Hello everybody,

I just wrote a plugin for TeXgraph. This software makes it possible to 
create graphs which will be used inside LaTeX (you can find this really 
good software in French at http://texgraph.tuxfamily.org/index.html).
I followed the help files to create two files :
- tm_texgraph based on tm_pstricks by Nicolas Ratier
- init-texgraph.scm based on init-eukleides.scm by Joris van der Hoeven.
To use it, you have to extract texgraph.tar.gz in the 
"~/.TeXmacs/plugin" directory under linux and to install TeXgraph of course.

As it is my first attempt to do something like this, it is not clean and 
seems buggy.
There are a few things I can't correct. For example, in the following 
TeXgraph session in TeXmacs, I can't remove the red <\errput> just below 
the graph.

<\output>
 <with|mode|math|T<rsub|E>X*g*r*a*p*h>
 TeXmacs interface to TeXgraph.
 Defaut : Fenetre(-4+3*i,4-3*i,1+i), Marges(0.25,0.25,0.25,0.25)
</output>

So your comments would be very welcome.
And as it is my first post on this forum, thank you for this great 
software that I discovered 2 years ago.


Bye.

the input and sends it to TeXgraph.
