[Gnuplot-info] Re: different colors on the same curve

[Gavin B. <gav...@ya...>]

Hi, 

Its really very simple (although you might run out of
colours if you have 'tens of files') You split it up
just as someone mentioned, but like this:

plot 'data.dat' u 1:(x<100?$2:1/0),/
'' u 1:(x>100&&x<200?$2:1/0),/
'' u 1:(x>200&&x<300?$2:1/0),/
'' u 1:(x>300&&x<400?$2:1/0),/
'' u 1:(x>400&&x<500?$2:1/0),/
'' u 1:(x>500&&x<600?$2:1/0)

for example would allow you to plot the sections as
different plots. You  can specify colours using the
with line (w l) option from plot (see help plot), but
this is going to depend on which terminal your using. 

Hope this helped,

Gavin.
