Version 1.5.0, 5 November 2017.
JFreeChart is a comprehensive free chart library for the Java(tm) platform that can be used on the client-side (JavaFX and Swing) or the server side (with export to multiple formats including SVG, PNG and PDF).
The home page for the project is:
http://www.jfree.org/jfreechart
JFreeChart requires JDK 1.6.0 or later. If JavaFX support is required, you need to also include the JFreeChart-FX extensions:
https://github.com/jfree/jfreechart-fx
The library is licensed under the terms of the GNU Lesser General Public License (LGPL) version 2.1 or later.
You can build JFreeChart using Maven. The build requires JDK 1.6.0 or later.
Using Maven you can build JFreeChart using the following command (issued from the root directory of the project):
mvn clean install

SPECIAL NOTICE: There will be a birds-of-a-feather session for JFreeChart at this year's JavaOne conference in San Francisco. The session is scheduled for 6.45pm to 7.35pm on Wednesday 3 June.
This release contains:
- updates to the
ChartPanel
class to support copying charts to the clipboard, panning and mouse-wheel zooming, and an overlay mechanism that supports crosshairs; - enhancements to the auto-range calculation for axes, providing the ability to use subranges only and also to skip hidden series;
- updates for many of the
CategoryItemRenderer
implementations to ensure that they respect theseriesVisible
flags; - an improvement to the
TimeSeries
class so that it is no longer necessary to specify the time period type in the constructor; - a new
SamplingXYLineRenderer
for improving the performance of time series charts with large datasets; - the
XYSeries/XYSeriesCollection
classes now cache the minimum and maximum data values to improve the performance of charts with large datasets; - entities are now created for the chart, data area and axes, allowing mouse clicks to be detected for these regions;
- added a bar alignment factor to the
XYBarRenderer
class; - a new
errorIndicatorStroke
field for theStatisticalLineAndShapeRenderer
andXYErrorRenderer
classes; - added a new
HeatMapDataset
interface,DefaultHeatMapDataset
implementation, and aHeatMapUtilities
class to make it easier to create heat map charts; - there is a new flag to allow an
XYDataImageAnnotation
to be included in the automatic range calculation for the axes; - additional attributes in the
XYTextAnnotation
class; - added a
sampleFunction2DToSeries()
method to theDatasetUtilities
class; - some changes to the
ChartPanel
class that help to work around a regression in JRE 1.6.0_10 relating to drawing in XOR mode. Regarding this final point:- the default value for the
useBuffer
flag has changed to true, which means that all charts will, by default, be rendered into an off-screen image before being displayed in theChartPanel
; - the zoom rectangle is drawn using XOR mode only when the
useBuffer
flag has been set to false. For most usage, this should improve performance (but at the cost of using more memory for eachChartPanel
used in your application);
- the default value for the

In addition, a bug in the SlidingCategoryDataset
class has been fixed, the
correct outline paint is now used by GradientXYBarPainter
, a new method
has been added to the ImageMapUtilities
class to escape special characters
in Javascript strings to avoid problems with the OverLIB and DynamicDrive
tooltips, and there are some important fixes in the LogAxis
class.
This release passes 2110 JUnit tests (0 failures) on JRE 1.6.0_12.
This release adds
- support for minor tick marks;
- mapping datasets to more than one axis;
- an important fix for the
XYSeries
class (relating to theaddOrUpdate()
method); - plus numerous other bug fixes.
This release passes 1996 JUnit test (0 failures) on JRE 1.6.0_10.

http://www.rapid7.com/advisories/R7-0031.jsp
Note that the fix incorporated in the special JFreeChart 1.0.8a release was flawed in that it broke the URLs in the HTML image maps generated by JFreeChart. Further amendments have been made in this release to fix this problem.

In this release, some new (incomplete) classes have been included in the
org.jfree.experimental.*
namespace. These classes are not part of the
standard API, but are included for developers to experiment with and provide
feedback on. Hopefully in the future, refined versions of these classes will
be incorporated into the main library. PLEASE NOTE THAT THE API FOR THESE
CLASSES IS SUBJECT TO CHANGE.
This is primarily a bug fix release. In addition, there are some API adjustments (there should be no breakage of applications coded to the 1.0.0 API).

), plus accessor methods, that controls whether or not the base value for the bar is included in the range calculated by thefindRangeBounds()
method;BubbleXYItemLabelGenerator

method;XYPlot
: added a newgetAnnotations()
method;XYSeries
: theupdate(int, Number)
method has been deprecated and a new methodupdateByIndex(int, Number)
has been added;

overlaid charts). This means that renderers now share a single
DrawingSupplier by default, which simplifies the creation of
combined charts;

to a single ColorBar class that wraps a ValueAxis (may have broken
one or two things in the process);

pie charts;

class and the getFirstMillisecond() method for the Year
class (picked up in JUnit tests);

bug 703050;

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.
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
