Synopsis
gnuplot [options
] [files
]
The gnuplot
program creates
graphs, plotting points and connecting them with lines and curves,
and saves them in a wide variety of printer and plotter formats,
such as PostScript. To use gnuplot
, you need to learn a small but
powerful programming language. Here’s an example of plotting the
curve y =
x
2 from x
= 1 to 10, which will appear in an X
window on your display:
$ gnuplot gnuplot>plot [1:10] x**2
gnuplot>quit
To do the same, saving the results as a PostScript file:
$ cat myfile set terminal postscript plot [1:10] x**2 $ gnuplot < myfile > output.ps
