Purpose: to discuss what '''plplot''' means .
----
The name "plplot" appears to be associated with several items - I'm uncertain
at this time whether these are all derivatives of one another or all different.

Items 1,2,3 are effectively identical (now that the source trees have been merged, finally) -- the old 'dino.ph.utexas.edu' items are probably obsolete and/or may not work.  Item 4 is an application which ''uses'' plplot (and there are many, many applications in that category, including 'R').

People should feel free to add info about other applications that make use of plplot -the idea is to help people learn how they can leverage tools to greater productivity.

 Description: Plplot is a GLPL'ed graphing and plotting package, containing
        much improved C++ and Tk (and incr Tk) integration compared to
        the old releases.  It also
        includes a stand alone Tcl matrix object.
        Binary versions of MacOS 8.1 and Windows NT are also available.
        Currently at version 5.1.0 .

 Where: ftp://dino.ph.utexas.edu/plplot/distrib/plplot4p99i.tar.gz
        http://www.fas.harvard.edu/%7Edarley/pLTK.html
 Description: A scientific plotting package, containing a wide range of
        plot types and font characters.  It supports many different
        output device drivers.  The X driver is written in Tk.  It
        provides a full user interface, with zoom, pan, orient, etc.
        There is a Tk plotting widget as well.  The Plplot Tk widget has
        also been ported to work on Macintosh.
        Now requires Tcl/Tk 8.x.
        There is a plplot mailing list mentioned in the docs.
        Plplot uses the GNU licensing.

 Description: TiM is a Tcl extension designed to process 2 dimensional
        arrays of binary data (referred to as a matrix).  Think of it is
        a MatLab-like Tcl extension.  Provies arithmetic operations on
        matrices, transformations, various data types, ability to read and
        write binary data in little or big endian byte order, ability
        to write image file formats with or without automatic compression,
        plot drawing (with PLplot), and various other image manipulation
        procedures.

Plplot is on sourceforge: http://sourceforge.net/project/showfiles.php?group_id=2915

PLplot is relatively small, portable, freely distributable, and is rich
enough to satisfy most users.  It has a wide range of plot types including
line (linear, log), contour, 3D, fill, and almost 1000 characters
(including Greek and mathematical) in its extended font set.  The package
is designed to make it easy to quickly get graphical output; only a
handful of function calls is typically required.  For more advanced use,
virtually all aspects of plotting are configurable.

Both ordinary tk widgets and some embedded widgets (which require Itcl) are provided.

A binary compile of an extension for WinTk is available here: 
ftp://ftp.ucsd.edu/pub/alpha/tcl/extensions/plplot5.1a.zip
Also see http://www.santafe.edu/~vince/Pltk.html for some screenshots.

[http://www.santafe.edu/~vince/pics/plDemo1.gif]

The cvs distribution contains many examples (in examples/tcl and examples/tk) which work well with this binary release.

Plplot now reroutes all file i/o to Tcl (if desired) and therefore can make use of vfs support and so will work from inside a scripted document (it contains a number of support files for drawing numerous glyphs and world maps which it wants to load).

[Vince] was responsible for making Plplot work with Tk cross-platform.
