Release Notes: This release adds a notify flag to all datasets, key validation for the time series dataset, area fills for the XYSplineRenderer, a new axis label formatter, a new gradient paint transformer, improved handling of rotated text, and a number of bug fixes.
Release Notes: This release added subscript/superscript support for axis labels (via AttributedString), new axis label positioning options, simplified ChartFactory methods, new methods in DatasetUtilities for interpolating y-values in XYDatasets, URLs for labels on CategoryAxis, seamless integration with JFreeSVG and OrsonPDF, improved consistency of the SWTGraphics2D implementation, and fixes for various bugs. All JUnit tests have been upgraded to JUnit 4.
Release Notes: This release contains support for multiple and logarithmic axes with PolarPlot, optional drop-shadows in plot rendering, fitting polynomial functions to a data series, some performance improvements in the TimeSeriesCollection class, mouse wheel rotation of pie charts, improved Maven support, and numerous bugfixes.
Release Notes: This release contains major enhancements including mouse wheel zooming, panning, clipboard support, improved renderer support for series visibility flags, better performance for rendering of large time series datasets, improved mouse click support, additional support for heat map generation, various minor feature updates, and a good number of bugfixes.
Release Notes: This release adds support for minor tick marks and mapping datasets to more than one axis. An important fix was made for the XYSeries class (relating to the addOrUpdate() method). Numerous other bugs were fixed.
Release Notes: This release features a new chart theming mechanism to allow charts to be restyled conveniently, a new BarPainter mechanism to enhance the appearance of bar charts, a new XYShapeRenderer class, a scaling facility for the XYDrawableAnnotation for drawing the annotation within specific data coordinates, various other new classes (XYTaskDataset, XYDataImageAnnotation, and XYTitleAnnotation), a modification to the Year class to support an extended range, plus the usual slew of bugfixes and API improvements.
Release Notes: This release contains various bugfixes and minor enhancements to JFreeChart. PiePlot labelling has been enhanced with new curve options and more robust bounds checking. The BoxAndWhiskerRenderer now has a maximumBarWidth attribute, and 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.
Release Notes: This release contains a security fix for HTML image map generation, several minor API enhancements and a range of bug fixes.
Release Notes: This is primarily a bugfix release, correcting a problem with pie chart labelling, a regression in the DefaultCategoryDataset class (and underlying KeyedValues2D class), and a cloning bug in the TimeSeries class. In addition, the StatisticalBarRenderer class has a new "errorIndicatorStroke" field and has been updated to support gradients. The StandardDialScale has had some missing accessor methods implemented. An override field in the StandardXYItemRenderer class has been deprecated. Some warnings reported by FindBugs 1.3.0 have been addressed.
Release Notes: This release features the promotion of the DialPlot and LogAxis classes into the main API (previously in experimental), a new renderer for fitting spline curves to data points, an option for "simple" labeling on pie charts, many improvements to the statistical dataset implementations, numerous other improvements all over, and the usual slew of bugfixes.
