 * This widget displays a grid and traces a graph on it following a set of

 * @deprecated This class is part of the java-gnome 2.x family of libraries,
 *             which, due to their inefficiency and complexity, are no longer
 *             being maintained and have been abandoned by the java-gnome
 *             project. This class may in the future have an equivalent in
 *             java-gnome 4.0, try looking for
 *             <code>org.gnome.gtk.Curve</code>.
 *             You should be aware that there is a considerably different API
 *             in the new library: the architecture is completely different
 *             and most notably internals are no longer exposed to public view.
