-----------------
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:


org.jfree
jfreechart
1.0.19



org.jfree
jcommon
1.0.23


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

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'.

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:

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.

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

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

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.
