It partitions the canvas to contain thespecified axes with the remaining space taken with the plotting region.Axes are packed against the walls of the canvas. The <B>paint</B> and<B>update</B> methods of this class handle all the drawing operations of thegraph. This means that independent components like Axis and DataSets must beregistered with this class to be incorporated into the plot.<dl> <dt> <b>Version:</b> <dd> 1.12, 1996/09/24 05:23:41 <dt>
