public class Area{
public static void main(String arg[]){
  DefaultCategoryDataset dataset = new DefaultCategoryDataset();
  dataset.addValue(4.0, "Science", "Rahul");
  dataset.addValue(3.0, "Maths", "Rahul");
  dataset.addValue(5.0, "Science", "Vinod");
  dataset.addValue(2.0,"Maths", "Vinod");
  dataset.addValue(3.0, "Science", "Prashant");
  dataset.addValue(5.0, "Maths", "Prashant");
  dataset.addValue(6.0, "Science", "Tapan");
  dataset.addValue(2.0, "Maths", "Tapan");
  dataset.addValue(3.0,"Science", "Santosh");
  dataset.addValue(5.0, "Maths", "Santosh");

    JFreeChart chart = ChartFactory.createAreaChart
   ("Comparison between Students Marks","Students", "Marks ",
    dataset, PlotOrientation.VERTICAL, true,true, false);
  CategoryPlot p = chart.getCategoryPlot(); 
  CategoryItemRenderer renderer = p.getRenderer();
  ChartFrame frame1=new ChartFrame("Area Chart",chart);
