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.

For your second question, could it be that the renderer is not an instance of DefaultCategoryItemRenderer?

The first issue is cause by the drawing of the zero baseline for the domain axis - this is a vertical line drawn at the value 0 on the x-axis. You have this line in your code: xyp.setDomainZeroBaselineVisible(true); Remove it and the baseline won't be drawn anymore and that should solve your problem.

The correct file will be picked up automatically based on the default locale of the user's runtime Java Virtual Machine.

Try this one:

At first glance this appears to be a bug in JavaFX. Did you try running it on Java 9 for a comparison?

There isn't a general solution for this in JFreeChart. I don't know what might be possible within JasperReports.

First, please post the exact exception message you see. Second, perhaps try a more recent version of JFreeChart (1.0.14 is quite old).

Did you see the setUpperBound() method?

No, not in JFreeChart. But you can do this in Orson Charts, another chart library I wrote:

I guess the permissions on your dropbox don't allow others to access the image. Can you upload it somewhere else?
