I'm using Kibana 6.8.2, and I have an index with next parameters
* message_total_size * message_total_count * date * country
I want to make a Vertical Bar visualization to show the average message size per day (using date histogram), but I cannot find a way to make the division like:
I tried with the Average aggregation, but it doesn't work form in this case (at least I cannot see how), because is making the average based on the number of documents in the index.
I'd appreciate any help, thanks
