Combined Category Plot Example using JFreeChart

     

This Example shows you how to create a Combined Category Plot chart using JFreeChart. Code for the chart shows runs of two team in a match.

In the code given below we have extended class ApplicationFrame to create a frame and also pass a string value to the constructor of ApplicationFrame class by using super keyword that will be name of the created frame.

The method used in this example are described below:

pack(): This method invokes the layout manager.

centerFrameOnScreen(): This method is used for the position of the frame in the middle of the screen.

setVisible(): This method is used for display frame on the screen.

addValue(): This method is used for add data into DefaultCategoryDataset class object according to the category.

JFreeChart: JFreeChart class object is used to create new chart according CategoryPlot class object

setBackgroundPaint(): This method is used to set the paint used to fill the chart background.
