- -----------------
- 1. INTRODUCTION
- -----------------
- JFreeChart is a free chart library for the Java(tm) platform. It runs
- on the Java 2 Platform (JRE 1.6.0 or later) and uses the Java 2D API for
- drawing. There is also JavaFX support available, but requiring JDK 1.8.0 or
- later.
- 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.
- We are grateful to the many developers that have contributed to JFreeChart.
- The contributors are listed below in section 10.
- -------------------
- 2. LATEST VERSION
- -------------------
- The latest version of this class library can be obtained from:
- http://www.jfree.org/jfreechart/
- If you have any comments, suggestions or bugs to report, please post a
- message in the JFreeChart forum.
- -----------------
- 3. DOCUMENTATION
- -----------------
- You can download installation instructions
- (jfreechart-1.0.19-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' utility directly,
- or with the Ant script (build.xml) included in the distribution.
- -----------------
- 4. DEPENDENCIES
- -----------------
- JFreeChart has the following dependencies:
- (a) JRE/JDK 1.6.0 or higher. Note that JRE/JDK 1.8 is required to use the new
- JavaFX support (and you will need to rebuild the library using the
- ant/build-fx.xml script).
- (b) JCommon - the runtime jar file (version 1.0.23) 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) 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
- (d) 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/forum/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.
- --------------------
- 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/
- If you want to rebuild the JFreeChart jar file, we highly recommend that you
- use this script as it includes certain files (for example, .properties files)
- that you MUST have in the jar file for JFreeChart to function correctly.
- -----------------
- 7. MAVEN POM.XML
- -----------------
- A Maven pom.xml is included in the distribution, and you can use this to
- build JFreeChart *without* JavaFX support. If you want to include the JavaFX
- support classes, you'll need to modify the pom.xml file accordingly.
- Both JFreeChart and JCommon are available on the Central Repository:
- <dependency>
- <groupId>org.jfree</groupId>
- <artifactId>jfreechart</artifactId>
- <version>1.0.19</version>
- </dependency>
- <dependency>
- <groupId>org.jfree</groupId>
- <artifactId>jcommon</artifactId>
- <version>1.0.23</version>
- </dependency>
-
- ------------------------
- 8. 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 1.6.0 or later), use the following command:
- java -jar jfreechart-1.0.19-demo.jar
- The complete source code for the demo application is available for
- download when you purchase the JFreeChart Developer Guide.
- The demo application also links to the JFreeSVG and OrsonPDF libraries, to
- provide export facilities to the SVG and PDF formats. These fast, lightweight
- libraries are independent from JFreeChart. JFreeSVG is dual licensed under
- the GNU GPLv3 and a commercial license, while OrsonPDF is commercially licensed.
- Licenses can be purchased from Object Refinery Limited.
- An additional tab added to the demo application showcases Orson Charts, a
- 3D chart library by Object Refinery Limited. You can find out more about
- Orson Charts at:
- http://www.object-refinery.com/orsoncharts/
- ---------------
- 9. LIMITATIONS
- ---------------
- JFreeChart has some known limitations that will hopefully be addressed in
- the future:
- - 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;
- If there are other items that you think should be listed here,
- please post a bug report.

- - 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;

- 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

- - 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.

- 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();

- chart annotations. Improved control over renderers. Duplicate
- x-values now allowed in XYSeries. Optional category label
- skipping in category axes. Added CategoriesPaint attribute to

- - 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

- 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
