Combine different log events in one data table

@bab

This would requires support for a bucket script in Kibana data-tables, which there is not now https://github.com/elastic/kibana/issues/4707

You could run this query manually too in dev-tools.

This would be an example of how to do it:

  • top-level term-aggregation on tradeReference
  • min sub aggregation to get minimum date
  • max sub-aggregation to get maximum date
  • bucket sub-aggregation to subtract max from min
