We're using Event Tracking to keep track of interactions with rich native advertising units. Events are fired any time a page containing the unit is loaded (to determine denominator for interaction %).
An event is also fired whenever an element within the unit is hovered-over by the user. The event category captures the name of the product, the event label the URL and the action the index of the element hovered-over. The event value is the time in seconds the unit was open for.
What I need is to get a more sophisticated view of the event value than sum and average. Ideally, I'd be able to look at a histogram to show the distribution of interaction times, or see the total interaction time for a given user in all elements in the unit.
It seems there's no way to get at this info within GA or a customized view, but would this be possible with the GA reporting API?
