[Gnuplot-info] different colors on the same curve

[chedly g. <che...@gm...>]

Hello,
i want to plot a curve with different colors. For example, if the Xrange is
[0:500], i want that between [0:100] the curve is in red (for example),
between [100:200] the curve is in green, between [200:300] the curve is in
red again... and so on.
How can i do this?
thank you
