I think what you desire may be difficult but I did just realize That you can use the Line method I described above and Get the comparative bar charts
Today Kibana visualizations works off a single date range then with an offset from that, it does not readily support Two separate date ranges overlaid.
Elasticsearch does have JDBC ODBC connectors so perhaps you could use another visualization tool such Tableau.
Also there is support for Vega visualizations but those require custom programming.
One thing really cool about Elastic is that you could actually go to kabana GitHub repository and open your feature request and it could be considered / no promises.
Unfortunately, I think that is all I have for you...
Perhaps someone else can come up with something.
