gnuplot in mkiv

[Martin 'golodhrim' Scholz]

Hi List,

is a direct usage of gnuplot in ConTeXt MKIV possible or does one need to 
invoke ConTeXt with a special parameter to create a dvi/ps file and 
convert it to pdf? if so an option of generating the graph and converting 
it to be included would be nice in that function, so that a direct usage 
in ConTeXt MKIV would be possible...

Greetings

Martin 'golodhrim' Scholz

Yes.

Example:

\usemodule[gnuplot]
\setupGNUPLOT[terminal=png]
\startGNUPLOTscript[sin]
    plot sin(x)
\stopGNUPLOTscript
\starttext
\useGNUPLOTgraphic[sin]
\stoptext

Cheers, Peter

The context terminal should also work (that is: you may leave out the
"\setupGNUPLOT[terminal=png]" or replace png with context that's
default anyway), but you need some special effort to compile the
terminal:

git clone git://github.com/mojca/gnuplot.git
./prepare
./configure
make

If you would like to keep using that, you can do yourself and others
the favor and write a request to gnuplot-beta@lists.sourceforge.net to
include the terminal in gnuplot's CVS (they say that not enough people
have tested and/or requested its inclusion).

An alternative is to use the lua-tikz terminal. Peter has an
almost-working version that should produce almost-valid (not yet
optimized and maybe not completely future-proof yet) ConTeXt output,
but is not included in official gnuplot version yet (and also the
gnuplot module in ConTeXt needs to be polished a bit in that respect).
Using tikz is not ready yet, but is doable if you have some patience.

You may use [just-in-time or precompiled] PDF/PS/PNG terminals of
course, but you won't be able to add TeX labels and use native
document fonts.

Mojca
