how to display customized values on a bar in bar chart using jfree chart?

Question

By using StandardCategoryItemLabelGenerator() Iam able to display the exact range axis value on a bar, Now my problem is I dont want to display the range axis value instead

Answer 1

renderer.setBaseItemLabelGenerator(
new StandardCategoryItemLabelGenerator()
 @Override
 public String generateLabel(CategoryDataset dataset, int row, int column) {
        return "Your Text" +row+","+column;
 }
);

Answer 2

StandardCategoryItemLabelGenerator uses an instance of MessgeFormat for this, defaulting to ArgumentIndex {2}. The other ArgumentIndex values are defined in the abstract parent. For example,

renderer.setBaseItemLabelGenerator(
    new StandardCategoryItemLabelGenerator(
        "{0} {1} {2} {3}", NumberFormat.getInstance()));
renderer.setBaseItemLabelsVisible(true);

You can also override generateLabel() to return any value you want.
