Hi:

I have a set of data, going across by months, and going down into different
categories that I have to graph using stacked column charts. Since the data
is going to be in the same columns, just going down a category...I'd like to
know if there is a way for me to add some kind of drop-down to the chart so
that users can just drop-down to CATEGORY 1, and see the chart for CATEGORY
1, without me having to build 10 different charts that i'll have to update
everytime i add new data.

I would appreciate any advice or feedback.
