Hi,

It seems there is no way to get a reference to ChartCanvas from the corresponding ChartViewer node. I need the reference to manipulate the mouse listeners, which are properties of the canvas, not of the ChartViewer.

Perhaps this is an easy thing to add to version 1.0.20?

That looks great, thanks.

Hi, Is it possible to use JFreeChart to produce a stacked (3D-like) plot of multiple line charts, such as shown below? https://i.imgsafe.org/b3174ed.png I imagine modifying the LineAndShapeRenderer might be the right starting direction. But I am worried about the zooming functions, axes, etc. Thanks...

Hi, Currently the ChartViewer node cannot be used in FXML. I think the only reason is because it does not have a constructor without arguments (when I extended the ChartViewer class and added a simple constructor without arguments, I could add my wrapper class into FXML and it works). By the way, th...

Yes, we can compile the javafx-enabled jar using ant, but it would be nice to have it in Maven Central so mavenized projects can directly add it as a dependency.

David, *please*.

Hi,

There has been no new release of JFreeChart since July 2014. Would it be possible to release an updated version including the JavaFX support classes, and deploy it in Maven Central? I think more and more people are working in JavaFX now, so it would be helpful.

Happy New Year!

Tomas

Thanks a lot!
Is this going to be uploaded also to Maven repository?

It seems version 1.0.16 is not available at the Maven Central, or am I missing something?
Best regards,
Tomas

Indeed it is useful. What I meant was that it is not useful for semantic analysis.
Annotations can be added to return values as well:
This way the IDE can keep track of what can be null and what cannot be null, saving a lot of time for the developer.

ParamChecks.nullNotPermitted() is good for internal control within JFreeChart, but it is not useful for JFreeChart users. On the other hand, adding @Nonnull annotations would allow the users to use these in their semantic analysis - e.g. getting IDE warnings where nulls are not properly checked etc....

Hi, I noticed the use of ParamChecks.nullNotPermitted() in the new JFreeChart code. Just wondering - wouldn't it be better to use annotations such as @NonNull, @Nullable etc for this purpose? Modern IDEs have pretty good support for semantic analysis using these annotations. (this is not a criticism...

Hi,

this bug is still not fixed in JFreeChart 1.0.5.

Hello, I'm using JFreeChart 1.0.1. I was often getting NullPointerExceptions when updating the XYSeries at the same time while the chart (XYPlot) was being drawn. When I changed the XYSeries.java source constructor from this.data = new java.util.ArrayList(); to this.data = Collections.synchronizedLi...
