* Original Author: David Gilbert (for Object Refinery Limited);
* Contributor(s): -;
*
* Changes
* -------
* 11-Oct-2001 : Version 1 (DG);
* 18-Oct-2001 : Added implementation of IntervalXYDataSource so that bar plots
* (using numerical axes) can be plotted from time series
* data (DG);
* 22-Oct-2001 : Renamed DataSource.java --> Dataset.java etc. (DG);
* 15-Nov-2001 : Added getSeries() method. Changed name from TimeSeriesDataset
* to TimeSeriesCollection (DG);
* 07-Dec-2001 : TimeSeries --> BasicTimeSeries (DG);
* 01-Mar-2002 : Added a time zone offset attribute, to enable fast calculation
* of the time period start and end values (DG);
* 29-Mar-2002 : The collection now registers itself with all the time series
* objects as a SeriesChangeListener. Removed redundant
* calculateZoneOffset method (DG);
* 06-Jun-2002 : Added a setting to control whether the x-value supplied in the
* getXValue() method comes from the START, MIDDLE, or END of the
* time period. This is a workaround for JFreeChart, where the
* current date axis always labels the start of a time
* period (DG);
* 24-Jun-2002 : Removed unnecessary import (DG);
* 24-Aug-2002 : Implemented DomainInfo interface, and added the
* DomainIsPointsInTime flag (DG);
* 07-Oct-2002 : Fixed errors reported by Checkstyle (DG);
* 16-Oct-2002 : Added remove methods (DG);
* 10-Jan-2003 : Changed method names in RegularTimePeriod class (DG);
* 13-Mar-2003 : Moved to com.jrefinery.data.time package and implemented
* Serializable (DG);
* 04-Sep-2003 : Added getSeries(String) method (DG);
* 15-Sep-2003 : Added a removeAllSeries() method to match
* XYSeriesCollection (DG);
* 05-May-2004 : Now extends AbstractIntervalXYDataset (DG);
* 15-Jul-2004 : Switched getX() with getXValue() and getY() with
* getYValue() (DG);
* 06-Oct-2004 : Updated for changed in DomainInfo interface (DG);
* 11-Jan-2005 : Removed deprecated code in preparation for the 1.0.0
* release (DG);
* 28-Mar-2005 : Fixed bug in getSeries(int) method (1170825) (DG);
* ------------- JFREECHART 1.0.x ---------------------------------------------
* 13-Dec-2005 : Deprecated the 'domainIsPointsInTime' flag as it is
* redundant. Fixes bug 1243050 (DG);
* 04-May-2007 : Override getDomainOrder() to indicate that items are sorted
* by x-value (ascending) (DG);
* 08-May-2007 : Added indexOf(TimeSeries) method (DG);
* 20-Jun-2007 : Removed deprecated code (DG);
* 21-Jun-2007 : Removed JCommon dependencies (DG);
