Can I make a column that is a sum divided by time range up right? For example, I have one column that is a top 10 by bytes transferred. I want to display the mbit/sec for the host beside it. I can pre-do some of the math in logstash via ruby if necessary (bytes to bits, etc) but I can't figure out how to take the value and divide it by whatever time is picked. I don't really want the average - there may be hundreds of thousands of packets, so the average size in bytes isn't what I want. I want to make a bytes/time column, where /time is based on the number of seconds in the time picker. ---

This is not supported in Kibana today, but we have an open issue for this kind of metric math: [https://github.com/elastic/kibana/issues/4646#issuecomment-130338994](https://github.com/elastic/kibana/issues/4646#issuecomment-130338994) ---
