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  com-
     pare 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,  Commodore  Amiga, Roland DXY800A,
     EEPIC, TeXDraw, EmTeX, Epson 60dpi printers,  Epson  LX-800,

     NEC  CP6  pinwriter,  PostScript, QMS QUIC, ReGis (VT125 and

     Tektronix 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 graph-
     ics.   The  PC  version compiled by Borland 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 the  x11  terminal  type  for  use  with  X
     servers.  This terminal type is set automatically at startup
     if the DISPLAY environment variable  is  set,  if  the  TERM
     environment  variable  is  set  to xterm, or if the -display
     command line option is used.  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  the  options.  In addition to the X Toolkit
     options:

     -clear requests  that  the  window  be  cleared  momentarily
     before a new plot is displayed.

     -gray requests grayscale rendering  on  grayscale  or  color
     displays.   (Grayscale displays receive monochrome rendering
     by default.)

     -mono forces monochrome rendering on color displays.

     -persist lets plot windows survive after main  gnuplot  pro-
     gram exits.

     -raise raises the plot window after each plot.

     -noraise does not raise the plot window after each plot.

     -tvtwm requests that geometry specifications for position of
     the  window be made relative to the currently displayed por-
     tion of the virtual root.

     These options may also be controlled with resources in  your
     .Xdefaults file.  For example: gnuplot*gray: on .

     Gnuplot provides a command line option (-pointsize v) and  a
     resource  (gnuplot*pointsize:  v)  to  control  the  size of
     points plotted with the "points" plotting style. The value v
     is  a  real number (greater than 0 and less than or equal to
     ten) used as a scaling factor for point sizes. For  example,
     -pointsize  2  uses  points  twice  the  default  size,  and
     -pointsize 0.5 uses points half the normal size.

     For monochrome displays, gnuplot does not  honor  foreground
     or  background colors. The default is black-on-white. -rv or
     gnuplot*reverseVideo: on requests white-on-black.

     For color displays gnuplot honors  the  following  resources
     (shown  here  with  default values). The values may be color
     names in the X11 rgb.txt file on  your  system,  hexadecimal
     RGB color specifications (see X11 documentation), or a color
     name followed by a comma and an intensity value from 0 to 1.
     For example, blue,.5 means a half intensity blue.
     gnuplot*background: white
     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

     When  -gray  is  selected,  gnuplot  honors  the   following
     resources  for  grayscale or color displays (shown here with
     default values). Note that the default background is black.

     gnuplot*background: black
     gnuplot*textGray: white
     gnuplot*borderGray: gray50
     gnuplot*axisGray: gray50
     gnuplot*line1Gray: gray100
     gnuplot*line2Gray: gray60
     gnuplot*line3Gray: gray80
     gnuplot*line4Gray: gray40
     gnuplot*line5Gray: gray90
     gnuplot*line6Gray: gray50
     gnuplot*line7Gray: gray70
     gnuplot*line8Gray: gray30

     Gnuplot honors the following resources for setting the width
     in  pixels of plot lines (shown here with default values.) 0
     or 1 means a minimal width line of 1 pixel width. A value of
     2 or 3 may improve the  appearance of some plots.

     gnuplot*borderWidth: 2
     gnuplot*axisWidth: 0
     gnuplot*line1Width: 0
     gnuplot*line2Width: 0
     gnuplot*line3Width: 0
     gnuplot*line4Width: 0
     gnuplot*line5Width: 0
     gnuplot*line6Width: 0
     gnuplot*line7Width: 0
     gnuplot*line8Width: 0

     Gnuplot honors the following resources for setting the  dash
     style  used  for  plotting lines.  0 means a solid line. A 2
     digit number jk (j and k are >= 1  and <= 9) means a  dashed
     line  with  a  repeated pattern of j pixels on followed by k
     pixels off.  For example, '16' is a  "dotted"  line  with  1
     pixel  on  followed  by 6 pixels off.  More elaborate on/off
     patterns can be specified with a 4 digit value.   For  exam-
     ple,  '4441' is 4 on, 4 off, 4 on, 1 off. The default values
     shown  below  are  for  monochrome  displays  or  monochrome
     rendering   on   color  or  grayscale  displays.  For  color
     displays, the defaults for all are 0 (solid line) except for
     axisDashes which defaults to a '16' dotted line.

     gnuplot*borderDashes: 0
     gnuplot*axisDashes: 16
     gnuplot*line1Dashes: 0
     gnuplot*line2Dashes: 42
     gnuplot*line3Dashes: 13
     gnuplot*line4Dashes: 44
     gnuplot*line5Dashes: 15
     gnuplot*line6Dashes: 4441
     gnuplot*line7Dashes: 42
     gnuplot*line8Dashes: 13

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

BUGS
     The atan() function does  not  work  correctly  for  complex
     arguments.
