## Software Description

Gnuplot is a command-driven interactive function plotting program. If
files are given, gnuplot loads each file with the load command, in the
order specified. gnuplot exits after the last file is processed. It
plots any number of functions, built up of C operators, C library
functions, and some things C doesn\'t have, such as \*\*, sgn(), etc. It
also provides support for plotting data files, to compare actual data to
theoretical curves, user-defined X and Y ranges (optional auto-ranging),
smart axes scaling, and smart tick marks.
## General Linux

To run this software interactively in a Linux environment run the command:

	gnuplot

To run gnuplot on a script that produces an output file and no immediate display, type

	gnuplot myscript.plt

To run gnuplot on a script that immediately displays a plot, type

	gnuplot -persist myscript.plt

Note, if you want to run gnuplot remotely, use X-forwarding to get plots displayed at your terminal. For example, from your local linux host you would start by logging into an MSI host (such as login) with

	ssh -X username@login.msi.umn.edu

For more information, see the gnuplot man page

	man gnuplot
