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.

34-----------------
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.
107

1095.  SUPPORT
110-----------
111Support questions can be posted in the free support forum at
112
113    http://www.jfree.org/phpBB2/viewforum.php?f=3
114    
115We read all questions posted in the forum, and respond to as many as we can
116in the time available.  Unfortunately, there are too many questions to answer
117them all.
118    
119If you need commercial support for JFreeChart, this is offered by
120Object Refinery Limited:

123
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
132    http://ant.apache.org/
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.

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);
429        - Barak Naveh has contributed new classes MatrixSeries and
430          MatrixSeriesCollection, along with demos:  BubblyBubblesDemo.java
431          and BubblyBubblesDemo2.java;
432        - the TextTitle class now has a background paint attribute;
433        - the StandardLegend class now generates LegendEntity objects if a
434          ChartRenderingInfo instance is supplied to the draw(...) method;
435        - extended the CategoryTextAnnotation class to take into account a
436          category anchor point.  See the SurveyResultsDemo.java application
437          for an example;
438        - included numerous bug fixes;
439
4400.9.8 : (24-Apr-2003)
441        - changed package naming from com.jrefinery.* to org.jfree.*;
442        - added new TimePeriodValuesCollection class;
443        - added MIME type code to ServletUtilities class;
444        - reversed the order of PieDataset and KeyedValuesDataset in 
445          the class hierarchy;
446        - reversed the order of CategoryDataset and KeyedValues2DDataset
447          in the class hierarchy;
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
464          Klaus Rheinwald;
465
466        Bug fixes:
467        - added a workaround for JVM crash (a JDK bug) in pie charts
468          with small sections (see bug report 620031);
469        - fixed minor bug in HorizontalCategoryPlot constructor (see
470          bug report 702248);
471        - added code to ensure HorizontalNumberAxis3D is not drawn if
472          it is not visible (see bug report 702466);
473        - added small fix for suppressed chart change events (see bug
474          report 690865);
475        - added pieIndex parameter to tooltip and URL generators for
476          pie charts;
477        - fixed bug in getLastMillisecond() method for the Second
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;
492        - corrected error in Javadoc generation (Ant script);
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.
532        - ChartMouseEvent now includes source chart.
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
551
552        Fixed bugs and updated documentation.
553
554        API changes include:
555        - added tickMarkPaint to Axis constructor (also affects
556          subclasses);
557        - added getLegendItems() to Plot, and deprecated
558          getLegendItemLabels();
559        - added getLegendItem(int) to XYItemRenderer and
560          CategoryItemRenderer.
561        - most 'protected' member variables have been changed to
562          'private'.
563
5640.9.3 : (4-Sep-2002) Added multiple pie charts based on
565        CategoryDataset.  Updated logarithmic axes.  Improved URL
566        support for image map generation. Moved the com.jrefinery.data
567        package from JCommon to JFreeChart. Added simple framework for
568        chart annotations. Improved control over renderers. Duplicate
569        x-values now allowed in XYSeries. Optional category label
570        skipping in category axes. Added CategoriesPaint attribute to
571        AbstractCategoryItemRenderer.  Added new attributes to
572        MeterPlot class. Updated 3D pie chart to observe start angle
573        and direction, and also foreground alpha < 1.0. Improved
574        Javadoc comments. New demo applications, including:
575        AnnotationDemo1, EventFrequencyDemo, JDBCCategoryChartDemo,
576        JDBCPieChartDemo, JDBCXYChartDemo and MinMaxCategoryPlotDemo.
577        Bug fixes:
578        - negative percentages on PiePlot.
579        - added listener notification to setXXXAxis(...) methods.
580        - fixed DomainInfo method name clash.
581        - added DomainIsPointsInTime flag to TimeSeriesCollection to
582          give better control over auto range on axis for time series
583          charts.
584        - axis margins for date axes are no longer hard-coded.
585        - fix for ordering of categories in JdbcCategoryDataset.
586        - added check for null axis in mouse click handler.
587
588        The CVS repository at SourceForge has also been restructured
589        to match the distribution directory layout.
590
5910.9.2 : (28-Jun-2002) PiePlot now has startAngle and direction
592        attributes.  Added support for image map generation.  Added a
593        new Pie3DPlot class. Added label drawing code to bar
594        renderers. Added optional range markers to horizontal number
595        axis.  Added bar clipping to avoid PRExceptions in bar
596        charts.  JFreeChartDemo has been modified and now includes
597        examples of the dial and thermometer plots.
598        Bug fixes:
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;
606        - removed unnecessary imports;
607
6080.9.1 : (14-Jun-2002) Bug fixes and Javadoc updates.
609        - fixed auto range calculation for category plots;
610        - fixed event notification for XYPlot;
611        - fixed auto axis range for Gantt charts;
612        - check for null popup menu in ChartPanel.mouseDragged;
613        - new checks for null info in renderers;
614        - range markers now drawn only if in visible axis range;
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
6870.6.0 : (27-Nov-2001) New plots including scatter plot, stacked bar
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.
