    <p>In iReport 3.7.6 you can just check "Show Labels" box under BarPlot properties. </p> <p>In a prior version (3.1.4), I had to create a ChartCustomizer class.</p> <p>If you need to format the number in the label (e.g. to Percentage, add thousands separator, etc), then you definitely need a ChartCustomizer, even in the new version.</p> <p>A simple example: </p> <pre><code>import java.text.NumberFormat; import net.sf.jasperreports.engine.JRChart; import net.sf.jasperreports.engine.JRChartCustomizer; import org.jfree.chart.JFreeChart; import org.jfree.chart.labels.AbstractCategoryItemLabelGenerator; import org.jfree.chart.labels.CategoryItemLabelGenerator; import org.jfree.chart.plot.CategoryPlot; import org.jfree.chart.renderer.category.BarRenderer; import org.jfree.chart.renderer.category.CategoryItemRenderer; import org.jfree.data.category.CategoryDataset; public class SimpleBarChartCustomizer implements JRChartCustomizer { public void customize(JFreeChart chart, JRChart jasperChart) { CategoryPlot plot = chart.getCategoryPlot(); BarRenderer renderer = (BarRenderer) plot.getRenderer(); CategoryItemRenderer catRenderer = ((CategoryItemRenderer)renderer); catRenderer.setBaseItemLabelGenerator(new NumberLabelGenerator("", NumberFormat.getInstance())); } static class NumberLabelGenerator extends AbstractCategoryItemLabelGenerator implements CategoryItemLabelGenerator { public NumberLabelGenerator(String labelFormat, NumberFormat formatter, NumberFormat percentFormatter) { super(labelFormat, formatter, percentFormatter); } protected NumberLabelGenerator(String labelFormat, NumberFormat formatter) { super(labelFormat, formatter); } private NumberFormat formatter = NumberFormat.getInstance(); public String generateLabel(CategoryDataset dataset, int series, int category) { Number b = dataset.getValue(series, category); formatter.setMaximumFractionDigits(2); return formatter.format(b); } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
