Java – JFreeChart Bar Graph Labels

javajfreechart

I have made it possible for value labels to appear on top of the bar in JFreeChart. However, it would look better if the labels are inside the bars. How do I make this work? The image below shows what I wanted the graph to look like.

Bar Graph with Label inside bar

I used the following code to make it work:

StackedBarRenderer renderer = new StackedBarRenderer(false);
renderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
renderer.setBaseItemLabelsVisible(true);
chart.getCategoryPlot().setRenderer(renderer);`

An XYItemLabelGenerator works well. If the standard one, discussed here, is not sufficient, you can always override generateLabel() to access your Map.

Addendum: In outline, your generator would look something like this:

private static class MyGenerator implements XYItemLabelGenerator {

    @Override
    public String generateLabel(XYDataset dataset, int series, int item) {
        return "Series " + series + " Item " + item;
    }
}

And you would install it in your renderer as shown in the example.

You should take a look at ItemLabelPosition, as explained here.

It is a property on the BarRenderer for the given chart. Try experimenting with the different values for the desired result.
