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 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 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.
Release Notes: This release features a new class (DeviationRenderer) that is useful for time series forecast charts. It also adds support for item labels in stacked bar charts, tooltips and URLs in step charts, and many bugfixes.
Release Notes: New features in this release include support for URLs for pie chart labels, a new dataset for open-high-low-close charts, support for GradientPaint in various bar charts, a new XYBlockRenderer, improvements to the experimental SWT support, and many bugfixes.
Release Notes: This release features a range of usability enhancements in the API, two new array-based dataset classes, various performance enhancements in the renderer classes, and numerous bugfixes. In addition, the distribution includes some new experimental classes, including support for the Standard Widget Toolkit (SWT) via a custom SWTGraphics2D class, a new LogAxis class, and a block renderer.
Release Notes: This release contains new support for "stacked 100%" bar charts, improvements to the chart legend mechanism, a large number of bugfixes, and many other minor enhancements.
Release Notes: New axis classes were added (PeriodAxis and ModuloAxis), the org.jfree.chart.renderer and org.jfree.data packages were reorganized, a new "umbrella" demo that makes it easier to browse the numerous included demos was added, and various bugs were fixed.
Release Notes: Methods that return double primitives were added to XYDataset. The distinction between "primary" and "secondary" datasets, renderers, and axes was removed. Fixed legend item options were added to CategoryPlot and XYPlot. Legend enhancements were made. The Log4j dependency was removed. Many bugfixes were made.
