Stein,
Currently BIRT charts can only be bound to one dataset. Although you
can combine many datasets into one using the joint dataset feature, I am
not sure that will help in this case. You can also use scripting to
setup a javascript array of x and y values that can be retrieved from
many datasets. This approach is a bit more complicated but can be done.
The only caveat is that you have to have the same number of x and y
values. If this is something you are interested in I can help with an
example.

Thx so much for the clear and elaborate answer Jason.
The capability I was looking for is essential for the charting part of my application, so I will for now try another charting package which meets that requirement. Unfortunately, that will "hurt" the integration to my data in the EMF datastore and other nice report & charting capabilities BIRT offer. Can´t win them all...

If you want an example of building a chart dataset from multiple report
datasets using script let me know.
