DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
_G_n_u_p_l_o_t is a command-driven interactive function plotting
program.
If files are given, _g_n_u_p_l_o_t loads each file with the _l_o_a_d
command, in the order specified. _G_n_u_p_l_o_t 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, Commodore Amiga, Roland DXY800A,
EEPIC, TeXDraw, EmTeX, Epson 60dpi printers, Epson LX-800,
Fig, HP2623, HP2648, HP75xx, HPGL, HP LaserJet II, Imagen,
Iris 4D, Linux, MS-DOS Kermit, 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.

_G_n_u_p_l_o_t provides the _x_1_1 terminal type for use with X
servers. This terminal type is set automatically at startup
if the DDDDIIIISSSSPPPPLLLLAAAAYYYY environment variable is set, if the TTTTEEEERRRRMMMM
environment variable is set to xxxxtttteeeerrrrmmmm, or if the ----ddddiiiissssppppllllaaaayyyy
command line option is used. For terminal type _x_1_1, _g_n_u_p_l_o_t
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:
----mmmmoooonnnnoooo forces monochrome rendering on color displays.
----ggggrrrraaaayyyy requests grayscale rendering on grayscale or color
displays. (Grayscale displays receive monochrome rendering
by default.)
----cccclllleeeeaaaarrrr requests that the window be cleared momentarily
before a new plot is displayed.
----ttttvvvvttttwwwwmmmm 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
....XXXXddddeeeeffffaaaauuuullllttttssss file. For example: ggggnnnnuuuuppppllllooootttt****ggggrrrraaaayyyy:::: oooonnnn .
_G_n_u_p_l_o_t provides a command line option (----ppppooooiiiinnnnttttssssiiiizzzzeeee _v) and a
resource (ggggnnnnuuuuppppllllooootttt****ppppooooiiiinnnnttttssssiiiizzzzeeee:::: _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,
----ppppooooiiiinnnnttttssssiiiizzzzeeee 2222 uses points twice the default size, and
----ppppooooiiiinnnnttttssssiiiizzzzeeee 0000....5555 uses points half the normal size.
For monochrome displays, _g_n_u_p_l_o_t does not honor foreground
or background colors. The default is black-on-white. ----rrrrvvvv or
ggggnnnnuuuuppppllllooootttt****rrrreeeevvvveeeerrrrsssseeeeVVVViiiiddddeeeeoooo:::: oooonnnn requests white-on-black.
For color displays _g_n_u_p_l_o_t 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 _i_n_t_e_n_s_i_t_y value from 0 to 1.
For example, bbbblllluuuueeee,,,,....5555 means a half intensity blue.

_G_n_u_p_l_o_t 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.

_G_n_u_p_l_o_t honors the following resources for setting the dash
style used for plotting lines. 0 means a solid line. A 2
digit number _j_k (_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
