I'm trying to build an histogram which must count only the first occurrences (chronologically speaking) of all recorded events for the corresponding period (in my data, a specific event can occur several times with a different outcome each time). From what I gathered so far, this might be done by using data aggregations.
However, I'm having trouble finding examples in Kibana on how to give an aggregation as in input to filter the elements being counted...
I'm not sure that I have been clear enough, do not hesitate to ask for further info.
Thanks in advance everybody
