A new version of JFreeSVG has been uploaded to the Maven Central Repository. From the README file: Version 3.4 (10 February 2019) - added attribute for font size units override; - added automatic module name (org.jfree.jfreesvg); - omit transformation if it is the identity transform; - fixed drawStr...

Use the latest version, JFreeChart is still compiling and running with Java 6. If you want JavaFX support, then you'll need Java 8.

No. You can use Batik to generate SVG output, although I would recommend JFreeSVG as a smaller, faster and simpler dependency.

I'm not actively supporting the SWT code for JFreeChart, but you'll find all the latest status in these projects at GitHub:

• https://github.com/jfree/jfreechart

• https://github.com/jfree/jfreechart-swt

• https://github.com/jfree/swtgraphics2d

Yes, I'm dealing with it whenever I have the time. Super annoying.

Are you using the LegendTitle class? It has a setSortOrder() method.

Unless you have a strong reason for wanting to use Batik, I would recommend JFreeSVG - it is a simpler dependency, much smaller jar file, and the code runs faster:

Version 1.7 has been released, this fixes a bug where multiple calls to the setClip() method caused font and color attributes to be lost. The code is available from the Maven Central Repository: <dependency> <groupId>org.jfree</groupId> <artifactId>fxgraphics2d</artifactId> <version>1.7</version> </...

I think all you need to add is: chartViewer.setPrefHeight(300); ...because the preferred width and height of the ChartViewer are defaulting to 0. You could also consider removing the VBox and second anchor pane, and add the ChartViewer directly to the first AnchorPane: tab.setContent(anchorPane); //...

I would take a look at SimpleHistogramDataset, it is a different dataset implementation that allows for updates.

At some point (I think version 1.0.14) I changed the getDataItem() method to return a clone of the object to make it harder for the XYSeries to have its data values changed without triggering a SeriesChangeEvent.

What is the exact error, because that message doesn't make a lot of sense. In any case, I would recommend updating to JFreeChart 1.0.19 or 1.5.0.

Better is to make the jump to JFreeChart 1.5.0, then you don't need JCommon at all. But if you must use JFreeChart 1.0.x, then you'll see the JCommon dependency in the pom.xml <dependency> <groupId>org.jfree</groupId> <artifactId>jcommon</artifactId> <version>1.0.24</version> </dependency>

It's possible there was a bug somewhere along the way. The latest version is working, you should try to upgrade to the latest version of JFreeChart or compare the XYSeries and DatasetUtilities classes between the two versions to see what has changed.
