101. INTRODUCTION
11-----------------
12JFreeChart is a free chart library for the Java(tm) platform. It runs
13on the Java 2 Platform (JDK 1.3 or later) and uses the Java 2D API for
14drawing.
15
16JFreeChart is licensed under the terms of the GNU Lesser General
17Public Licence (LGPL). A copy of the licence is included in the
18distribution.

353. DOCUMENTATION
36-----------------
37You can download installation instructions
38(jfreechart-1.0.8-install.pdf) from the JFreeChart home
39page or the project page on SourceForge.
40
41Further documentation for JFreeChart (the JFreeChart Developer Guide) is
42available to purchase from by Object Refinery Limited, a company owned and
43operated by David Gilbert (the original author of JFreeChart). For more
44information, please see:
45
46 http://www.object-refinery.com/jfreechart/guide.html
47
48Sales of the JFreeChart Developer Guide are an important source of funding for
49the project. Please help us to continue developing free software.
50
51API documentation files in HTML format are available on-line. If you wish
52to keep a local copy of the API files, you can regenerate them directly
53from the source code. You can do this using the 'javadoc' or 'gjdoc'
54utilities directly, or with the Ant script (build.xml) included in the
55distribution.
56
57-----------------
584. DEPENDENCIES
59-----------------
60JFreeChart has the following dependencies:
61
62(a) JDK 1.3.1 or higher - JFreeChart requires the Java2D and Collections
63APIs, so it definitely won't work with JDK 1.1 (with a small amount of effort
64you can get it to compile and run with JDK 1.2). If you are using JFreeChart
65to create applets, this means that you cannot rely on the JVM integrated with
66Microsoft's Internet Explorer - your users will need to have the Java 2
67plug-in installed. Most other browsers (e.g. Firefox, Mozilla, Netscape,
68Konqueror) support JRE 1.4, 1.5 or 1.6.
69
70(b) JCommon - version 1.0.0 or later. The runtime jar file (version 1.0.12)
71is included in the JFreeChart distribution. You can obtain the complete
72source code for JCommon from:
73
74 http://www.jfree.org/jcommon/
75
76JCommon is licensed under the terms of the GNU Lesser General Public Licence.
77
78(c) GNU JAXP (JDK 1.3 only) - a free implementation of the standard XML
79processing APIs for Java.
80
81 http://www.gnu.org/software/classpathx/jaxp/
82
83Classes in the org.jfree.data.xml package require this library, or
84another JAXP v1.1 compliant parser. The gnujaxp.jar file (from the
85gnujaxp-1.0beta1.zip distribution) is included with JFreeChart. GNU
86JAXP is licensed under the terms of the GNU General Public License
87with an additional library exception.
88
89THIS LIBRARY IS ONLY REQUIRED BY JFREECHART IF YOU ARE USING JDK 1.3.
90
91(d) servlet.jar - classes in the org.jfree.chart.servlet
92package require this file. The JFreeChart distribution includes the
93servlet.jar file distributed with Tomcat 4.1.31. Applicable license
94terms are published at:
95
96 http://java.sun.com/products/servlet/LICENSE
97
98(e) JUnit - a unit testing framework (the junit.jar runtime file is
99included in the distribution). JUnit is licensed under the terms
100of the IBM Common Public License. You can find out more about JUnit
101and/or download the latest version from:
102
103 http://www.junit.org
104
105The JUnit tests included with JFreeChart have been created using JUnit
1064.3.1.

124--------------------
1256. ANT BUILD SCRIPT
126--------------------
127An Ant build script (build.xml) is included in the distribution. This
128is the same script that is used to create the JFreeChart distribution.
129
130For more information about Ant:
131

133
134Please note that you will need to obtain the servlet.jar file (see the
135DEPENDENCIES section above) before running the Ant script.
136
137------------------------
1387. THE DEMO APPLICATION
139------------------------
140A demo application that shows a selection of the charts that can be
141generated is included in the JFreeChart distribution. To run the
142demo (using JDK 1.3.1 or later), use the following command:
143
144 java -jar jfreechart-1.0.8-demo.jar
145
146The complete source code for the demo application is available for
147download when you purchase the JFreeChart Developer Guide.
148
149The demo application uses iText, a library for creating PDF documents.
150iText is licensed under the terms of the GNU Lesser General Public Licence
151and is available to download from:
152
153 http://www.lowagie.com/iText/
154
155---------------
1568. LIMITATIONS
157---------------
158JFreeChart has some known limitations that will hopefully be addressed in
159the future:
160
161 - with the XYPlot class, when the bounds of the range axis are calculated
162 automatically, all of the data is used, not just the subset that is
163 visible on the chart;
164 - some renderers do not respect the series visibility flags yet;
165 - the chart property editors (accessible by right-clicking on the chart
166 panel) are horribly out of date and probably shouldn't be used;
167 - item labels (if displayed) are not taken into account for the
168 automatically calculated axis range. As a workaround, you can increase
169 the axis margins;
170 - tick labels on a DateAxis that uses a SegmentedTimeline can be
171 problematic;
172 - there is no support for writing charts to JPEG format on JDK 1.3. JPEG
173 is not a good format for charts in any case, and it is usually better to
174 use PNG format.
175
176If there are other items that you think should be listed here,
177please post a bug report.
178
179-----------------
1809. GNU CLASSPATH
181-----------------
182GNU Classpath is a project to create a free, clean-room implementation of the
183standard Java(tm) class libraries:
184
185http://www.gnu.org/software/classpath/
186
187JFreeChart should work quite well with free runtimes based on
188GNU Classpath 0.92 or later. We are grateful to all the GNU Classpath
189developers that have made this possible.

384
385 - merged the HorizontalCategoryPlot and VerticalCategoryPlot classes,
386 into the CategoryPlot class;
387 - merged the horizontal and vertical axis classes;
388 - merged the horizontal and vertical renderer classes;
389 - CategoryPlot and XYPlot now support both horizontal and vertical
390 orientation via the setOrientation(...) method;
391 - merged horizontal and vertical methods in the ChartFactory class;
392 - created new combined plot classes: CombinedDomainCategoryPlot,

394 CombinedRangeXYPlot (these can all be drawn with a horizontal or
395 vertical orientation);
396 - Bill Kelemen has enhanced the DateAxis class to handle segmented
397 timelines. This can be used, for example, to skip weekends for
398 daily stock price charts;
399 - Richard Atkinson has updated the ServletUtilities class;
400 - Bryan Scott has added an XYDatasetTableModel class for presenting
401 datasets in a JTable;
402 - modified XYPlot to allow renderers to use multiple passes through
403 the dataset;
404 - added new XYDifferenceRenderer;

406 - added new XYDrawableAnnotation class;
407 - added a new attribute to control the order of dataset rendering in
408 a CategoryPlot;
409 - extended the value label mechanism for the renderers, to allow
410 better (per series) control over label generation, positioning and
411 visibility;
412 - CategoryItemTooltipGenerator has been renamed
413 CategoryItemLabelGenerator, since it is now being used to generated
414 item labels as well as tooltips;

419 - added a new HistogramDataset class (contributed by Jelai Wang) to
420 make it easier to create histograms with JFreeChart;
421 - moved the DrawingSupplier into the plot class, renderers now
422 reference the supplier from the plot (parent plot for combined and
423 overlaid charts). This means that renderers now share a single
424 DrawingSupplier by default, which simplifies the creation of
425 combined charts;
426 - changed the ColorBarAxis classes that extended the NumberAxis class,
427 to a single ColorBar class that wraps a ValueAxis (may have broken
428 one or two things in the process);

448 - minor bug fixes;
449
4500.9.7 : (11-Apr-2003)
451 - added a new ValueDataset interface and DefaultValueDataset
452 class, and changed the CompassPlot class to use this instead
453 of MeterDataset;
454 - added DataUtilities class, to support creation of Pareto
455 charts (new demo included);
456 - updated writeImageMap method as suggested by Xavier Poinsard
457 (see Feature Request 688079);
458 - implemented Serializable for most classes (this is likely to
459 require further testing);
460 - incorporated contour plot updates from David M. O'Donnell;
461 - added new CategoryTextAnnotation and XYLineAnnotation
462 classes;
463 - added new HorizontalCategoryAxis3D class contributed by

478 class and the getFirstMillisecond() method for the Year
479 class (picked up in JUnit tests);
480 - in TextTitle, changed width used for relative spacing to fix
481 bug 703050;
482
4830.9.6 : (17-Feb-2003) Bug fixes:
484 - fixed null pointer exception in DefaultCategoryDataset;
485 - fixed update problem for PaintTable, StrokeTable and
486 ShapeTable objects;
487 - added methods to control colors in PiePlot (these were
488 inadvertantly removed in the changes made for 0.9.5);
489 - fixed auto-range update problem for secondary axis;
490 - fixed missing category labels in the overlaid category plot;
491 - fixed constructors for symbolic axes;

493
4940.9.5 : (6-Feb-2003) PLEASE NOTE THAT MAJOR CHANGES TO THE
495 JFREECHART API HAVE BEEN MADE IN THIS RELEASE!
496
497 - added support for secondary axes, datasets and renderers;
498 - added new data interfaces (Value, Values, Values2D,
499 KeyedValues and KeyedValues2D) and incorporated these into
500 the existing PieDataset and CategoryDataset interfaces.
501 - modified the CategoryDataset interface to be more
502 symmetrical, data is organised in rows and columns (as
503 before) but can now be accessed by row/column index or
504 row/column key.
505 - added support for reading PieDatasets and CategoryDatasets
506 from XML files.
507 - created separate packages for the axes
508 (com.jrefinery.chart.axis), plots (com.jrefinery.chart.plot)
509 and renderers (com.jrefinery.chart.renderer).
510 - series attributes (paint, outline paint, stroke and shape)
511 are now controlled by the renderer classes using lookup
512 tables. Introduced the DrawingSupplier interface (and
513 DefaultDrawingSupplier class) which is used to populate the
514 lookup tables from a common source (necessary to coordinate
515 complex combined charts).
516 - the chart legend can now display shapes corresponding to
517 series.
518 - moved responsibility for category distribution to the
519 CategoryAxis class, which tidies up the code in the
520 CategoryPlot classes.
521 - gridlines are now controlled by the CategoryPlot and XYPlot
522 classes, not the axes (included in this change is the
523 addition of gridlines for the CategoryPlot domain values).
524 - changed the list of titles in the JFreeChart class to a
525 title and a list of subtitles.
526 - added new renderers for XYPlot (XYBubbleRenderer and
527 YIntervalRenderer).
528 - modified Gantt chart to display sub-tasks.
529 - added ContourPlot class (still experimental) by David
530 M. O'Donnell.
531 - introduced new MovingAverage class.

533 - numerous bug fixes.
534 - lots of Javadoc updates.
535
5360.9.4 : (18-Oct-2002) Added a new stacked area chart (contributed by Dan
537 Rivett) and a compass plot (contributed by Bryan Scott). Updated
538 the ThermometerPlot class. Added a new XYDotRenderer for scatter
539 plots. Modified combined and overlaid plots to use the series colors
540 specified in the sub plot rather than the parent plot (this makes it
541 easier to align the colors in the legend). Added Regression class
542 for linear and power regressions. BasicTimeSeries can now
543 automatically drop "old" data. Some clean-up work in the code for
544 tooltips and the event listener mechanism. Richard Atkinson has
545 incorporated some useful extensions for servlets/JSP developers.
546
547 Ran Checkstyle and corrected issues reported for most classes.
548 Checkstyle is a free utility that you can download from:
549
550 http://checkstyle.sourceforge.net

558 getLegendItemLabels();
559 - added getLegendItem(int) to XYItemRenderer and
560 CategoryItemRenderer.

599 - auto range for VerticalNumberAxis when zero is forced to be
600 included in the range.
601 - fixed null pointer exception in StackedVerticalBarRenderer3D;
602 - Added get/set methods for min/max chart drawing dimensions
603 in ChartPanel;
604 - HorizontalIntervalBarRenderer now handles single category;
605 - verticalTickLabels now possible in HorizontalNumberAxis3D;

615
6160.9.0 : (7-Jun-2002) New plots including an area chart, a horizontal
617 3D bar chart, a Gantt chart and a thermometer chart.
618 Combination plots have been reworked to provide a
619 simpler framework, and extends to allow category plots to be
620 combined. There is now a facility to add a ChartMouseListener
621 to the ChartPanel (formerly JFreeChartPanel). An interactive
622 zooming feature (experimental at this point) is now available
623 for XYPlots. A new Polish translation has been added. Several
624 fixes have been applied to the default tool tip generators. A
625 workaround has been added to fix the alignment between time
626 series charts and the date axis. There are some improvements
627 to the VerticalLogarithmicAxis class, and now a corresponding
628 HorizontalLogarithmicAxis class. Additional demonstration
629 applications have been added. Fixed the popup menu bug.
630
6310.8.1 : (5-Apr-2002) Localised resource bundles for French, German and
632 Spanish languages (thanks to Anthony Boulestreau, Thomas Meier
633 and Hans-Jurgen Greiner for the translations). An area XY
634 plot and meter chart contributed by Hari. Symbol charts
635 contributed by Anthony Boulestreau. An improved
636 CandleStickRenderer class from Sylvain Vieujot. Updated
637 servlet code from Bryan Scott. XYItemRenderers now have a
638 change listener mechanism and therefore do not have to be
639 immutable. Additional demonstration applications for
640 individual chart types. Minor bug fixes.
641
6420.8.0 : (22-Mar-2002) All the category plots are now controlled
643 through the one class (CategoryPlot) with plug-in renderers.
644 Added a ResourceBundle for user interface items that require
645 localisation. Added a logarithmic axis class contributed by
646 Mike Duffy and some new JDBC and servlet code contributed by
647 Bryan Scott. Updated the JCommon class library to improve
648 handling of time periods in different time zones.
649
6500.7.4 : (6-Mar-2002) Bug fixes in the JCommon Class Library. Various
651 Javadoc comment updates. Some minor changes to the
652 code. Added new domain name (http://www.object-refinery.com)
653 in the source headers.
654
6550.7.3 : (14-Feb-2002) Bug fixes.
656
6570.7.2 : (8-Feb-2002) Integrated the WindPlot code from Achilleus
658 Mantzios. Added an optional background image for the
659 JFreeChart class, and another optional background image for
660 the Plot class. Added alpha-transparency for the plot
661 foreground and background. Added new pie chart label types
662 that show values. Fixed a bug with the legend that results in
663 a loop at small chart sizes. Added some tooltip methods that
664 were missing from the previous version. Changed the Insets
665 class on chart titles to a new Spacer class that will allow
666 for relative or absolute insets (the plan is to eventually
667 replace all Insets in the JFreeChart classes). Fixed a bug in
668 the setAutoRangeIncludesZero method of the NumberAxis class.
669 Added the instructions that were missing from the copies of
670 the GNU Lesser General Public Licence included with JFreeChart.
671
6720.7.1 : (25-Jan-2002) Added tooltips, crosshairs and zooming
673 functions, thanks to Jonathan Nash and Hans-Jurgen Greiner
674 for contributing the code that these features are based on.
675 Moved the combination charts into the package
676 com.jrefinery.chart.combination, made a number of other small
677 API changes and fixed some bugs. Removed the Javadoc HTML
678 from the download to save space (you can regenerate it from
679 the source code if you need it).
680
6810.7.0 : (11-Dec-2001) New combination plots developed by Bill
682 Kelemen. Added Wolfgang Irler's servlet demo to the standard
683 download. The About window in the demo application now
684 includes a list of developers that have contributed to the
685 project.
686

688 charts and 3D bar charts. Improved pie chart. Data
689 interfaces and classes moved to the JCommon class library.
690 New properties to control spacing on bar charts. New
691 auto-tick mechanism. JFreeChartPanel now incorporates
692 buffering, and popup menu. Javadocs revised. Fixed numerous
693 bugs from version 0.5.6. Demo application updated.
