  • added support for multiple axes in PolarPlot, performance improvements in the TimeSeriesCollection class, mouse wheel rotation in the PiePlot class,
  • improved Maven support, a range of other minor functional enhancements and numerous bug fixes
  • see the NEWS and ChangeLog files for details.

New in JFreeChart 1.0.13 (Apr 21, 2009)

  • updates to the ChartPanel class to support copying charts to the clipboard, panning and mouse-wheel zooming, and an overlay mechanism that supports crosshairs;
  • enhancements to the auto-range calculation for axes, providing the ability to use subranges only and also to skip hidden series;
  • updates for many of the CategoryItemRenderer implementations to ensure that they respect the 'seriesVisible' flags;
  • an improvement to the TimeSeries class so that it is no longer necessary to specify the time period type in the constructor;
  • a new SamplingXYLineRenderer for improving the performance of time series charts with large datasets;
  • the XYSeries/XYSeriesCollection classes now cache the minimum and maximum data values to improve the performance of charts with large datasets;
  • entities are now created for the chart, data area and axes, allowing mouse clicks to be detected for these regions;
  • added a bar alignment factor to the XYBarRenderer class;
  • a new 'errorIndicatorStroke' field for the StatisticalLineAndShapeRenderer and XYErrorRenderer classes;
  • added a new HeatMapDataset interface, DefaultHeatMapDataset implementation, and a HeatMapUtilities class to make it easier to create heat map charts;
  • there is a new flag to allow an XYDataImageAnnotation to be included in the automatic range calculation for the axes;
  • additional attributes in the XYTextAnnotation class;
  • added a sampleFunction2DToSeries() method to the DatasetUtilities class;
  • some changes to the ChartPanel class that help to work around a regression in JRE 1.6.0_10 relating to drawing in XOR mode. Regarding this final point:
  • the default value for the useBuffer flag has changed to true, which means that all charts will, by default, be rendered into an off-screen image before being displayed in the ChartPanel;
  • the zoom rectangle is drawn using XOR mode *only* when the useBuffer flag has been set to false.
  • For most usage, this should improve performance (but at the cost of using more memory for each ChartPanel used in your application);
  • Bug Fixes:
  • 2690293 : Problem with Javascript escape characters;
  • 2617557 : StandardDialScale ignored tickLabelPaint;
  • 2612649 : Stroke selection in plot property editor;
  • 2583891 : SWTGraphics2D.fillPolygon() not implemented;
  • 2564636 : Month constructor ignores Locale;
  • 2502355 : ChartPanel sending multiple events;
  • 2490803 : PeriodAxis.setRange() method doesn't take into account that the axis displays whole periods;
  • In addition, a bug in the SlidingCategoryDataset class has been fixed, the
  • correct outline paint is now used by GradientXYBarPainter, a new method
  • has been added to the ImageMapUtilities class to escape special characters
  • in Javascript strings to avoid problems with the OverLIB and DynamicDrive
  • tooltips, and there are some important fixes in the LogAxis class.
  • This release passes 2110 JUnit tests (0 failures) on JRE 1.6.0_12.
