[Gnuplot-info] colour lines

[Tamas H. <ho...@gm...>]

I have a datafile containing x:y value pairs. I'd like to plot it so that
the colour of the line changes with the y value.
I'd like to colour it so that for every point of the curve it holds true.
(What I mean is that a line segment wouldn't be coloured according to the
end point, but would 'dynamically' change colour according to the current y
value of the point. Is it possible? Is it possible with 'smooth'?
