Add an Image next to a X-axis label on a JFreeChart's barchart

I have requirement for the barchart which I have created using JFreeChart libraries.

I am illustrating this using an example. Lets say: I have plotted "John", "Mark", "Louis" and "Keith" on the X-axis (Students) and their respective marks on the Y-axis. I am using three different bars for each of the students to show their respective English, Science, and Maths marks.

Lets say, Science weigh the most, hence a student getting highest in Science would get a "Gold-Medal". Highest in "Maths" would fetch a student a "Silver", and highest in English would fetch him a "Bronze"

I want to put a small image (gold, silve or bronze) beside the label of the student who has got the highest marks in each of the subjects. A particular student (obviously) can get all the medals. Can this (or a thing similar to this) be done.

I am using JFreeChart's ChartFactory.createBarChart(...) api for this. I am able to plot the graph correctly but stuck with the above requirement.

Thank you!

It has been a long time this question was asked,

This is what I have done to achieve it.

Drawn a image at  : (x,y) at each Category Entity.
Size of image     :  (width ,height) of CategoryLabel entity.

You can place you image accordingly around the category label.

Hope it helps.

You might look at one of the org.jfree.chart.annotations such as XYDataImageAnnotation, XYDrawableAnnotation or XYImageAnnotation.
