JavaFX Overlay

Postby rsalter » Sat Nov 04, 2017 5:03 pm

Is it possible to add a crosshair overlay to a chart displayed using the JavaFX ChartViewer component?
If not, is it anticipated?

What happens if you add a ChartPanel with overlay, for example, to a JFXPanel?

Yes it is possible, but with the so-far-unreleased code at GitHub. I am creating a new release of JFreeChart that has the JavaFX code stripped out (no JavaFX means that the code will compile with JDK1.6), then created a separate project that contains the JavaFX extensions:

https://github.com/jfree/jfreechart-fx

All publicly available demo programs have been moved to another project:

https://github.com/jfree/jfree-fxdemos

If you look in there, you'll see a demo CrosshairOverlayFXDemo1.java that demonstrates the feature you are looking for. The only complication for now is that you'll have to check out several projects from GitHub and build them yourself in order to get this working. Today is a rainy day, so maybe I'll get some releases out the door.
