Color palettes for gnuplot

Color palettes for gnuplot

In order to use a palette load it at the beginning of your gnuplot file via

load 'palette.pal'

Replace palette by the name of your desired palette, which are listed below.
Note, that this will not only define a palette, but also overwrite the first eight line styles. If you want to use your own line styles, you have to define them after the above command.

If you need more help, have a look at this example.

Most of the palettes are from ColorBrewer and were first ported to gnuplot by Anna Schneider.

If you look for a good standard palette try moreland.pal, which comes from Kenneth Moreland.

gnuplot-palettes's Issues

Adding matplotlib colormaps

Hi,

Thanks for this great compilation!
I gathered the colormaps from matplotlib and brought it into the gnuplot format. However, I did not take the time to create the linestyles for the colormaps, except the viridis colormap.

If you like, you can add these colormaps to the others.

Best,
Stefan

Overriding default palette

It may be worth including as a note in the readme, that it's possible to use these palettes to override the default, so that line styles do not need to be explicitly specified in plot commands. The method I use is a pair of commands like this:

palettefile(n) = sprintf("<sed 's/set style line/set linetype/' /path/to/gnuplot-palettes/%s.pal", n)
load palettefile("puor")

These can be put in your .gnuplot file to take effect on startup, and you can then call the load palettefile to select a different palette when desired.

Of course, if there is a better way to accomplish this, it would be good to know.
