org.jfree.chart.renderer.category.StatisticalBarRenderer
A renderer that handles the drawing a bar plot where each bar has a mean value and a standard deviation line. The example shown here is generated by the StatisticalBarChartDemo1.java program included in the JFreeChart Demo Collection:

                    = new DefaultStatisticalCategoryDataset();
            dataset.add(1.0, 2.0, "S1", "C1");
            dataset.add(new Double(4.0), null, "S1", "C2");
            CategoryPlot plot = new CategoryPlot(dataset, 
                    new CategoryAxis("Category"), new NumberAxis("Value"), 
                    new StatisticalBarRenderer());
            JFreeChart chart = new JFreeChart(plot);
            /* BufferedImage image = */ chart.createBufferedImage(300, 200, 
                    null);
            success = true;
        }
