BarChart IntervalXYDataset: Labeling the bars with value?

[talentfree]

I've another question on BarCharts.
I use an IntervalXYDataset and trying to write the values of the bars somewhere, above or inside of the bar. I found some help, but only with different datasets and the function to turn on the labeling was bound to the dataset...
My code is still like in my other thread: Bar-Color depending on the value.

Can I please get another push in the right direction?
Thanks!

Have you tried IntervalXYItemLabelGenerator?

That one works now, thanks. I tried XYItemLabelGenerator, which didn't work out.
