David has a good idea to start, but it turns out that the SURFACE routine
actually makes this type of plot VERY simple. Here's David's code hacked to
use it.

PRO Waterfall

; Create the data.

seed = 1L
data = FltArr(6, 101)
FOR count = 0, 5 DO BEGIN
row = RandomU(seed, 101)
FOR j=0,4 DO row = Smooth(row, 3)
data[count, *] = row * 30
ENDFOR

; Display window

Window, XSize=300, YSize=500

; Draw the plots.
surface, data, ax=70, az=0, /horizontal, /upper, zaxis=-1
END
