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:

FXGraphics2D 2.0 has been released. It is now a first-class Java module and requires Java 11 or later. From the README file: 27-Feb-2020 : Version 2.0 - converted to a module (org.jfree.fxgraphics2d); - now requires JDK 11 or later. FXGraphics2D is hosted at GitHub: https://github.com/jfree/fxgraphi...

JFreeSVG 4.0 has been released. It is now a first-class Java module and requires Java 11 or later. From the README file: Version 4.0 (27-February-2020) - created a module for JFreeSVG: `org.jfree.svg`; - increased the minimum required Java version to 11; - changed the Maven artifact ID to match the ...

That is a bit inconsistent, I guess because the original code was submitted by someone else and I never spotted it. I'll look and see what is required to fix it.

You can use the setTickLabelFont() method: plot.getDomainAxis().setTickLabelFont(new Font(Font.DIALOG, Font.BOLD, 6)); Just note in the demo that the line ChartUtils.applyCurrentTheme(chart); will override any formatting changes you make, so you should either adjust the theme, or make your changes a...

I see this also. What is happening is that the range for the axes is determined by looking at the minimum and maximum data values. In this case, there is just a single value (429.6) so JFreeChart has to decide what should be the minimum and maximum values on the axis. It does this by looking at an a...

No, there are breaking API changes. The README on the GitHub project page provides an overview of the main changes:

No, JFreeChart is more targeted at plotting numerical and time-series data.

The getSeriesStroke() method will not return null if the autoPopulateSeriesStroke flag is set to true, which I think is the default:

Which test fails? What are the results on newer JREs? Note that JCommon isn't used in the latest versions of JFreeChart, so another option would be to migrate to the latest release of JFreeChart.

I'm not sure of the version numbers you are referring to, but AbstractDataSource became AbstractDataset way back in the history of JFreeChart.
