Added new constructor. (DG); * 16-Jan-2002 : Renamed the tooltips class (DG); * 22-Jan-2002 : Added DrawInfo class, incorporating tooltips and crosshairs. * Crosshairs based on code by Jonathan Nash (DG); * 05-Feb-2002 : Added alpha-transparency setting based on code by Sylvain * Vieujot (DG); * 26-Feb-2002 : Updated getMinimumXXX() and getMaximumXXX() methods to handle * special case when chart is null (DG); * 28-Feb-2002 : Renamed Datasets.java --> DatasetUtilities.java (DG); * 28-Mar-2002 : The plot now registers with the renderer as a property change * listener.
