NAME

gnuplot - an interactive plotting program

SYNOPSIS

gnuplot [ X11 options ] [file ...]

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.

Here are some of its features:

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.

User-defined X and Y ranges (optional auto-ranging), smart axes scaling, smart tic marks.

Labelling of X and Y axes.

User-defined constants and functions.

Support through a generalized graphics driver for AED 512, AED 767, BBN BitGraph, Roland DXY800A, EEPIC, EmTeX, Epson 60dpi printers, Epson LX-800, Fig, HP2623, HP2648, HP75xx, HPGL, HP LaserJet II, Imagen, Iris 4D, Kermit-MS, Kyocera laser printer, LaTeX, NEC CP6 pinwriter, PostScript, QMS QUIC, ReGis (VT125 and VT2xx), SCO Xenix CGI, Selanar, Star color printer, Tandy DMP-130 printer, Tek 401x, Tek 410x, Vectrix 384, VT like tekronix emulator, Unix PC (ATT 3b1 or ATT 7300), unixplot, and X11. 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.

Shell escapes and command line substitution.

Load and save capability.

Output redirection.

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.

X11 OPTIONS

Gnuplot provides two terminal types (x11 and X11) for use with X servers. The X11 terminal type provides differing colors as well as shapes for the points plotting style. The two types are otherwise identical. When used with either of these terminal types, gnuplot 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 gnuplot also honors the following resources (shown here with default values):

gnuplot*textColor: black
gnuplot*borderColor: black
gnuplot*axisColor: black
gnuplot*line1Color: red
gnuplot*line2Color: green
gnuplot*line3Color: blue
gnuplot*line4Color: magenta
gnuplot*line5Color: cyan
gnuplot*line6Color: sienna
gnuplot*line7Color: orange
gnuplot*line8Color: coral

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