I've given all my data 1 of 3 possible event types. In addition, each event has a field "foo" (which contains roughly 3 values).
What I want to do is....
-For each value in field foo
-count the number of occurrences for each event type
-Plot those counts over time.
I would expect that the resultant timechart would have ~3^3 lines with data points for each day.
How would I do this?
