I am trying to filter the kibana visualization here, and I want the chart to display only when the number of processes are more than two. My theory is that every process should have a unique hash, so if any hash has two different processes, then only it should display. The inside pie is the hash and the outer one is the process. I tried using min\_doc\_count:2, but the the issue is it display when there are more than 2 doc count, whereas what I want is it to display where there is more than 2 unique count of docs. Help appreciated 😃

this is unfortunately not possible at the moment, as kibana does not yet support bucket selector pipeline aggregation.
