| 1. INTRODUCTION |
| ----------------- |
| JFreeChart is a free chart library for the Java(tm) platform. It runs |
| on the Java 2 Platform (JDK 1.3 or later) and uses the Java 2D API for |
| drawing. |
| |
| JFreeChart is licensed under the terms of the GNU Lesser General |
| Public Licence (LGPL). A copy of the licence is included in the |
| distribution. |
| |
| Please note that JFreeChart is distributed WITHOUT ANY WARRANTY; |
| without even the implied warranty of MERCHANTABILITY or FITNESS FOR A |
| PARTICULAR PURPOSE. Please refer to the licence for details. |
| |
| ------------------- |
| 2. LATEST VERSION |
| ------------------- |
| The latest version of this class library can be obtained from: |
| |
| http://www.jfree.org/jfreechart/ |
| |
| If you have an comments, suggestions or bugs to report, please post a |
| message in the JFreeChart forum. |
| |
| ----------------- |
| 3. DOCUMENTATION |
| ----------------- |
| You can download installation instructions |
| (jfreechart-1.0.8-install.pdf) from the JFreeChart home |
| page or the project page on SourceForge. |
| |
| Further documentation for JFreeChart (the JFreeChart Developer Guide) is |
| available to purchase from by Object Refinery Limited, a company owned and |
| operated by David Gilbert (the original author of JFreeChart). For more |
| information, please see: |
| |
| http://www.object-refinery.com/jfreechart/guide.html |
| |
| Sales of the JFreeChart Developer Guide are an important source of funding for |
| the project. Please help us to continue developing free software. |
| |
| API documentation files in HTML format are available on-line. If you wish |
| to keep a local copy of the API files, you can regenerate them directly |
| from the source code. You can do this using the 'javadoc' or 'gjdoc' |
| utilities directly, or with the Ant script (build.xml) included in the |
| distribution. |
| |
| ----------------- |
| 4. DEPENDENCIES |
| ----------------- |
| JFreeChart has the following dependencies: |
| |
| (a) JDK 1.3.1 or higher - JFreeChart requires the Java2D and Collections |
| APIs, so it definitely won't work with JDK 1.1 (with a small amount of effort |
| you can get it to compile and run with JDK 1.2). If you are using JFreeChart |
| to create applets, this means that you cannot rely on the JVM integrated with |
| Microsoft's Internet Explorer - your users will need to have the Java 2 |
| plug-in installed. Most other browsers (e.g. Firefox, Mozilla, Netscape, |
| Konqueror) support JRE 1.4, 1.5 or 1.6. |
| |
| (b) JCommon - version 1.0.0 or later. The runtime jar file (version 1.0.12) |
| is included in the JFreeChart distribution. You can obtain the complete |
| source code for JCommon from: |
| |
| http://www.jfree.org/jcommon/ |
| |
| JCommon is licensed under the terms of the GNU Lesser General Public Licence. |
| |
| (c) GNU JAXP (JDK 1.3 only) - a free implementation of the standard XML |
| processing APIs for Java. |
| |
| http://www.gnu.org/software/classpathx/jaxp/ |
| |
| Classes in the org.jfree.data.xml package require this library, or |
| another JAXP v1.1 compliant parser. The gnujaxp.jar file (from the |
| gnujaxp-1.0beta1.zip distribution) is included with JFreeChart. GNU |
| JAXP is licensed under the terms of the GNU General Public License |
| with an additional library exception. |
| |
| THIS LIBRARY IS ONLY REQUIRED BY JFREECHART IF YOU ARE USING JDK 1.3. |
| |
| (d) servlet.jar - classes in the org.jfree.chart.servlet |
| package require this file. The JFreeChart distribution includes the |
| servlet.jar file distributed with Tomcat 4.1.31. Applicable license |
| terms are published at: |
| |
| http://java.sun.com/products/servlet/LICENSE |
| |
| (e) JUnit - a unit testing framework (the junit.jar runtime file is |
| included in the distribution). JUnit is licensed under the terms |
| of the IBM Common Public License. You can find out more about JUnit |
| and/or download the latest version from: |
| |
| http://www.junit.org |
| |
| The JUnit tests included with JFreeChart have been created using JUnit |
| 4.3.1. |
| |

| 5. SUPPORT |
| ----------- |
| Support questions can be posted in the free support forum at |
| |
| http://www.jfree.org/phpBB2/viewforum.php?f=3 |
| |
| We read all questions posted in the forum, and respond to as many as we can |
| in the time available. Unfortunately, there are too many questions to answer |
| them all. |
| |
| If you need commercial support for JFreeChart, this is offered by |
| Object Refinery Limited: |
| |
| http://www.object-refinery.com/jfreechart/support.html |
| |
| -------------------- |
| 6. ANT BUILD SCRIPT |
| -------------------- |
| An Ant build script (build.xml) is included in the distribution. This |
| is the same script that is used to create the JFreeChart distribution. |
| |
| For more information about Ant: |
| |
| http://ant.apache.org/ |
| |
| Please note that you will need to obtain the servlet.jar file (see the |
| DEPENDENCIES section above) before running the Ant script. |
| |
| ------------------------ |
| 7. THE DEMO APPLICATION |
| ------------------------ |
| A demo application that shows a selection of the charts that can be |
| generated is included in the JFreeChart distribution. To run the |
| demo (using JDK 1.3.1 or later), use the following command: |
| |
| java -jar jfreechart-1.0.8-demo.jar |
| |
| The complete source code for the demo application is available for |
| download when you purchase the JFreeChart Developer Guide. |
| |
| The demo application uses iText, a library for creating PDF documents. |
| iText is licensed under the terms of the GNU Lesser General Public Licence |
| and is available to download from: |
| |
| http://www.lowagie.com/iText/ |
| |
| --------------- |
| 8. LIMITATIONS |
| --------------- |
| JFreeChart has some known limitations that will hopefully be addressed in |
| the future: |
| |
| - with the XYPlot class, when the bounds of the range axis are calculated |
| automatically, all of the data is used, not just the subset that is |
| visible on the chart; |
| - some renderers do not respect the series visibility flags yet; |
| - the chart property editors (accessible by right-clicking on the chart |
| panel) are horribly out of date and probably shouldn't be used; |
| - item labels (if displayed) are not taken into account for the |
| automatically calculated axis range. As a workaround, you can increase |
| the axis margins; |
| - tick labels on a DateAxis that uses a SegmentedTimeline can be |
| problematic; |
| - there is no support for writing charts to JPEG format on JDK 1.3. JPEG |
| is not a good format for charts in any case, and it is usually better to |
| use PNG format. |
| |
| If there are other items that you think should be listed here, |
| please post a bug report. |
| |
| ----------------- |
| 9. GNU CLASSPATH |
| ----------------- |
| GNU Classpath is a project to create a free, clean-room implementation of the |
| standard Java(tm) class libraries: |
| |
| http://www.gnu.org/software/classpath/ |
| |
| JFreeChart should work quite well with free runtimes based on |
| GNU Classpath 0.92 or later. We are grateful to all the GNU Classpath |
| developers that have made this possible. |

| |
| - merged the HorizontalCategoryPlot and VerticalCategoryPlot classes, |
| into the CategoryPlot class; |
| - merged the horizontal and vertical axis classes; |
| - merged the horizontal and vertical renderer classes; |
| - CategoryPlot and XYPlot now support both horizontal and vertical |
| orientation via the setOrientation(...) method; |
| - merged horizontal and vertical methods in the ChartFactory class; |
| - created new combined plot classes: CombinedDomainCategoryPlot, |
| CombinedRangeCategoryPlot, CombinedDomainXYPlot and |
| CombinedRangeXYPlot (these can all be drawn with a horizontal or |
| vertical orientation); |
| - Bill Kelemen has enhanced the DateAxis class to handle segmented |
| timelines. This can be used, for example, to skip weekends for |
| daily stock price charts; |
| - Richard Atkinson has updated the ServletUtilities class; |
| - Bryan Scott has added an XYDatasetTableModel class for presenting |
| datasets in a JTable; |
| - modified XYPlot to allow renderers to use multiple passes through |
| the dataset; |
| - added new XYDifferenceRenderer; |
| - added support for colored bands between gridlines in XYPlot; |
| - added new XYDrawableAnnotation class; |
| - added a new attribute to control the order of dataset rendering in |
| a CategoryPlot; |
| - extended the value label mechanism for the renderers, to allow |
| better (per series) control over label generation, positioning and |
| visibility; |
| - CategoryItemTooltipGenerator has been renamed |
| CategoryItemLabelGenerator, since it is now being used to generated |
| item labels as well as tooltips; |

| make it easier to create histograms with JFreeChart; |
| - moved the DrawingSupplier into the plot class, renderers now |
| reference the supplier from the plot (parent plot for combined and |
| overlaid charts). This means that renderers now share a single |
| DrawingSupplier by default, which simplifies the creation of |
| combined charts; |
| - changed the ColorBarAxis classes that extended the NumberAxis class, |
| to a single ColorBar class that wraps a ValueAxis (may have broken |
| one or two things in the process); |
| - Barak Naveh has contributed new classes MatrixSeries and |
| MatrixSeriesCollection, along with demos: BubblyBubblesDemo.java |

| require further testing); |
| - incorporated contour plot updates from David M. O'Donnell; |
| - added new CategoryTextAnnotation and XYLineAnnotation |
| classes; |
| - added new HorizontalCategoryAxis3D class contributed by |
| Klaus Rheinwald; |
| |
| Bug fixes: |
| - added a workaround for JVM crash (a JDK bug) in pie charts |
| with small sections (see bug report 620031); |

| report 690865); |
| - added pieIndex parameter to tooltip and URL generators for |
| pie charts; |
| - fixed bug in getLastMillisecond() method for the Second |
| class and the getFirstMillisecond() method for the Year |
| class (picked up in JUnit tests); |
| - in TextTitle, changed width used for relative spacing to fix |
| bug 703050; |
| |

| - fixed null pointer exception in DefaultCategoryDataset; |
| - fixed update problem for PaintTable, StrokeTable and |
| ShapeTable objects; |
| - added methods to control colors in PiePlot (these were |
| inadvertantly removed in the changes made for 0.9.5); |
| - fixed auto-range update problem for secondary axis; |
| - fixed missing category labels in the overlaid category plot; |
| - fixed constructors for symbolic axes; |
| - corrected error in Javadoc generation (Ant script); |
| |
| 0.9.5 : (6-Feb-2003) PLEASE NOTE THAT MAJOR CHANGES TO THE |
| JFREECHART API HAVE BEEN MADE IN THIS RELEASE! |
| |
| - added support for secondary axes, datasets and renderers; |
| - added new data interfaces (Value, Values, Values2D, |
| KeyedValues and KeyedValues2D) and incorporated these into |
| the existing PieDataset and CategoryDataset interfaces. |
| - modified the CategoryDataset interface to be more |
| symmetrical, data is organised in rows and columns (as |
| before) but can now be accessed by row/column index or |
| row/column key. |
| - added support for reading PieDatasets and CategoryDatasets |
| from XML files. |
| - created separate packages for the axes |
| (com.jrefinery.chart.axis), plots (com.jrefinery.chart.plot) |
| and renderers (com.jrefinery.chart.renderer). |
| - series attributes (paint, outline paint, stroke and shape) |
| are now controlled by the renderer classes using lookup |
| tables. Introduced the DrawingSupplier interface (and |
| DefaultDrawingSupplier class) which is used to populate the |
| lookup tables from a common source (necessary to coordinate |
| complex combined charts). |
| - the chart legend can now display shapes corresponding to |
| series. |
| - moved responsibility for category distribution to the |
| CategoryAxis class, which tidies up the code in the |
| CategoryPlot classes. |
| - gridlines are now controlled by the CategoryPlot and XYPlot |
| classes, not the axes (included in this change is the |
| addition of gridlines for the CategoryPlot domain values). |
| - changed the list of titles in the JFreeChart class to a |
| title and a list of subtitles. |
| - added new renderers for XYPlot (XYBubbleRenderer and |
| YIntervalRenderer). |
| - modified Gantt chart to display sub-tasks. |
| - added ContourPlot class (still experimental) by David |
| M. O'Donnell. |
| - introduced new MovingAverage class. |
| - ChartMouseEvent now includes source chart. |
| - numerous bug fixes. |
| - lots of Javadoc updates. |
| |
| 0.9.4 : (18-Oct-2002) Added a new stacked area chart (contributed by Dan |
| Rivett) and a compass plot (contributed by Bryan Scott). Updated |
| the ThermometerPlot class. Added a new XYDotRenderer for scatter |
| plots. Modified combined and overlaid plots to use the series colors |
| specified in the sub plot rather than the parent plot (this makes it |
| easier to align the colors in the legend). Added Regression class |
| for linear and power regressions. BasicTimeSeries can now |
| automatically drop "old" data. Some clean-up work in the code for |
| tooltips and the event listener mechanism. Richard Atkinson has |
| incorporated some useful extensions for servlets/JSP developers. |
| |
| Ran Checkstyle and corrected issues reported for most classes. |
| Checkstyle is a free utility that you can download from: |
| |
| http://checkstyle.sourceforge.net |
| |
| Fixed bugs and updated documentation. |
| |
| API changes include: |
| - added tickMarkPaint to Axis constructor (also affects |
| subclasses); |
| - added getLegendItems() to Plot, and deprecated |
| getLegendItemLabels(); |
| - added getLegendItem(int) to XYItemRenderer and |
| CategoryItemRenderer. |
| - most 'protected' member variables have been changed to |
| 'private'. |
| |
| 0.9.3 : (4-Sep-2002) Added multiple pie charts based on |
| CategoryDataset. Updated logarithmic axes. Improved URL |
| support for image map generation. Moved the com.jrefinery.data |
| package from JCommon to JFreeChart. Added simple framework for |
| chart annotations. Improved control over renderers. Duplicate |
| x-values now allowed in XYSeries. Optional category label |
| skipping in category axes. Added CategoriesPaint attribute to |
| AbstractCategoryItemRenderer. Added new attributes to |
| MeterPlot class. Updated 3D pie chart to observe start angle |
| and direction, and also foreground alpha < 1.0. Improved |
| Javadoc comments. New demo applications, including: |
| AnnotationDemo1, EventFrequencyDemo, JDBCCategoryChartDemo, |
| JDBCPieChartDemo, JDBCXYChartDemo and MinMaxCategoryPlotDemo. |
| Bug fixes: |
| - negative percentages on PiePlot. |
| - added listener notification to setXXXAxis(...) methods. |
| - fixed DomainInfo method name clash. |
| - added DomainIsPointsInTime flag to TimeSeriesCollection to |
| give better control over auto range on axis for time series |
| charts. |
| - axis margins for date axes are no longer hard-coded. |
| - fix for ordering of categories in JdbcCategoryDataset. |
| - added check for null axis in mouse click handler. |
| |
| The CVS repository at SourceForge has also been restructured |
| to match the distribution directory layout. |
| |
| 0.9.2 : (28-Jun-2002) PiePlot now has startAngle and direction |
| attributes. Added support for image map generation. Added a |
| new Pie3DPlot class. Added label drawing code to bar |
| renderers. Added optional range markers to horizontal number |
| axis. Added bar clipping to avoid PRExceptions in bar |
| charts. JFreeChartDemo has been modified and now includes |
| examples of the dial and thermometer plots. |
| Bug fixes: |
| - auto range for VerticalNumberAxis when zero is forced to be |
| included in the range. |

| - check for null popup menu in ChartPanel.mouseDragged; |
| - new checks for null info in renderers; |
| - range markers now drawn only if in visible axis range; |
| |
| 0.9.0 : (7-Jun-2002) New plots including an area chart, a horizontal |
| 3D bar chart, a Gantt chart and a thermometer chart. |
| Combination plots have been reworked to provide a |
| simpler framework, and extends to allow category plots to be |
| combined. There is now a facility to add a ChartMouseListener |
| to the ChartPanel (formerly JFreeChartPanel). An interactive |
| zooming feature (experimental at this point) is now available |
| for XYPlots. A new Polish translation has been added. Several |
| fixes have been applied to the default tool tip generators. A |
| workaround has been added to fix the alignment between time |
| series charts and the date axis. There are some improvements |
| to the VerticalLogarithmicAxis class, and now a corresponding |
| HorizontalLogarithmicAxis class. Additional demonstration |
| applications have been added. Fixed the popup menu bug. |
| |
| 0.8.1 : (5-Apr-2002) Localised resource bundles for French, German and |
| Spanish languages (thanks to Anthony Boulestreau, Thomas Meier |
| and Hans-Jurgen Greiner for the translations). An area XY |
| plot and meter chart contributed by Hari. Symbol charts |
| contributed by Anthony Boulestreau. An improved |
| CandleStickRenderer class from Sylvain Vieujot. Updated |
| servlet code from Bryan Scott. XYItemRenderers now have a |
| change listener mechanism and therefore do not have to be |
| immutable. Additional demonstration applications for |
| individual chart types. Minor bug fixes. |
| |
| 0.8.0 : (22-Mar-2002) All the category plots are now controlled |
| through the one class (CategoryPlot) with plug-in renderers. |
| Added a ResourceBundle for user interface items that require |
| localisation. Added a logarithmic axis class contributed by |
| Mike Duffy and some new JDBC and servlet code contributed by |
| Bryan Scott. Updated the JCommon class library to improve |
| handling of time periods in different time zones. |
| |
| 0.7.4 : (6-Mar-2002) Bug fixes in the JCommon Class Library. Various |
| Javadoc comment updates. Some minor changes to the |
| code. Added new domain name (http://www.object-refinery.com) |
| in the source headers. |
| |
| 0.7.3 : (14-Feb-2002) Bug fixes. |
| |
| 0.7.2 : (8-Feb-2002) Integrated the WindPlot code from Achilleus |
| Mantzios. Added an optional background image for the |
| JFreeChart class, and another optional background image for |
| the Plot class. Added alpha-transparency for the plot |
| foreground and background. Added new pie chart label types |
| that show values. Fixed a bug with the legend that results in |
| a loop at small chart sizes. Added some tooltip methods that |
| were missing from the previous version. Changed the Insets |
| class on chart titles to a new Spacer class that will allow |
| for relative or absolute insets (the plan is to eventually |
| replace all Insets in the JFreeChart classes). Fixed a bug in |
| the setAutoRangeIncludesZero method of the NumberAxis class. |
| Added the instructions that were missing from the copies of |
| the GNU Lesser General Public Licence included with JFreeChart. |
| |
| 0.7.1 : (25-Jan-2002) Added tooltips, crosshairs and zooming |
| functions, thanks to Jonathan Nash and Hans-Jurgen Greiner |
| for contributing the code that these features are based on. |
| Moved the combination charts into the package |
| com.jrefinery.chart.combination, made a number of other small |
| API changes and fixed some bugs. Removed the Javadoc HTML |
| from the download to save space (you can regenerate it from |
| the source code if you need it). |
| |
| 0.7.0 : (11-Dec-2001) New combination plots developed by Bill |
| Kelemen. Added Wolfgang Irler's servlet demo to the standard |
| download. The About window in the demo application now |
| includes a list of developers that have contributed to the |
| project. |
| |
| 0.6.0 : (27-Nov-2001) New plots including scatter plot, stacked bar |
| charts and 3D bar charts. Improved pie chart. Data |
| interfaces and classes moved to the JCommon class library. |
| New properties to control spacing on bar charts. New |
| auto-tick mechanism. JFreeChartPanel now incorporates |
| buffering, and popup menu. Javadocs revised. Fixed numerous |
| bugs from version 0.5.6. Demo application updated. |
