* Changes
* -------
* 19-Oct-2001 : Version 1, based on code by Mark Watson (DG);
* 22-Oct-2001 : Renamed DataSource.java --> Dataset.java etc. (DG);
* 13-Dec-2001 : Changed return type of drawItem from void --> Shape. The area
* returned can be used as the tooltip region.
* 23-Jan-2002 : Added DrawInfo parameter to drawItem() method (DG);
* 28-Mar-2002 : Added a property change listener mechanism. Now renderers do
* not have to be immutable (DG);
* 04-Apr-2002 : Added the initialise() method (DG);
* 09-Apr-2002 : Removed the translated zero from the drawItem method, it can
* be calculated inside the initialise method if it is required.
* Added a new getToolTipGenerator() method. Changed the return
* type for drawItem() to void (DG);
* 24-May-2002 : Added ChartRenderingInfo the initialise method API (DG);
* 25-Jun-2002 : Removed redundant import (DG);
* 20-Aug-2002 : Added get/setURLGenerator methods to interface (DG);
* 02-Oct-2002 : Fixed errors reported by Checkstyle (DG);
* 18-Nov-2002 : Added methods for drawing grid lines (DG);
* 17-Jan-2003 : Moved plot classes into a separate package (DG);
* 27-Jan-2003 : Added shape lookup table (DG);
* 05-Jun-2003 : Added domain and range grid bands (sponsored by Focus Computer
* Services Ltd) (DG);
* 27-Jul-2003 : Added getRangeType() to support stacked XY area charts (RA);
* 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG);
* 25-Feb-2004 : Replaced CrosshairInfo with CrosshairState. Renamed
* XYToolTipGenerator --> XYItemLabelGenerator (DG);
* 26-Feb-2004 : Added lots of new methods (DG);
* 30-Apr-2004 : Added getRangeExtent() method (DG);
* 06-May-2004 : Added methods for controlling item label visibility (DG);
* 13-May-2004 : Removed property change listener mechanism (DG);
* 18-May-2004 : Added item label font and paint methods (DG);
* 10-Sep-2004 : Removed redundant getRangeType() method (DG);
* 06-Oct-2004 : Replaced getRangeExtent() with findRangeBounds() and added
* findDomainBounds (DG);
* 23-Nov-2004 : Changed drawRangeGridLine() --> drawRangeLine() (DG);
* 07-Jan-2005 : Removed deprecated method (DG);
* 24-Feb-2005 : Now extends LegendItemSource (DG);
* 20-Apr-2005 : Renamed XYLabelGenerator --> XYItemLabelGenerator (DG);
* ------------- JFREECHART 1.0.x ---------------------------------------------
* 19-Apr-2007 : Deprecated seriesVisible and seriesVisibleInLegend flags (DG);
* 20-Apr-2007 : Deprecated paint, fillPaint, outlinePaint, stroke,
* outlineStroke, shape, itemLabelsVisible, itemLabelFont,
* itemLabelPaint, positiveItemLabelPosition,
* negativeItemLabelPosition and createEntities override
* fields (DG);
