Graph Interactivity Question [message #150151]

I've successfully created a simple bar graph using the graph API however
I'm having trouble intercepting the specific selected bar using the
ICallBackNotifier interface. I've interrogated all of the objects passed
into the callback(Object event, Object source, CallBackValue value)
method, but can't quite seem to be able to get a handle on the particular
bar the user selected. The entire series is available by accessing the
DataSet object (via the StructureSource.getSource() method) but I need to
know exactly which bar was selected. Any help would be much appreciated.

I think this should be fixed in the latest build, you should be able to get
a WrappedStructureSource containing both the datapoint and the series.

Thanks,

David

David, thanks for your reply.

I can see that I can now create a WrappedStructureSource object using the
StructureSource object that is passed into the callback() method, but I
don't see how to access the selected bar. Do you have a code snippet
showing how to properly use this?

Okay, so the problem was I was just using too old of a build. I'm not
sure when this functionality got commited to the repository but it seems
to work properly in nightly build (N20060403).
