Charts are normally used to display output data. However, it is also
possible to use a chart for graphically create input data. A quick example
is the way that GEF elements can be created from a panel, they can be
moved and modified in size , and finally they can be deleted.
Here is the question: what is the optimal way to implement the GEF style
elements in BIRT charts?
The examples for interactivity do not include anything for moving elements.

Thanks, I see what you mean. There is no way to do this now, in fact it
seems a different product altogether. I imagine it can be implemented in GEF
to create static charts. The real challenge would be to map those GEF
figures to a BIRT Chart model, that seems quite difficult to render exactly
the same thing using the chart engine and Draw2D Figures.
Thanks,
David
