[Plplot-general] vari-colour 2D plots

[<si...@mu...>]

Is there a method of plotting a 2D line graph, where the colour of the
line varies along its length?

In GnuPlot this could be done with the 'linecolor rgb variable' macro, for
example (which causes the line to change between 3 colours representing
lock state):
plot "484799.059" using 1:5:(stringcolumn(2) eq "L1_INT" ? ($6==1 ?
rgb(0,255,0):rgb(255,0,0)) : rgb(220,220,220)) with lines linecolor rgb
variable title ""
