Java SE (Java Platform, Standard Edition)

Hi guys!

Currently I try to integrate a JavaFX BarChart into my existing Java application. Therefore I need a BufferedImage of my BarChart, so that I can render that snapshot on a Graphics instance.

I adapted the existing BarChartSample.java (Chart Sample | JavaFX Tutorials and Documentation) and removed all animations. The code itselfs works fine but I identified one problem -> my TickLabels are missing

The TickLabels are visible If I use JDK 1.7u51 but if I change to JDK 1.8u05.... than the stlye of my BarChart will be changed and my tick labels are not visible.

Did I missed something or is that a bug?

Thanks in advance!

Best Regards,

Steve
