        JFreeChart chart1;
        DefaultCategoryDataset dataset = new DefaultCategoryDataset();
        dataset.setValue( 5, "Value", "Kobe Bryant" );
        dataset.setValue( 6, "Profit", "Kobe Bryant" );
        dataset.setValue( 9, "Value", "Paolo Maldini" );
        dataset.setValue( 7, "Profit", "Paolo Maldini" );
        dataset.setValue( 10, "Value", "Thierry Henry" );
        dataset.setValue( 8, "Profit", "Thierry Henry" );
        dataset.setValue( 9, "Value", "Maradona" );
        dataset.setValue( 5, "Profit", "Maradona" );
        dataset.setValue( 3, "Value", "Beckham" );
        dataset.setValue( 12, "Profit", "Beckham" );
