Another option is to embed a plotutils widget in your GTK widget.  I
can probably dig up some code if needed.  You can get plotutils from
ftp.gnu.org/pub/gnu.  It's mostly designed for rendering static plots
to screen, postscript, fig, tek, etc., but it has some support for
incremental rendering of incoming data.

Right now, you can't put a full blown graph into an Xdrawable (it has
to come up in a separate window via the "graph" process, but support
for embedded graphs should be coming.  Currently you *can* use its
lower level drawing primitives (that are pretty powerful) to draw to
an arbitrary Xdrawable.
