Customize JfreeBarChart

A bar chart or bar graph is a chart with rectangular bars with lengths proportional to the values that they represent.We need charts to represent data in pictorial format so that it becomes more appealing.

We have chart options present palette but they have very limited customization properties available therefore we need customizer classes to represent graph in a better format.

In this article I will show how to customize chart both by using customization properties in ireport

and through customizer classes.

Now how to create charts:

1.) Drag chart from palette window into detail band or summary band depending upon requirements.

(I have used chart in summary band).

2.) From the Palette choose bar chart option.
