The Gantt Chart in the current Chart implementation based on JFreeChart engine is more a "read only" concept. You provide data to the JFreeChart engine and the engine render the data into an image and pass that back to browser and show it as an "image".

If you need "interactive" operation such as "drag and drop" etc on the Gantt Chart. theoretically, it must be done separately using canvas. We have done some experiment on that and hopefully we can have a more "interactive" chart in the future.
