NAME
       gnuplot - an interactive plotting program

SYNOPSIS
       gnuplot [X11 options] [options] [file ...]

DESCRIPTION
       Gnuplot is a command-driven interactive plotting program.

       If file names are given on the command line, gnuplot loads and executes
       each file in the order specified, and exits after the last file is
       processed.  If no files are given, gnuplot prompts for interactive
       commands.

       Here are some of its features:

       Plots any number of functions, built up of C operators, C math library
       functions, and some things C doesn't have like **, sgn(), etc.

       User-defined constants and functions.

       All computations performed in the complex domain.  Just the real part
       is plotted by default, but functions like imag() and abs() and arg()
       are available to override this.

       Many presentation styles for plotting user data from files, including
       surface-fitting, error bars, boxplots, histograms, heat maps, and
       simple manipulation of image data.  There is an on-line demo collection
       at
       http://gnuplot.info/demo

       Nonlinear least-squares fitting.

       2D and 3D plots with mouse-controlled zooming, rotation, and hypertext.

       Shell escapes and command line substitution.

       Load and save capability.

       Support for a huge variety of output devices and file formats.

OPTIONS
       -p, --persist lets plot windows survive after main gnuplot program
       exits.

       -c scriptname ARG1 ARG2 ..., load script using gnuplot's "call"
       mechanism and pass it the remainder of the command line as arguments

       -d, --default settings.  Do not read from gnuplotrc or ~/.gnuplot on
       entry.

       -e "command list" executes the requested commands before loading the
       next input file.

       -s, --slow wait for slow font initialization rather than continuing
       with an error.

       -h, --help print summary of usage

       -V show current version

X11 OPTIONS
       For terminal type x11, gnuplot accepts the standard X Toolkit options
       and resources such as geometry, font, and background. See the X(1) man
       page for a description of common options.  For additional X options
       specific to gnuplot, type help x11 on the gnuplot command line. These
       options have no effect on other terminal types.

ENVIRONMENT
       A number of shell environment variables are understood by gnuplot.
       None of these are required.

       GNUTERM
              The name of the terminal type to be used by default.  This can
              be overridden by the gnuplotrc or .gnuplot start-up files and,
              of course, by later explicit "set terminal" commands.

       GNUHELP
              The pathname of the HELP file (gnuplot.gih).

       HOME   The name of a directory to search for a .gnuplot file.

       PAGER  An output filter for help messages.

       SHELL  The program used for the "shell" command.

       FIT_SCRIPT
              Specifies a gnuplot command to be executed when a fit is
              interrupted---see "help fit".

       FIT_LOG
              The name of the logfile maintained by fit.

       GNUPLOT_LIB
              Additional search directories for data and command files. The
              variable may contain a single directory name, or a list of
              directories separated by ':'. The contents of GNUPLOT_LIB are
              appended to the "loadpath" variable, but not saved with the
              "save" and "save set" commands.

       GDFONTPATH
              Several gnuplot terminal drivers access TrueType fonts via the
              gd library.  This variable gives the font search path for these
              drivers.

       GNUPLOT_DEFAULT_GDFONT
              The default font for the terminal drivers that access TrueType
              fonts via the gd library.

       GNUPLOT_FONTPATH
              The font search path used by the postscript terminal. The format
              is the same as for GNUPLOT_LIB. The contents of GNUPLOT_FONTPATH
              are appended to the "fontpath" variable, but not saved with the
              "save" and "save set" commands.

       GNUPLOT_PS_DIR
              Used by the postscript driver to locate external prologue files.
              Depending on the build process, gnuplot contains either a
              builtin copy of those files or simply a default hardcoded path.
              Use this variable to test the postscript terminal with custom
              prologue files. See "help postscript prologue".

FILES
       gnuplotrc
              When gnuplot is run, it first looks for a system-wide
              initialization file named gnuplotrc.  The standard location of
              this file expected by the program is reported by the "show
              loadpath" command.

       .gnuplot
              After loading the system-wide initialization file, if any,
              Gnuplot looks for a private initialization file in the HOME
              directory.  It may contain any legal gnuplot commands, but
              typically they are limited to setting the preferred terminal and
              line types and defining frequently-used functions or variables.

       fit.log
              The default name of the logfile output by the "fit" command.
