Hello,
We currently using Elastic stack 5.5.1. We are building a security dashboard and we would like to have a visualisation which can calculate the difference between MIN metric: @timestamp and MAX metric: @timestamp
so we can have the duration of a potential attack.
As it shows in the screenshot I have already min @timestamp marked as start of an attack, max of @timestamp marked as end of the attack, now I'd like to somehow be able to find how long the attack last (min-max) and have it in a dashboard.

@lefagr this isn't currently possible, the following [issue](https://github.com/elastic/kibana/issues/2805) discusses some other user's needs as well, please feel free to comment with your use-case.
