Hello,

Yes, Orson Charts is still maintained (Orson Charts 2.0 was released in 2020). See the GitHub page:

https://github.com/jfree/orson-charts

Commercial licenses are still available. I think I missed your first email, but responded last week with a copy of the license for your review.

There's some step-by-step instructions here: https://jfree.github.io/jfreechart-and-opencsv/ And also the JFreeChart Developer Guide is useful for getting started - we sell that to support the project, it comes with source code for all the JFreeChart demos as well (you can run the demos by downloadi...

The BarRenderer3D class (in older versions of JFreeChart) has the following constructor where you can set the offsets for the 3D effect: public BarRenderer3D(double xOffset, double yOffset) But you should note that these "3D" renderers have been removed from JFreeChart in more recent releases - you ...

JFreeChart 1.5.2 is now available to download: https://github.com/jfree/jfreechart/releases/tag/v1.5.2 Version 1.5.2 (31 December 2020) - observe series visibility flag in ClusteredXYBarRenderer (#89); - apply rendering hints to overlays (#187); - don't draw disabled outlines on crosshair labels (#1...

If you add an observation to the time series with a null value, this will cause the line to be interrupted as you require it.

Here is a sample - you would probably want to add some code to compute the string bounds and align the text accordingly, but the hard-coded positions here worked OK for me: public static void main(String[] args) throws IOException { SVGGraphics2D g2 = new SVGGraphics2D(200, 200); g2.setPaint(Color.R...

Yes, in fact JFreeSVG is able to create SVG output for anything you can "draw" via Java's Graphics2D API. It's not limited to charts. When I get time I'll post a small sample program.

Thanks for the report. I committed the fix this morning - it will be included in the next release (1.5.2).

To be honest, the Gantt chart support in JFreeChart is pretty basic. If you need something more industrial strength, I can recommend the libraries from DLSC:

I was just trying this out, and I don't get any issue in Chrome, Safari or Firefox on a Mac. Which browser gives you the font not found error? Or is it some other SVG viewer?

Thanks for the report - I opened a bug here:
