gnuplot
tem um comando set output
que eu uso para salvar uma cópia do meu gráfico:
#!/bin/bash
# Run this script after synching the Palm with $HOME/Visor/.last
# Weight - extract my weight data fron the Visor, clean it
# up, and feed it to gnuplot
target=$HOME/Visor/var/Weight
visorhome="$HOME/Visor"
gnuplotdata="${target}.pltdata"
gnuplotout="${target}.ps"
# ... data prep omitted - data to plot is in $gnuplotdata
gnuplot <<EOF
set title "Weight and running average, in kilograms, for Walt Sullivan"
set timefmt "%y/%m/%d"
set xdata time
set format x "%y/%m/%d"
plot "$gnuplotdata" using 1:2 with linespoints, "" using 1:3 with linespoints;
pause 10 "Plot will close in 10 seconds, see $gnuplotout"
set terminal postscript enhanced color landscape
set output "$gnuplotout"
replot
EOF
exit 0

$ gnuplot
gnuplot> help set output
By default, screens are displayed to the standard output. The 'set output'
command redirects the display to the specified file or device.
