Custom label for bar chart-Using CategoryItemLabelGenerator?

[rahul]

Hi,
I have a bar chart on which I want to display a date below each bar on the X -axis. I got to know that CategoryItemLabelGenerator is to be used. But I am not able to understand how to do that. Can somebody please help me??

No, the x-axis labels in a CategoryPlot are derived by JFreeChart calling the toString() method on the objects you are using for the column keys in your dataset. These keys can be any instance of Comparable (for example, the String class). If you use the String class, then obviously the toString() method returns the string itself, so the label is the same as the key. But you could just as easily implement your own CustomCategory class that implements Comparable (so can be used as a key in the dataset) *and* overrides the toString() method to return whatever label you want.

Thanks.
