  16.       _G_n_u_p_l_o_t is a command-driven interactive function plotting
  17.       program.
  18.  
  19.       If files are given, _g_n_u_p_l_o_t loads each file with the _l_o_a_d
  20.       command, in the order    specified.  _G_n_u_p_l_o_t exits after    the
  21.       last file is processed.
  22.  
  23.       Here are some    of its features:
  24.  
  25.       Plots    any number of functions, built up of C operators, C
  26.       library functions, and some things C doesn't have like **,
  27.       sgn(), etc.  Also support for    plotting data files, to
  28.       compare actual data to theoretical curves.
  29.  
  30.       User-defined X and Y ranges (optional    auto-ranging), smart
  31.       axes scaling,    smart tic marks.
  32.  
  33.       Labelling of X and Y axes.
  34.  
  35.       User-defined constants and functions.
  36.  
  37.       Support through a generalized    graphics driver    for AED    512,
  38.       AED 767, BBN BitGraph, Commodore Amiga, Roland DXY800A,
  39.       EEPIC, TeXDraw, EmTeX, Epson 60dpi printers, Epson LX-800,

  41.       Iris 4D, Linux, MS-DOS Kermit, Kyocera laser printer,    LaTeX,
  42.       NEC CP6 pinwriter, PostScript, QMS QUIC, ReGis (VT125    and
  43.       VT2xx), SCO Xenix CGI, Selanar, Star color printer, Tandy

  45.       Tektronix emulator, Unix PC (ATT 3b1 or ATT 7300), unixplot,
  46.       and X11.  The    PC version compiled by Microsoft C supports
  47.       IBM CGA, EGA,    VGA, Hercules, ATT 6300, and Corona 325
  48.       graphics.  The PC version compiled by    Borland    C++ supports
  49.       IBM CGA, EGA,    MCGA, VGA, Hercules and    ATT 6300 graphics.
  50.       Other    devices    can be added simply, but will require
  51.       recompiling.
  52.  
  53.       Shell    escapes    and command line substitution.
  54.  
  55.       Load and save    capability.
  56.  
  57.       Output redirection.
  58.  
  59.       All computations performed in    the complex domain.  Just the
  60.       real part is plotted by default, but functions like imag()

  78.       _G_n_u_p_l_o_t provides the _x_1_1 terminal type for use with X
  79.       servers. This    terminal type is set automatically at startup
  80.       if the DDDDIIIISSSSPPPPLLLLAAAAYYYY environment variable is set, if the TTTTEEEERRRRMMMM
  81.       environment variable is set to xxxxtttteeeerrrrmmmm,    or if the ----ddddiiiissssppppllllaaaayyyy
  82.       command line option is used.    For terminal type _x_1_1, _g_n_u_p_l_o_t
  83.       accepts the standard X Toolkit options and resources such as
  84.       geometry, font, and background. See the X(1) man page    for a
  85.       description of the options.  In addition to the X Toolkit
  86.       options:
  87.  
  88.       ----mmmmoooonnnnoooo    forces monochrome rendering on color displays.
  89.  
  90.       ----ggggrrrraaaayyyy    requests grayscale rendering on    grayscale or color
  91.       displays.  (Grayscale    displays receive monochrome rendering
  92.       by default.)
  93.  
  94.       ----cccclllleeeeaaaarrrr requests that the window be cleared momentarily
  95.       before a new plot is displayed.
  96.  
  97.       ----ttttvvvvttttwwwwmmmm requests that geometry    specifications for position of
  98.       the window be    made relative to the currently displayed
  99.       portion of the virtual root.
  100.  
  101.       These    options    may also be controlled with resources in your
  102.       ....XXXXddddeeeeffffaaaauuuullllttttssss file.  For    example: ggggnnnnuuuuppppllllooootttt****ggggrrrraaaayyyy:::: oooonnnn .
  103.  
  104.       _G_n_u_p_l_o_t provides a command line option (----ppppooooiiiinnnnttttssssiiiizzzzeeee _v)    and a
  105.       resource (ggggnnnnuuuuppppllllooootttt****ppppooooiiiinnnnttttssssiiiizzzzeeee:::: _v) to control the size of
  106.       points plotted with the "points" plotting style. The value _v
  107.       is a real number (greater than 0 and less than or equal to
  108.       ten) used as a scaling factor    for point sizes. For example,
  109.       ----ppppooooiiiinnnnttttssssiiiizzzzeeee 2222 uses points twice the default size, and
  110.       ----ppppooooiiiinnnnttttssssiiiizzzzeeee 0000....5555 uses points half the normal size.
  111.  
  112.       For monochrome displays, _g_n_u_p_l_o_t does    not honor foreground
  113.       or background    colors.    The default is black-on-white. ----rrrrvvvv or
  114.       ggggnnnnuuuuppppllllooootttt****rrrreeeevvvveeeerrrrsssseeeeVVVViiiiddddeeeeoooo::::    oooonnnn requests white-on-black.
  115.  
  116.       For color displays _g_n_u_p_l_o_t honors the    following resources
  117.       (shown here with default values). The    values may be color
  118.       names    in the X11 rgb.txt file    on your    system,    hexadecimal
  119.       RGB color specifications (see    X11 documentation), or a color
  120.       name followed    by a comma and an _i_n_t_e_n_s_i_t_y value from 0 to 1.
  121.       For example, bbbblllluuuueeee,,,,....5555 means a half intensity blue.
