I would like to assign gnuplot to
.gnuplot files (gnuplot scripts) on Windows 8.1, in such a way that the gnuplot environment starts with the script file loaded.
For this I would need to pass the path of script file to
wgnuplot_pipes.exe. Unfortunately I cannot find any documentation about gnuplot command line arguments on Windows.
The closest I could find is a way to automatically render a .gnuplot file from the command line:
wgnuplot_pipes.exe -persist test.gnuplot
