We love that we can summarize data using charts. However, we need the ability to be able to click down on a pie slice or bar to see the detail of the records that make up that chart element. Right now, we change the visualization from a chart to a list, then filter to get the right info which is really inconvenient. We would have a much more powerful case for adoption, if we had this one click ability.
This would also be helpful from a summarized pivot, too :)
