You might be looking for a [scripted metric aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-scripted-metric-aggregation.html) here, which is not supported in Kibana at this time.

To operate on ratios (which is a common use case), I'd suggest a couple of approaches:

1. At the current time, see if you can index the ratio directly as a field, either at data ingest time using Logstash or after the fact using Watcher
2. Wait until Elasticsearch 2.0 and a subsequent Kibana release that adds support for a [bucket script aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/master/search-aggregations-pipeline-bucket-script-aggregation.html), which will be able to do arithmetic on results of aggregations.
