[romildo]

Hello.

I am looking for an ocaml plot library that integrates
well with lablgtk. Is there one?

If not, how are graphics plotted in OCaml and lablgtk?

I am accepting sugestions.

I've used the Gnome Canvas widget in lablgtk2 with much success.  It's
included with lablgtk2 in "lablgnomecanvas.cma".  It's based on Tk's
canvas widget but is much more powerful.  Unfortunately it's not
available for lablgtk, only lablgtk2.  You can find docs for it at
http://compiler.kaist.ac.kr/~shoh/ocaml/lablgtk2/lablgtk-2.4.0/doc/html/GnoCanvas.html.

Does it work in Windows too?

And can you print it?

It doesn't seem to be included in the Win32 distribution of LablGTK2,
but if you're using Cygwin then I presume it will compile given the
right libraries.

No.  This is one area in which the Gnome Canvas is actually inferior
to the Tk canvas widget.

I have some code which allows you to print the Gtk drawing area under
Windows.  It's very hacky - basically it is possible to get a bitmap
of the drawing area, which is then written out as a PPM file, which is
then piped into a separate "winprint" program which I derived from the
guts of the GIMP printer driver for Windows.  Anyway, let me know if
you want it.

I'd like to see it.  Perhaps it's something for the humps?

We do all of our graphics using OpenGL (via the excellent lablgl).
