[Gnuplot-info] Dynamic line colors

[BBands <bb...@gm...>]

Good morning plotters,

I'd like to vary the color of a line according to its slope, say green
when rinsing and red when falling. Is this possible?

Thanks,

BBands

it's possilbe using the 'linecolor palette' option.

# if you want to plot a function start here:
set table 'data'
plot sin(x)
unset table
# if you want to plot data start here:
temp = 0
plot 'data' using 1:2:(last=temp,temp=$2,$2>last?1:-1) with linespoints
linecolor palette

Though I have been actively plumbing the depths of gnuplot and its
community for more than a decade, it always proves to be a deeper well
than I know.
