jFreeChart: Setting different positive and negative standard deviations on a bar chart

Question

Hello!

I need to create a StatisticalBarChart that not just has one value for standard deviation but a positive and negative standard deviation. So that the deviation is not symmetrical around the mean value. This is how it's supposed to look:

Any ideas? Thanks in advance!

You'll have to extend BarRenderer to override drawItem() and extend AbstractDataset to provide the extra data, as suggested in the PLSNPAIRS classes, AsymmetricStatisticalBarRenderer and AsymmetricStatisticalCategoryDataset.
