How to wrap category labels in JfreeChart

问题:

I have Stacked Bar Chart created using JFreeChart. The labels of the category are quite big and they overlap with the label of the next Bar. I would like to wrap it to the next line. I did some searching and found that i have to use the below code. setMaximumCategoryLabelLines(2) in the CategoryAxis and still it doesn't wrap to the next line.

Please suggest solutions.

Altering the BarChartDemo1 code as shown and using long category names, I see the chart below. It seems to work with stacked rendering, too. Is that the desired effect?

private static JFreeChart createChart(CategoryDataset dataset) {
    ...
    // OPTIONAL CUSTOMISATION COMPLETED.
    domainAxis.setMaximumCategoryLabelLines(2);
    ...
}
