You can get a count by hovering your mouse over the pie chart. Otherwise I'm not aware of a way to include that. I agree though, pretty primitive offering. The list off to the side of the chart isn't even sorted by count, which I figured was basic common sense. I think this might be improved in Workspaces, but it has its own set of problems that prevent us from using it :\
Thanks Erik, was just a little disappointing because it looked nice when I was making it in the console.
