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:

On the JFreeSVG home page:

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.

Fixed now, thanks for letting me know.

The item labels feature doesn't include any automatic way to avoid labels overlapping - sometimes there just isn't enough space. I would suggest that if you need to display data values for every single point in your chart, then perhaps you should just present the data in a table, maybe with a chart ...

How is the source series defined? I think there might be a mismatch between the RegularTimePeriod instance used internally by the TimeSeries and the periodCount argument you are using in the call to the method creating the moving average, but it is hard to tell.

This renderer uses a single color in order to maximise performance - once you start changing the color for each data item, you'll have to bear the cost of that state change.
