Rate

Per second

Function	Description	Example
`per_second()`	Graph the rate at which the metric is changing per second.	`per_second(<METRIC_NAME>{*})`

Per minute

Function	Description	Example
`per_minute()`	Graph the rate at which the metric is changing per minute.	`per_minute(<METRIC_NAME>{*})`

Per hour

Function	Description	Example
`per_hour()`	Graph the rate at which the metric is changing per hour.	`per_hour(<METRIC_NAME>{*})`

Delta time

Function	Description	Example
`dt()`	Graph the time difference in seconds between submitted points.	`dt(<METRIC_NAME>{*})`

Delta value

Function	Description	Example
`diff()`	Graph the delta of the metric.	`diff(<METRIC_NAME>{*})`

Monotonic Delta value

Function	Description	Example
`monotonic_diff()`	Graph the delta of the metric like `diff()` but only if the delta is positive.	`monotonic_diff(<METRIC_NAME>{*})`

Derivative

Function	Description	Example
`derivative()`	Graph the derivative (diff/dt) of the metric.	`derivative(<METRIC_NAME>{*})`
