How to put the data on the bar? on top the bar? I am newbie

[Pegasus]

The solution:

I was able to generate the bar labels at the top of each bar with the following code

Code:
renderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
renderer.setBaseItemLabelsVisible(true);
renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(ItemLabelAnchor.OUTSIDE12, TextAnchor.BASELINE_LEFT));
