Gnuplot - Plot graph with continuously varying line color - plot with color fade / transition

Question

I am using GNU plot (gnuplot) to plot some output data from integration of a strange attractor (see Wikipedia) - and as this is a strange attractor the line "rolls around itself in 3D space".

This makes it difficult to see what happens when plotting a lot of data. See this image:

Is there any way to plot a transitioning or fading color from say red at the start to blue at the end? I know gnuplot is a powerful tool but perhaps I ask too much?

Answer 1

I found an answer here: gnuplot

# start value for H
h1 = 117/360.0
# end value for H
h2 = 227/360.0
# creating the palette by specifying H,S,V
set palette model HSV functions (1-gray)*(h2-h1)+h1,1,0.68

splot "output.csv" every 100 using 2:3:4:1 with lines linecolor palette title "Lorenz System"

The 4th argument after using is the color variable to use. In my case this is the time variable. (Col 1)
