To create transparency, I use the gnuplot backend with gnuplot version 4
and I print to an svg file which I then convert to pdf using Inkscape.

Maybe there are easier paths nowaday, this was the only reasonably
working one that I found two years ago, and it still works in one of my
scripts.

 graphics_toolkit ("gnuplot");
 gnuplot_binary("gnuplot4");
 print([fname ".svg"]);
 system(["inkscape --export-pdf=" fname ".pdf " fname ".svg], [], 'async');
