 *

 * 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);

 *

 * DO NOT USE drawHorizontalItem() - IT IS INCOMPLETE

 * TO EXPERIMENT, USE drawVerticalItem()

 *
