+1 for releasing new version

+1 for adding the checks to JFreeChart if calls are made on JavaFX thread

I tried to implement the function myself.
See https://github.com/jfree/jfreechart/pull/6

OK, I found how to do it. The trick is that one JFreeChart can be added to both ChartViewer (JavaFX) and ChartPanel (Swing) at the same time. Printing via AWT using the following code creates a nice, sharp output: SwingUtilities.invokeLater(() -> { PrinterJob job = PrinterJob.getPrinterJob(); PageFo...

Using AWT might be the best approach, until the printing support in JavaFX gets some improvements.

I am not sure, though, how to obtain the AWT Printable from the JavaFX ChartViewer.

I tried that approach. The Scale transformation increases the size of the image, but not the resolution. The final image is very pixelated.

When ChartVIewer is printed using standard JavaFX printing tool PrinterJob.printPage(node), the resulting image is very poor (low resolution). In contrast, printing from the Swing JFreeChart is very sharp. The issue is probably related to printing the contents of a Canvas (see e.g., http://stackover...

Hi, I am using JFreeChart with XYPlot with a NumberAxis on both X and Y axes. Using the JavaFX ChartViewer, when I click on the Y axis it seems to do full zoom out (set auto range to both axes). Clicking on the X axis has no effect. AFAIK clicking on any axis had no effect in the Swing version. I th...

Hi David, Since you are now preparing the new version of JFreeChart, I have a suggestion for a minor improvement. Zooming with mouse is very intuitive with JFreeChart - just select the area and it zooms in immediately. However, I noticed many users struggle to find the way to zoom out - they do not ...

If it becomes a Canvas extension, please keep the contextMenu property (as a JavaFX property), so the context menu can be defined it FXML.

Amazing!
JFreeChart never stops surprising me

Hi, We noticed that if JFreeChart line chart is drawn into a vector device such as PDF, the plots are composed of many disconnected lines. This is ok for screen viewing, but when a vector graphics file (e.g., PDF or SVG) is produced, it makes subsequent downstream editing more difficult, because it ...

I guess ChartViewer extending Control makes some sense, because Control is for components that the user interacts with, while Canvas is for plain drawing.
JFreeChart seems more like Control to me, because it has zooming, context menus, tooltips, etc.

Why not remove ChartCanvas and put everything into ChartViewer, for the sake of backwards compatibility?

In a related comment, it seems there used to be an option to enable/disable domain/range axis mouse-wheel zooming, but that option is not present in the JavaFX ChartViewer.
