Colorfunction along a line...

Hi, all,

   I have a series (several thousands) of data traces as read from an
oscilloscope. From these, I can extract the envelopes easily, and these
are the "raw" data with which I'll have to work.
   I'd like to be able to map a very long list of data onto a straight
line, and have the line's color be dependent upon some ColorFunction
(which I can define once I figure out what sorts of amplitudes will be
dealt with). Is there an easy way to do this using non-primitives? In
other words, if I have to define a line as a succession of colored
points, I will, but I'd rather just shove a colorfunction into a Line
(or a Plot[constant, {x, 0, 1}] ) routine.
    As an example (though not really exactly what I want to do, nor do I
see how to apply it to my problem), there's an example at
http://www.outbacksoftware.com/mathematica/mathematica-intro.html, about
halfway down that page, wherein a graphics object (a plot of several
sine functions) is colored according to the x-coordinate. However, I'd
like to map some other (perhaps many) hue values onto my lines.

 
             Thanks,
                   Curtis O.
