how to save two plots simultaneously in gnuplot

Hiii...

I havebeen trying to plot two curves simultaneously in a single plot to compare them. ie, by the command:

plot "1.txt" w l, "2.txt" w l

now I want to save it, but the usual command for saving is:

set out "1.txt"

but in this case how can I save them together in a same plot?

For saving a plot as a file on your disk, you need to setup two things: a terminal and an output. Suppose you have configured your plot interactively in a command-line gnuplot session, this is an example:

terminal

output

set terminal png
set output "myplot.png"

replot

unset output


where replot does what its command name suggests, it repeats the last plot command - and if that last plot command showed both curves as you wanted it, they will identically show up in the output file. For info on supported terminal types on your system, read help terminal.

replot

plot

help terminal
