                       The Graphics Software DISLIN
                    ----------------------------------


Introduction
------------

DISLIN is a high level library of  subroutines and  functions that display
data graphically. It is intended to be a powerful and easy to use software
package for programmers  and scientists that does not require knowledge of
hardware features. The software is available for the programming languages
C, Fortran 77 and Fortran 90.

DISLIN  stores the  graphic information in a  device-independent  metafile
that is converted by a device  driver program for  plotting on various de-
vices. Two formats can be selected: a GKSLIN metafile coded in ASCII and a
CGM binary metafile corresponding to the ANSI norm. Device-dependent plot-
files  can also be  generated by  DISLIN  such as  PostScript files,  HPGL 
files,  Prescribe files for Kyocera printers,  and Tektronix and  X Window
emulations for graphic terminals.

The library contains the following features:

  -  9 software fonts where each font provides 6 alphabets. Hardware fonts
     for PostScript printers can also be used.

  -  Plotting of two- and three-dimensional axis systems.  Axes can be li-
     nearly or  logarithmically scaled and labeled with linear,  logarith-
     mic, time, map and user-defined formats.

  -  Plotting of curves. Several curves can  appear in one axis system and
     can be  differentiated  by colour,  line style and pattern.  Multiple
     axis systems can be displayed on a page.

  -  Plotting of legends.

  -  Elementary  plot routines  for lines,  vectors and outlined or filled
     regions such as rectangles, circles, arcs, ellipses and polygons.

  -  Shielded regions can be defined.

  -  Business graphics.

  -  3-D colour graphics.

  -  3-D graphics.

  -  Elementary image routines.

  -  Geographical projections and plotting of maps.

  -  Contouring.


Manuals in English are available.
