I would like to count the events per week but first filter the events for every day on the last event. So basically also if there have been 20 events for one day it should only be counted once for the week. I thought I could make the first aggregation (filtering the last event per day) with the JSON Input field. And the create a bar chart which counts the results aggregated by week.
But I am really not familiarized with the use of JSON input. Can somebody help me? Or is that not supported with JSON input?
