I have two fields in elastic search document, item_id, package_id, and creation_time. They are in a one to may relationship ( 1 item_id -> many package_id)
I want to display the (number of unique package_id/ unique number of item_id) in buckets based on creation_time.
Is this possible in kibana (version 5.5.1)? I am able to get the unique count of item_id and unique count of package_id and split them into buckets. I have no idea how to divide them (items/packages). Please help.
