 *
 * Changes
 * -------
 * 11-Apr-2002 : Version 1, contributed by Bryan Scott;
 * 15-Apr-2002 : Changed to implement VerticalValuePlot;
 * 29-Apr-2002 : Added getVerticalValueAxis() method (DG);
 * 25-Jun-2002 : Removed redundant imports (DG);
 * 17-Sep-2002 : Reviewed with Checkstyle utility (DG);
 * 18-Sep-2002 : Extensive changes made to API, to iron out bugs and
 *               inconsistencies (DG);
 * 13-Oct-2002 : Corrected error datasetChanged which would generate exceptions
 *               when value set to null (BRS).
 * 23-Jan-2003 : Removed one constructor (DG);
 * 26-Mar-2003 : Implemented Serializable (DG);
 * 02-Jun-2003 : Removed test for compatible range axis (DG);
 * 01-Jul-2003 : Added additional check in draw method to ensure value not
 *               null (BRS);
 * 08-Sep-2003 : Added internationalization via use of properties
 *               resourceBundle (RFE 690236) (AL);
 * 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG);
 * 29-Sep-2003 : Updated draw to set value of cursor to non-zero and allow
 *               painting of axis.  An incomplete fix and needs to be set for
 *               left or right drawing (BRS);
 * 19-Nov-2003 : Added support for value labels to be displayed left of the
 *               thermometer
 * 19-Nov-2003 : Improved axis drawing (now default axis does not draw axis line
 *               and is closer to the bulb).  Added support for the positioning
 *               of the axis to the left or right of the bulb. (BRS);
 * 03-Dec-2003 : Directly mapped deprecated setData()/getData() method to
 *               get/setDataset() (TM);
 * 21-Jan-2004 : Update for renamed method in ValueAxis (DG);
 * 07-Apr-2004 : Changed string width calculation (DG);
 * 12-Nov-2004 : Implemented the new Zoomable interface (DG);
 * 06-Jan-2004 : Added getOrientation() method (DG);
 * 11-Jan-2005 : Removed deprecated code in preparation for 1.0.0 release (DG);
 * 29-Mar-2005 : Fixed equals() method (DG);
 * 05-May-2005 : Updated draw() method parameters (DG);
 * 09-Jun-2005 : Fixed more bugs in equals() method (DG);
 * 10-Jun-2005 : Fixed minor bug in setDisplayRange() method (DG);
 * ------------- JFREECHART 1.0.x ---------------------------------------------
 * 14-Nov-2006 : Fixed margin when drawing (DG);
 * 03-May-2007 : Fixed datasetChanged() to handle null dataset, added null
 *               argument check and event notification to setRangeAxis(),
 *               added null argument check to setPadding(), setValueFont(),
 *               setValuePaint(), setValueFormat() and setMercuryPaint(),
 *               deprecated get/setShowValueLines(), deprecated
 *               getMinimum/MaximumVerticalDataValue(), and fixed serialization
 *               bug (DG);
 * 24-Sep-2007 : Implemented new methods in Zoomable interface (DG);
 * 08-Oct-2007 : Added attributes for thermometer dimensions - see patch 1769088
 *               by Julien Henry (DG);
