SOME NOTES ON GNUPLOT ON THE AMIGA ...



Environment Variables:

   GNUHELP   Allows you to define a pathname for the gnuplot help file.  For
             example, "setenv GNUHELP TEX:gnuplot.gih"

   GNUPLOT   Your current directory is searched for the file ".gnuplot".
             If you say "setenv GNUPLOT <Path>" (without the filename!)
             gnuplot will look for it there.

   GNUTERM   You can define a default driver with "setenv GNUTERM <driver>".
             A good choice is "setenv GNUTERM amiga" :^)

   SHELL     If you don't like "NewShell" as your shell, you can say
             "setenv SHELL <Shell>".


Stack Size:

   A stack size of at least 25000 bytes should be used while running gnuplot.
   If you use recursive functions, e.g. like in "bivariat.dem", you will have
   to increase your stack size accordingly. Otherwise gnuplot will exit with
   a run time error.


Pipes:

  As of version 3.6 gnuplot supports the use of pipes for the input of data
  in the same manner as under Unix. See the appropriate part of the manual
  for further details. This feature is only available if Kickstart 2.0 or
  higher is installed on your Amiga.

  To execute the examples given in the docs, you will have to use the port
  of AT&T awk that is available on aminet-sites as ATT-awk-1_0.lha. Don't
  use the port of gawk that has been uploaded to aminet because it is
  severely broken. None of the examples will work with that version of awk.

  The Amiga version now supports output of the online documentation through
  external pagers. This feature is enabled if you set the environment
  variable PAGER to a reasonable value. The pager used must be able to take
  its input from stdin. Older versions of more supplied with Commodore's
  workbench don't allow this and won't work. I recommend the use of
  Less 1.6Z (available on aminet). Set your environment variable PAGER to
  "less -[cli]" or set the variable LESS to "-[cli]" and PAGER to "less".



--------------------------   SAS/C 6.1 VERSION   -----------------------------


Default paths/directories:

   Gnuplot looks for the file "gnuplot.gih" in your "S:"-directory unless you
   specify the full pathname including the filename via "setenv GNUHELP".




---------------------------   AZTEC C VERSION   ------------------------------

Default paths/directories:

   Gnuplot looks for the "gnuplot.gih" file in "GNUPLOT:docs/gnuplot.gih" if
   GNUHELP is not defined.   This is defined in the makefile (makefile.ami).


Terminal Drivers:

   The Aztec C version can now use the "amiga.trm" driver written by
   Carsten Steger.  Under KS/WB 2.0, a custom screen will be used with a size
   specified by the Prefs/Overscan program.
