JFreeChart 1.0.10
-----------------
9 June 2008
This release contains various bug fixes and minor enhancements to JFreeChart.
PiePlot labelling has been enhanced (new curve options, and more robust bounds
checking). The BoxAndWhiskerRenderer now has a maximumBarWidth attribute, the
XYStepRenderer has a new stepPoint attribute. The RelativeDateFormat class
has new options. There are new dataset classes (SlidingCategoryDataset and
SlidingGanttDataset) that permit a subset of categories to be plotted, and
allow charts based on these datasets to simulate scrolling. There is a new
ShortTextTitle class.
This release passes 1,929 JUnit tests (0 failures) on JRE 1.6.0_03.
API Adjustments:
- BoxAndWhiskerRenderer - added maximumBarWidth attribute (see patch 1866446);
- ChartPanel - the zoomPoint attribute has been changed from Point to Point2D;
- DatasetUtilities - iterateCategoryRangeBounds() is deprecated, the method
has been renamed iterateRangeBounds(CategoryDataset) for consistency;
- DefaultKeyedValue - the constructor now prevents a null key;
- LogFormat - now has a 'powerLabel' attribute;
- ShortTextTitle - a new title class;
- SlidingCategoryDataset - new class;
- SlidingGanttDataset - new class;
- TimeSeriesCollection - getSeries(String) changed to getSeries(Comparable);
- XIntervalSeriesCollection - added series removal methods;
- YIntervalSeriesCollection - added series removal methods;
- XYIntervalSeriesCollection - added series removal methods;
PublicCloneable is now implemented by a number of classes that didn't
previously implement the interface - this should improve the reliability of
chart cloning.
Patches:

1925366 : Speed improvement for DatasetUtilities [Rafal Skalny];

The DatasetUtilities.sampleFunction2D() has been changed to sample the correct
number of points - you should check any code that calls this method. The
XYBlockRenderer class now generates entities. Bugs in the removeDomainMarker()
and removeRangeMarker() methods in the CategoryPlot and XYPlot classes have
been fixed. A bug in the TimePeriodValues range calculation has been fixed.
Fixes were applied to the clone() methods in the TaskSeries and
TaskSeriesCollection classes.
New Experimental Features:
Two new classes CombinedCategoryPlot and CombinedXYPlot have been added to the
'experimental' source tree - these were contributed by Richard West (see
patch 1924543).

standard API, but are included for developers to experiment with and provide
feedback on. Hopefully in the future, refined versions of these classes will
be incorporated into the main library. PLEASE NOTE THAT THE API FOR THESE
CLASSES IS SUBJECT TO CHANGE.
JFreeChart 1.0.1:
----------------
Released 27 January 2006. This is primarily a bug fix release. In addition,
there are some API adjustments (there should be no breakage of applications
coded to the 1.0.0 API).
API adjustments:
- BarRenderer: added a new flag (includeBaseInRange), plus accessor
methods, that controls whether or not the base value for the bar is
included in the range calculated by the findRangeBounds() method;

the BarRenderer class;

The flag serves no function now that renderers are used to calculate the
domain bounds, so you can safely delete any calls to the
setDomainIsPointsInTime() method;

- XYSeries: the update(int, Number) method has been deprecated and a new method
updateByIndex(int, Number) has been added;
