Hi Thamizh & David - Yes, sorry I meant: Dynamic for a "SUM" or "COUNT" of a specific set of items. In other words, the requirement is similar to what you mentioned, which is an Aggregate Bar Chart / Pivot Chart for items.
The hack http://people.csail.mit.edu/karger/Exhibit/Nobelists/nobelists.html is a static bar chart of an aggregate, vs the dynamic visualization I'm looking for. Is there enough interest on this to flush out how to get this implemented?
