Create a dual axis chart using JFreeChart

This Example shows you how to create a dual axis chart using JFreeChart. Code given below creates a simple dual axis chart for 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.

Methods 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 to add values in DefaultCategoryDataset class object.
