looking).
