[pstricks] stacked plot

[grivet]

Hi,
I am looking for a way to make up a so-called stacked plot using 
pstricks. I have a series of files, each holding a digitized spectrum
(intensity vs. frequency). Each spectrum was recorded under a different 
value of a parameter (temperature).

I wish to plot the lot in a single figure, spectrum #n being offset from 
spectrum #n+1, in x and y,  to give an impression
of 3D. Further, to make for a clearer plot, hidden lines should be 
removed, so that contiguous spectra do not tanglle together.

A rather involved example of what I am after is shown as fig 3 of

I would be grateful for any suggestion
