Chartelligence is a framework for tracking real world events and correlating them with Analytics charts, in order to get real world answers to the ultimate question of "why" to your metrics.
Charts give you an answer to "how" or "what" your metrics are doing in a glimpse, but the fail to provide the "why". Why the sudden peak in traffic? Why the dive in sales? Why is conversion rate acting up?
Chartelligence overlays events data layers right on top of your charts, so you get answers right away.
