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

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 an comments, suggestions or bugs to report, please post a
message in the JFreeChart forum.

-----------------
3.  DOCUMENTATION
-----------------
You can download installation instructions
(jfreechart-1.0.13-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 <NAME> (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 1.0.15) 
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.

Previously we offered commercial support options, but this has been 
discontinued as there wasn't sufficient uptake to meet the cost of 
providing this service.

--------------------
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-1.0.13-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.

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.

Priority support is offered (in a separate forum at www.object-refinery.com) to
companies and institutions that have purchased a site licence for the
JFreeChart Developer Guide.

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.

A demo application that shows a selection of the charts that can be

      is not a good format for charts in any case, and it is usually better to 
      use PNG format;
    - copying charts to the clipboard (supported by the ChartPanel class) will
      not work if you are running on a very old version of the Java runtime
      (version 1.3.1).
    
If there are other items that you think should be listed here,
please post a bug report.
