I want to divide two metrics which were calculated by sum and count at the y-axis in Bar-graphs.

I went through some discussion, for the newer version there's supposed to `calculation` field in metrics aggregation. But it's not there in my case. Actually, it's already deployed on the server so I can't update it. I know it's possible in `Timelion` but I want a different field in the x-axis, which is not related to any time series.

The Kibana [aggregation reference](https://www.elastic.co/guide/en/kibana/current/aggregation-reference.html#other-features) lists "math on aggregated data" as a feature that only exists in TSVB, Timelion, and Vega. Since you said that you want a different field on the X axis, you probably need to use Vega.
