Hi,
I am using JFreeChart for displaying dynamic charts in a java application, and also using Hibernate as a backend to store and retrieve data from database.
To display database data on charts, obviously hibernate is required.
Can I use hibernate to display data on charts ?

Thanks...

Sure - I do all the time (in a web application but the basic process is the same).
Firstly, that are two different tools in the pipeline.
(a) Hibernate to collect the data (then possible post collection manipulation)
(b) the data is then passed to code which define the graph and the constraints.
(c) JFreeChart renders the chart

I suggest you get the chart to work with some fixed hard coded data set first then create the dataset dynamically via hibernate queries.
