JFreeChart 1.0.13 ----------------- 20 April 2009 ****************************************************************************** * SPECIAL NOTICE: There will be a birds-of-a-feather session for JFreeChart * * at this year's JavaOne conference in San Francisco. The session is * * scheduled for 6.45pm to 7.35pm on Wednesday 3 June. * ****************************************************************************** This release contains: - 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.

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.

A new DialPlot implementation has been added to the 'experimental' sources. We are looking for people to test this code and provide feedback, so that we can stabilize the API and add this code to the main JFreeChart API. API adjustments: The following adjustments have been made to the API: - CategoryLabelEntity - new class; - CategoryPointerAnnotation - new class; - ChartPanel: added new public method doEditChartProperties(); - ComparableObjectItem, ComparableObjectSeries - new classes; - CrosshairState: added several new accessor methods; - DefaultPieDataset: added sortByKeys() and sortByValues() methods; - Markers: a change event mechanism has been added to the Marker class and its subclasses; - StackedAreaRenderer: added get/setRenderAsPercentages() methods; - XIntervalDataItem, XIntervalSeries and XIntervalSeriesCollection - new classes; - XYErrorRenderer: new class; - XYInterval, XYIntervalDataItem, XYIntervalSeries and XYIntervalSeriesCollection - new classes; - YInterval, YIntervalDataItem, YIntervalSeries, YIntervalSeriesCollection and YWithXInterval - new classes. Bug Fixes: 1578293 - Unused methods in JDBCXYDataset; 1572478 - BoxAndWhiskerRenderer potential NullPointerException; 1569094 - XYStepRenderer with horizontal orientation; 1565168 - Crosshair position incorrect; 1564977 - DateAxis missing initial tick label; 1562759 - StatisticalLineAndShapeRenderer constructor ignores arguments; 1557141 - Bad locale in ServletUtilities; 1550045 - TimeSeries.removeAgedItems() method problems; 1549218 - Chart not displaying when all data values are the same and large; 1450447 - Marker.setAlpha() ignored; Also fixed URL generation for legend items, tick mark positioning on the DateAxis, the equals() method in the AreaRenderer class, hardcoded outline attributes in the XYBubbleRenderer, and potential NullPointerExceptions in the ChartPanel class. JFreeChart 1.0.2: ----------------- Released on 25 August 2006. API adjustments: The following adjustments have been made to the API (there should be no breakage of applications coded to the 1.0.0 or 1.0.1 API): - CategoryToPieDataset: added accessor methods for underlying dataset, extract type and index (feature request 1477915); - DefaultXYDataset: New dataset implementation that uses double[] arrays; - DefaultXYZDataset: New dataset implementation that uses double[] arrays; - LegendItemBlockContainer: New container used in legends (enables legend item entities again); - MultiplePiePlot: Added new fields aggregatedItemsKey and aggregatedItemsPaint, plus accessor methods - see bug 1190647; - SpiderWebPlot: Added new fields toolTipGenerator and urlGenerator, plus accessor methods (see patch 1463455); - StackedBarRenderer3D: Added new flag (renderAsPercentages), plus accessor methods, that controls whether the data items are displayed as values or percentages. Two new constructors are also added (see patch 1459313); - XYPolygonAnnotation: Added new accessor methods. Patches: 1459313 - Add renderAsPercentages option to StackedBarRenderer3D; 1462727 - Modify SpiderWebPlot to support zero values; 1463455 - Modify SpiderWebPlot to support mouse clicks, tool tips and URLs; Bug Fixes: 1514904 - Background image alpha in Plot class; 1499140 - ClusteredXYBarRenderer with margin not drawing correctly; 1494936 - LineAndShapeRenderer generates entity for non-visible item; 1493199 - NPE drawing SpiderWebPlot with null info; 1480978 - AbstractPieItemLabelGenerator.clone() doesn't clone percentFormat; 1472942 - DateAxis.equals() broken; 1468794 - StatisticalLineAndShapeRenderer doesn't draw error bars correctly when the plot has a horizontal orientation; - AbstractCategoryItemRenderer doesn't check seriesVisibleInLegend flag before creating new item; 1440415 - Bad distribution of pie chart section labels; 1440346 - Bad manifest entry for JCommon in JFreeChart jar file; 1435461 - NumberAxis.equals() ignores rangeType field; 1435160 - XYPointerAnnotation.equals() ignores x and y fields; 1398672 - LegendItemEntities not working; 1380480 - StandardXYItemRenderer problems with Double.NaN; 1190647 - Legend and section color mismatch for MultiplePiePlot. Miscellaneous Changes: - Updated CandlestickRenderer, CyclicXYItemRenderer, HighLowRenderer, XYStepAreaRenderer and TimeSeriesURLGenerator to call dataset methods that return double primitive only; - Updated XYPolygonAnnotation, adding new accessor methods and fixing problems in the equals()/hashCode() methods; - ChartFactory.createStackedXYAreaChart() now uses StackedXYAreaRenderer2, for better handling of negative values; - Added crosshair support for XYBarRenderer. Experimental Code: In this release, some new (incomplete) classes have been included in the org.jfree.experimental.* namespace. These classes are not part of the 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; - BubbleXYItemLabelGenerator: new class; - Range: added a new method expandToInclude(Range, double), this is used by the BarRenderer class; - TaskSeriesCollection: added two new methods, getSeries(int) and getSeries(Comparable). - TimeSeriesCollection: the domainIsPointsInTime flag has been deprecated. 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; - XYPlot: added a new getAnnotations() method; - XYSeries: the update(int, Number) method has been deprecated and a new method updateByIndex(int, Number) has been added; Bug fixes: 1243050 - XYBarRenderer doesn't show entire range of values for a TimeSeriesCollection; 1373371 - XYBubbleRenderer doesn't support item labels; 1374222 - BarRenderer contains JDK 1.4 specific code; 1374328 - LegendItem serialization problem; 1377239 - Bad argument checking in Quarter constructor; 1379331 - Incorrect drawing of TextTitle at LEFT or RIGHT position; 1386328 - RingPlot entity incorrect; 1400442 - Inconsistent treatment of null and zero values in PiePlot; 1401856 - Bad rendering for non-zero base values in BarRenderer; 1403043 - NullPointerException in CategoryAxis; 1408904 - NumberAxis3D assumes CategoryPlot; 1415480 - XYTextAnnotation equals() method doesn't check (x, y); JFreeChart 1.0.0: ---------------- Released on 2 December 2005.
