Some time ago I discussed how to get the jet colormap from Matlab in gnuplot. Since Matlab R2014b jet is no longer the default colormap. Now parula is the new default colormap. It was introduced together with new default line colors.
The changes in the default colormap address some of the points that were criticized of jet by Moreland and corrected by his colormap.
A colormap similar to the original is stored in the
parula.pal file, which is also part of the gnuplot-palettes repository on github. An example application of the colormap is presented in Fig. 1.
In order to apply the colormap you can simply load the file.
parula.pal file also includes definitions of line styles. The first line styles (1-9) corresponds to the colors of the parula palette, the line styles 11-17 correspond to the new Matlab line colors, see Fig. 2.
set style line 11 lt 1 lc rgb '#0072bd' # blue set style line 12 lt 1 lc rgb '#d95319' # orange set style line 13 lt 1 lc rgb '#edb120' # yellow set style line 14 lt 1 lc rgb '#7e2f8e' # purple set style line 15 lt 1 lc rgb '#77ac30' # green set style line 16 lt 1 lc rgb '#4dbeee' # light-blue set style line 17 lt 1 lc rgb '#a2142f' # red
If you want to use only the palette and not the line colors, you should remove them from the
