JFreeChart Example(Area Chart)

import javax.swing.JFrame;

import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.CategoryDataset;
import org.jfree.data.category.DefaultCategoryDataset;

public class JFreeChartAreaChartExample extends JFrame {

    private static final long serialVersionUID = 1L;

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

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

	// Adding chart into a chart panel
	ChartPanel chartPanel = new ChartPanel(chart);

	// settind default size
	chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));

	// add to contentPane
	setContentPane(chartPanel);
    }

    private CategoryDataset createDataset() {

	// row keys...
	final String chrome = "Chrome";
	final String firefox = "Firefox";
	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(5.0, chrome, speed);
	dataset.addValue(7.0, chrome, popular);
	dataset.addValue(6.0, chrome, response);
	dataset.addValue(6.0, chrome, osindependent);
	dataset.addValue(7.0, chrome, features);

	dataset.addValue(4.0, firefox, speed);
	dataset.addValue(6.0, firefox, popular);
	dataset.addValue(5.0, firefox, response);
	dataset.addValue(5.0, firefox, osindependent);
	dataset.addValue(6.0, firefox, features);
	
	dataset.addValue(3.0, iexplorer, speed);
	dataset.addValue(4.0, iexplorer, popular);
	dataset.addValue(4.0, iexplorer, response);
	dataset.addValue(1.0, iexplorer, osindependent);
	dataset.addValue(5.0, iexplorer, features);

	return dataset;

    }

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

Output
