I have a charting question and would love some guidance and thoughts on this problem.
I'm looking for a good way to allow users to select aggregate numbers for all datapoints, but also allow the granularity of looking at one at a time or comparing them to each other. See: http://bit.ly/yQf28o , also attached.
If you've seen best practices or patterns being used for this case, please point me to it. Much appreciated, thank you all!
