Work around: everything exactly as you anycodings_gnuplot show but add an invisible plot component anycodings_gnuplot that uses the palette. Use set arrow from 22,1590 to 523,1090 filled back lw 3 lc rgb 'blue' Share answered at 14:20 Christoph 46. Well maybe it looks at a few anycodings_gnuplot other things also, but apparently not at anycodings_gnuplot arrows. Usually the order of arguments doesn't matter in gnuplot, unfortunately in your case it does. Each of the label types in gnuplot also allow for. It looks only at the plot anycodings_gnuplot itself. Axis labels and keys are set with rather straight-forward command types. set title Hello, world plot title set xlabel Time x-axis label set ylabel Distance y-axis label labels set label 'boiling point' at 10, 212 key/legend set key top right set key box set key left bottom set key bmargin set key 0. set arrow can be used to draw arrows or line segments in a plot. Your script is correct, but the program anycodings_gnuplot doesn't notice the presence of anycodings_gnuplot palette-colored arrows when deciding anycodings_gnuplot whether or not to activate palette anycodings_gnuplot processing. The first command tells gnuplot that you want to plot parametric curves. Suppose that we set a vertical line with set arrow from 1,graph 0 to 1,graph 1 nohead lt 0 Now, if I want this to be in the key, I can just plot a line with lt 0 but specify the y-value as 1/0.

You can take advantage of this to plot what you want. Thank you for anycodings_gnuplot the excellent report. 3 Gnuplot will ignore anything with an invalid value (1/0 for instance).
