Basically, I'd like users of the my Java application to be able to adjust the
SQL and styling of a chart within the eclipse IDE. Once they're happy with the
design, they would save the design/chart to file. My application would load
the design/chart via the BIRT runtime, resize appropriately and rendered chart
into an image (or another appropriate format) and displayed within the
application.
Is this possible?
Is there a better way of allow the user to adjust the charts?
Is there an easier way of achieving the same result?
I have found integration details in the BIRT2.2 FAQ. Does anyone know of any
other samples?
I hope that this makes sense.

Stuart,
You can use the chart API directly to bind data to a chart model (outside a
report). Since your app is report-based, I assume you just need to render
the report inside your application, maybe using an embedded browser? For
resizing it, you can edit the model with the DE API.
If you are interested in running the chart standalone separately from the
report, you won't be able to use all the ODA features, but you can invoke
the driver directly, get an sql.ResultSet and bind it to the chart. You also
need to customize the chart builder for you app, so you can run it outside a
report, there is an examples in the chart examples plugin. Then you can
render the chart in Swing or SWT directly, that's the added benefit, and
it's more lightweight than running the whole report.
Thanks,
David
