JfreeChart1.5.0

JFreeChart ========== Version 1.5.0, 5 November 2017. [](https://maven-badges.herokuapp.com/maven-central/org.jfree/jfreechart) Overview -------- 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. Building JFreeChart ------------------- You can build JFreeChart using Maven by issuing the following command from the root directory of the project: mvn clean install The build requires JDK 1.6.0 or later. Migration from JFreeChart 1.0.x ------------------------------- When migrating from JFreeChart 1.0.x to JFreeChart 1.5.0, please be aware of the following API changes: * all the classes from JCommon that are used by JFreeChart have integrated within the JFreeChart jar file within a different package than before (you will need to change your imports); * many methods `getBaseXXX()/setBaseXXX()` have been renamed `setDefaultXXX()/getDefaultXXX()`; * the `ChartUtilities` class has been renamed `ChartUtils`; * all the classes relating to pseudo-3D charts have been removed, as much better 3D charts are offered by [Orson Charts](https://github.com/jfree/orson-charts) so we prefer not to maintain the pseudo-3D chart code within JFreeChart; * the `SegmentedTimeline` class has been removed due to being (a) complex, (b) not always being correct and, as a result, generating too many support requests; * the `org.jfree.chart.utils.ParamChecks` class has been renamed `org.jfree.chart.utils.Args`. Please refer to [Issue 66](https://github.com/jfree/jfreechart/issues/66) for additional info.
