Overriding default palette

[Lenbok]

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.

Using this way, it reports errors.

I currently use this:

palettefile(n) = sprintf("<sed -e 's/set style line/set linetype/' -e 's/lt 1 //' /path/to/gnuplot-palettes/%s.pal", n)
load palettefile("dark2")

I currently use this:

palettefile(n) = sprintf("<sed -e 's/set style line/set linetype/' -e 's/lt 1 //' /path/to/gnuplot-palettes/%s.pal", n)

It works. Thanks!
