@Sh3ldoris, Sorry for the initial confusing with the timelion.

Unfortunately Kibana doesn't fully support bucket\_script aggregations yet. Here is the issue to track: [https://github.com/elastic/kibana/issues/4707](https://github.com/elastic/kibana/issues/4707). But _something_ is possible with TSVB.

I found this example and _I think_ it should be possible in similar fashion to achieve your goal.

1. Create a scripted field or reinvest you documents and add additional fields like: `dotStart: boolean; dotTimeout: boolean`.
2. Use sum aggregation and them bucket script to subtract 2 sums. (Similar as described in [Weighted Average in a DataTable of Kibana](https://discuss.elastic.co/t/weighted-average-in-a-datatable-of-kibana/185909/2))

Maybe there is a simpler way, but, _I think_ suggested way should also work.
