In Kibana 3, I can convert the y-axis of a histogram into events per second using the settings (by clicking the checkbox at: Settings -\> Panel -\> Transform Series -\> [] Seconds). As I understand it, that feature divides the Y value by the width of the X-axis bucket in seconds.

How can I accomplish the same goal in Kibana 4?

You can't do that in core Kibana at the moment, but you can add a [Timelion](https://github.com/elastic/timelion/) plugin, which allows derivatives, and embed one of its charts in a dashboard.
