* (C) Copyright 2003-2009, by David Browning and Contributors.
*
* Original Author: David Browning (for Australian Institute of Marine
* Science);
* Contributor(s): David Gilbert (for Object Refinery Limited);
*
* Changes
* -------
* 05-Aug-2003 : Version 1, contributed by David Browning. Based on code in the
* CandlestickRenderer class. Additional modifications by David
* Gilbert to make the code work with 0.9.10 changes (DG);
* 08-Aug-2003 : Updated some of the Javadoc
* Allowed BoxAndwhiskerDataset Average value to be null - the
* average value is an AIMS requirement
* Allow the outlier and farout coefficients to be set - though
* at the moment this only affects the calculation of farouts.
* Added artifactPaint variable and setter/getter
* 12-Aug-2003 Rewrote code to sort out and process outliers to take
* advantage of changes in DefaultBoxAndWhiskerDataset
* Added a limit of 10% for width of box should no width be
* specified...maybe this should be setable???
* 20-Aug-2003 : Implemented Cloneable and PublicCloneable (DG);
* 08-Sep-2003 : Changed ValueAxis API (DG);
* 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG);
* 25-Feb-2004 : Replaced CrosshairInfo with CrosshairState (DG);
* 23-Apr-2004 : Added fillBox attribute, extended equals() method and fixed
* serialization issue (DG);
* 29-Apr-2004 : Fixed problem with drawing upper and lower shadows - bug id
* 944011 (DG);
* 15-Jul-2004 : Switched getX() with getXValue() and getY() with
* getYValue() (DG);
* 01-Oct-2004 : Renamed 'paint' --> 'boxPaint' to avoid conflict with
* inherited attribute (DG);
* 10-Jun-2005 : Updated equals() to handle GradientPaint (DG);
* 06-Oct-2005 : Removed setPaint() call in drawItem(), it is causing a
* loop (DG);
* ------------- JFREECHART 1.0.x ---------------------------------------------
* 02-Feb-2007 : Removed author tags from all over JFreeChart sources (DG);
* 05-Feb-2007 : Added event notifications and fixed drawing for horizontal
* plot orientation (DG);
* 13-Jun-2007 : Replaced deprecated method call (DG);
* 03-Jan-2008 : Check visibility of average marker before drawing it (DG);
* 27-Mar-2008 : If boxPaint is null, revert to itemPaint (DG);
* 27-Mar-2009 : Added findRangeBounds() method override (DG);
*
