private static final long serialVersionUID = 1L;

  
public JFreeChartBarChartExample(String applicationTitle, String chartTitle) {
       
super(applicationTitle);

       
// based on the dataset we create the chart
       
JFreeChart pieChart = ChartFactory.createBarChart(chartTitle, "Category", "Score", createDataset(),PlotOrientation.VERTICAL, true, true, false);

       
// Adding chart into a chart panel
       
ChartPanel chartPanel = new ChartPanel(pieChart);
      
       
// settind default size
       
chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
      
       
// add to contentPane
       
setContentPane(chartPanel);
   
}
  
  
private CategoryDataset createDataset() {
     
     
// row keys...
     
final String firefox = "Firefox";
     
final String chrome = "Chrome";
     
final String iexplorer = "InternetExplorer";

     
// column keys...
     
final String speed = "Speed";
     
final String popular = "Popular";
     
final String response = "Response";
     
final String osindependent = "OS Independent";
     
final String features = "Features";

     
// create the dataset...
     
final DefaultCategoryDataset dataset = new DefaultCategoryDataset();

      dataset.addValue
(1.0, firefox, speed);
      dataset.addValue
(4.0, firefox, popular);
      dataset.addValue
(3.0, firefox, response);
      dataset.addValue
(5.0, firefox, osindependent);
      dataset.addValue
(5.0, firefox, features);

      dataset.addValue
(5.0, chrome, speed);
      dataset.addValue
(7.0, chrome, popular);
      dataset.addValue
(6.0, chrome, response);
      dataset.addValue

      dataset.addValue
(6.0, iexplorer, features);
     
     
return dataset;
     
 
}

  
public static void main(String[] args) {
     
JFreeChartBarChartExample chart = new JFreeChartBarChartExample("Browser Usage Statistics", "Which Browser are you using?");
      chart.pack
();
      chart.setVisible
(true);
