title: Gnuplot - Plot graph with continuously varying line color - plot with color fade / transition
body: <p>I am using GNU plot (gnuplot) to plot some output data from integration of a strange attractor (<a href="https://en.wikipedia.org/wiki/Attractor#Strange_attractor" rel="nofollow noreferrer">see Wikipedia</a>) - and as this is a strange attractor the line &quot;rolls around itself in 3D space&quot;.</p>
  <p>This makes it difficult to see what happens when plotting a lot of data. See this image: <img src="https://i.stack.imgur.com/ypPPm.png" alt="Lorenz System" /></p>
  <p><strong>Is there any way to plot a transitioning or fading color from say red at the start to blue at the end?</strong>  I know gnuplot is a powerful tool but perhaps I ask too much?</p>
