GNUPLOT(1) General Commands Manual GNUPLOT(1)
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, gnu-
plot 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 de-
fault, 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, er-
ror 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 op-
tions. 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 re-
quired.
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 termi-
nal" 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 li-
brary.
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" vari-
able, 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 cus-
tom 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 pri-
vate 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.
