       gnuplot - an interactive plotting program

       gnuplot [ X11 options ] [file ...]

       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,  Com-
       modore  Amiga,  Roland DXY800A, EEPIC, TeXDraw, EmTeX, Epson 60dpi printers, Epson LX-800,

       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 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 graphics.  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.

       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 environ-
       ment variable is set to xterm, or if the -display command line option is used.  For termi-
       nal  type x11, gnuplot accepts the standard X Toolkit options and resources such as geome-
       try, 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 program 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 portion 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 val-
       ues). 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 dis-
       plays (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 example, '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 resizing the gnuplot window.

       The atan() function does not work correctly for complex arguments.
       The bessel functions do not work for complex arguments.
