hi @asp

You would use a scripted field for that.

My response here - to a similar question - has some links to resources to help you get started [Plot latency measure based on two time fields in an index](https://discuss.elastic.co/t/plot-latency-measure-based-on-two-time-fields-in-an-index/73244/2)
