Maybe we can use the glinegraph widget
http://sourceforge.net/project/showfiles.php?group_id=157888&package_id=191712
or use it as a basis to make our own.

"
A Gtk2/GLib2/cario GUI application which demonstrates the use of GTK+ for
 producing xy line graphs.  This widget once created allows you to add one
or more
 data series, then add values to those series for ploting.  The X point is
assumed based
 on arrival order.  However, the Y value or position is based one the
current scale and
 the y value itself.  If the charts x scale maximum is 40, or 40 points, the
41+ value is
 appended to the 40th position after all points are shifted left and out
through pos 0.

 Packaged as a gtk widget for ease of use.

There is a very interesting sample demo in the archive.
