.SH NAME
gnuplot \- an interactive plotting program
.SH SYNOPSIS
.B gnuplot
[ X11 options ] [file ...]
.br
.SH DESCRIPTION
.I Gnuplot
is a command-driven interactive function plotting program.
.PP
If files are given,
.I gnuplot
loads each file with the
.I load
command, in the order specified.
.I Gnuplot
exits after the last file is processed.
.PP
Here are some of its features:
.PP
Plots any number of functions, built up of C operators, C library
functions, and some things C doesn't have like **, sgn(), etc. Also
support for plotting data files, to compare actual
data to theoretical curves.
.PP
User-defined X and Y ranges (optional auto-ranging), smart axes scaling,
smart tic marks.
.PP
Labelling of X and Y axes.
.PP
User-defined constants and functions.
.PP
Support through a generalized graphics driver for

The PC version compiled by Microsoft C
supports IBM CGA, EGA, VGA, Hercules, ATT 6300,
and Corona 325 graphics.
The PC version compiled by Turbo C
supports IBM CGA, EGA, MCGA, VGA, Hercules and ATT 6300 graphics.
Other devices can be added simply, but will require recompiling.
.PP
Shell escapes and command line substitution.
.PP
Load and save capability.
.PP
Output redirection.
.PP
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.
.SH X11 OPTIONS
.I Gnuplot
provides two terminal types (\fIx11\fP and \fIX11\fP) for use
with X servers. The \fIX11\fP terminal type provides differing colors as well
as shapes for the \fIpoints\fP plotting style. The two types are otherwise
identical. When used with either of these terminal types, \fIgnuplot\fP
honors all the standard X Toolkit options and resources such as geometry, font,
foreground and background. See the X(1) man page for a description of
the options. For color or grayscale displays \fIgnuplot\fP also honors
the following resources (shown here with default values):
.sp
.B "gnuplot*textColor: black"
.br
.B "gnuplot*borderColor: black"
.br
.B "gnuplot*axisColor: black"
.br
.B "gnuplot*line1Color: red"
.br
.B "gnuplot*line2Color: green"
.br
.B "gnuplot*line3Color: blue"
.br
.B "gnuplot*line4Color: magenta"

.B "gnuplot*line6Color: sienna"
.br
.B "gnuplot*line7Color: orange"
.br
.B "gnuplot*line8Color: coral"

.PP
The size or aspect ratio of a plot may be changed by resizing the
.I gnuplot
window.
