barchart display labels

[madhuri_ls]

Hi

i am using JSP to display. How to display value labels on each bar??

Code:-

CategoryAxis categoryAxis = new CategoryAxis("Student Test - 1");
categoryAxis.setCategoryMargin(0.3);
categoryAxis.setVerticalCategoryLabels(true);
ValueAxis valueAxis = new NumberAxis("Questions");
BarRenderer renderer = new BarRenderer();

renderer.setToolTipGenerator(new StandardCategoryToolTipGenerator());
renderer.setItemMargin(0);
renderer.setMaxBarWidth(4.0D);
renderer.setDrawBarOutline(false);

renderer.setItemLabelsVisible(true);
CategoryPlot plot = new CategoryPlot(dataset, categoryAxis, valueAxis, renderer);
JFreeChart chart = new JFreeChart("", JFreeChart.DEFAULT_TITLE_FONT, plot, true);
chart.setBackgroundPaint(java.awt.Color.white);

// Write the chart image to the temporary directory
ChartRenderingInfo info = new ChartRenderingInfo(new StandardEntityCollection());
filename = ServletUtilities.saveChartAsPNG(chart, 500, 300, info, session);

// Write the image map to the PrintWriter
ChartUtilities.writeImageMap(pw, filename, info);
pw.flush();


Thanks
