-----------------
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.

deprecation, so code written against 0.9.10 should recompile.

0.9.10 : (25-Jul-2003) 
         - added support for multiple secondary axes, datasets and
           renderers;
         - minor feature enhancements and bug fixes;

0.9.9 : (10-Jul-2003) PLEASE NOTE THAT MAJOR CHANGES HAVE BEEN MADE IN THIS
RELEASE AND ONE OR TWO FEATURES MAY BE BROKEN.  PLEASE REPORT BUGS SO THEY CAN
BE FIXED FOR THE NEXT RELEASE.

        - 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;
        - there is now support for horizontal stacked 3D bar charts;
        - added support for range markers against secondary axis in a 
          CategoryPlot;
        - added labels to domain and range markers;
        - added a new HistogramDataset class (contributed by Jelai Wang) to
          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
          and BubblyBubblesDemo2.java;
        - the TextTitle class now has a background paint attribute;
        - the StandardLegend class now generates LegendEntity objects if a
          ChartRenderingInfo instance is supplied to the draw(...) method;
        - extended the CategoryTextAnnotation class to take into account a
          category anchor point.  See the SurveyResultsDemo.java application
          for an example;
        - included numerous bug fixes;

0.9.8 : (24-Apr-2003)
        - changed package naming from com.jrefinery.* to org.jfree.*;
        - added new TimePeriodValuesCollection class;
        - added MIME type code to ServletUtilities class;
        - reversed the order of PieDataset and KeyedValuesDataset in 
          the class hierarchy;
        - reversed the order of CategoryDataset and KeyedValues2DDataset
          in the class hierarchy;
        - minor bug fixes;

0.9.7 : (11-Apr-2003) 
        - added a new ValueDataset interface and DefaultValueDataset
          class, and changed the CompassPlot class to use this instead
          of MeterDataset;
        - added DataUtilities class, to support creation of Pareto
          charts (new demo included);
        - updated writeImageMap method as suggested by Xavier Poinsard
          (see Feature Request 688079);
        - implemented Serializable for most classes (this is likely to
          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);
        - fixed minor bug in HorizontalCategoryPlot constructor (see
          bug report 702248);
        - added code to ensure HorizontalNumberAxis3D is not drawn if
          it is not visible (see bug report 702466);
        - added small fix for suppressed chart change events (see bug
          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;

0.9.6 : (17-Feb-2003) Bug fixes:
        - 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.
        - fixed null pointer exception in StackedVerticalBarRenderer3D;
        - Added get/set methods for min/max chart drawing dimensions
          in ChartPanel;
        - HorizontalIntervalBarRenderer now handles single category;
        - verticalTickLabels now possible in HorizontalNumberAxis3D;
        - removed unnecessary imports;

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.
