Stacked 3d Bar Chart Example using JFreeChart

This Example shows you how to create a Stacked 3d bar chart using JFreeChart. Bar chart will represent the score of two team in different matches.

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.

Some methods that are used in this code :
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.

createCategoryDataset(): This method is used to create the instance of CategoryDataset Interface and that contains a copy of the data in an array.

createStackedBarChart3D(): This method is used to create stacked bar chart for given values. It takes title, domain axis label, range axis label, dataset, Plot Orientation, legend, tool tips and urls as param eters.

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