script.gp:
~~~~~~
print "entering script ", ARG0
save ARG1 . ".gp"
set term push
set term png @ARG2
set output ARG1 . ".png"
replot
unset output
set term pop
I find the entire call mechanism ugly, however. I'd be more likely to do
newplot = 'myplot'
newsize = '160,100'
load 'script.gp'
script.gp:
~~~~~~
save newplot . ".gp"
set term png size @newsize
set output newplot . ".png"
replot
unset output
unset term
~~~~~~
