This dashboard was meant as a proof-of-concept...that swing dashboards could be used without too much pain. I'd really like to write a more flexible one, but havent had the time.
If you would like to modify the dashboard, look at the source. The UI is pretty much entirely generated with the Netbeans UI builder(Eclipse's VEP didnt work on my Java EE build
) so i suggest that you open the project in netbeans and edit the Dashboard JPanel.
