-----------------

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.

JFreeChart is licensed under the terms of the GNU Lesser General

Public Licence (LGPL). A copy of the <a href="about_files/licence-LGPL.txt">licence</a> 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-1.0.17-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 the previous release of JFreeChart

worked with JRE/JDK 1.4.2 or later.  With a bit of hacking, it may be possible

to get JFreeChart working on these older versions, but we are no longer

supporting it.

(b)  JCommon - version 1.0.0 or later.  The runtime jar file (version 1.0.21)

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.  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-1.0.17-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 not free, licenses can be purchased from Object Refinery Limited.

An additional tab added to the demo application in version 1.0.17 showcases

Orson Charts 3D, a new library by Object Refinery Limited.  You can find out

more about Orson Charts at:

    http://www.object-refinery.com/orsoncharts/

---------------

8.  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.

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 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);

        - added new CategoryTextAnnotation and XYLineAnnotation

          classes;

        - added new HorizontalCategoryAxis3D class contributed by

          Klaus Rheinwald;

          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;

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.

0.8.0.1 : (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.

0.8.0.0 : (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.

---------------

4.  WHAT'S NEW

---------------

Changes in each version are listed here:

1.0.21: (24-Oct-2013) Modified drawRotatedString() to call drawAlignedString()

                      when the rotation angle is 0.0.  This provides benefits

                      downstream for JFreeChart, JFreeSVG and OrsonPDF.

1.0.20: (01-Sep-2013) Fixed TextFragment.draw() to respect TextAnchor argument.

1.0.19: (30-Aug-2013) Updated Licences.java so that complete licence text is

                      loaded on demand only (bug #1118).

1.0.18: (23-Sep-2012) Fixed PaintList.equals() bug, fixed line break issue in

                      TextUtilities;

                      Composite instances;

1.0.16: (17-Apr-2009) New release in conjunction with JFreeChart 1.0.13;

1.0.15: (19-Dec-2008) New ResourceBundleWrapper class to enable applets to

                      bypass codeBase lookup.  Updated Maven specs.

1.0.14: (10-Sep-2008) Workaround added to PngEncoder, bug fix in ShapeList.

1.0.13: (05-Jun-2008) Bug fixes for TextBox and ShapeUtilities.

1.0.12: (02-Nov-2007) Made the resource-loading and classloader selection more

        robust in cases where the jars were distributed over several

        classloaders.

1.0.11: (19-Oct-2007) BugFix in the KeyedComboBoxModel causing

        NullPointerExceptions on MacOS-X; Make sure that all resource-streams

        that get opened also get safely closed in case of errors.

1.0.10: (21-May-2007) BugFix in the PackageSorter, Window positioning is now

        multi-screen aware.

1.0.9 : (23-Mar-2007) Serialization fix in TextFragment.

1.0.8.0 : (11-Dec-2006) Minor bugfixes in the synchronization of the Booting code

        and the FastStack.

1.0.7 : (03-Dec-2006) Cosmetic fixes for the logging of the PackageManager,

        ObjectTable implementation allows faster cloning of its contents,

        minor improvements to the GUI classes.

1.0.6 : (26-Sep-2006) BugFixes in the TextLayoutUtilities, SpreadSheetDate and

        ResourceBundleSupport classes.

1.0.5 : (29-Jun-2006) BugFixes in the boot code (synchronization added) and

        WaitingImageObserver (possible deadlock fixed). ObjectUtilities

                did not handle all cases where a ClassLoader could be null.

1.0.4 : (30-Apr-2006) Date- and NumberCellRenderer did not handle null-values

        properly.

1.0.3 : (17-Apr-2006) More improvements in the boot process for dependent

        library hierarchies.

1.0.1 : (10-Feb-2006) This release adds new boot capabilities and fixes

        some bugs in the XML classes. This version is required for

        JFreeReport and it is fully backward compatible with the 1.0.x

        branch.

1.0.0 : (14-Nov-2005) This is the official 1.0.0 release.  All future

        releases in the 1.0.x series will maintain backward compatibility

        with the 1.0.0 API.

1.0.0-rc1 : (01-Jun-2005) : Update to coincide with JFreeReport 0.8.0.5-5.

        JavaDoc update and classloader handling changed.

1.0.0-pre3 : (15-Apr-2005) : Some minor changes in the ResourceBundleSupport

        to allow the explicit definition of a locale.

1.0.0-pre2 : (04-Mar-2005) : Update to coincide with JFreeReport 0.8.0.5.

        Separated the xml-support packages into an own jar file.

        JFreeChart does not use these classes (except in experimental

        non-release code). Therefore, JFreeChart needs both libs to

        build, but only the jcommon.jar library to run.

        The a more detailed list of changed please have a look at the

        CHANGELOG.txt file.

1.0.0-pre1 : (29-Nov-2004) : Update to coincide with JFreeChart 1.0.0-pre1.

0.9.7 : (13-Oct-2004) Update to join JFreeReport with latest JFreeChart.
