It really wasn't what I was going for (and I would love -- if it's
possible -- a resolution of that), but it works. I was afraid that the
timing would be far too long for my datasets, but it looks doable:
data={#, .5+.5*Sin[417#]}&/@Range[0, .05, .0001]; (*
some--simple--sample data *)
toPlot={Hue[#[[2]]], Point@{#[[1]], 1}}&/@data; (* massage it a
bit: apply "Hue" to each ordinate, and wrap "Point" around the
{abscissa, 1} pair *)
Show[Graphics[toPlot], PlotRange\[Rule]All] (* show the
stuff *)
Cheers.
