Hi Friend,

Try the following code:

DefaultCategoryDataset dataset = new DefaultCategoryDataset();
dataset.setValue(80,"Marks","A");
dataset.setValue(90,"Marks","B");

dataset.setValue(85,"Marks","D");
dataset.setValue(99,"Marks","E");
dataset.setValue(68,"Marks","F");
JFreeChart chart = ChartFactory .createBarChart3D(
"Test",
"Name",
"Marks",
dataset,
PlotOrientation.VERTICAL,true, true, false);
try
{
ChartUtilities.saveChartAsJPEG(new File("C:/chart.jpg"), chart, 400, 300);
}
catch (IOException e)
{
System.out.println("Problem in creating chart.");
}
