Convert a DataCollection of point-in-time values to its time-aggregated equivalent.

For example, if the collection has a Power data type in W, this method will return a collection with an Energy data type in kWh.

### Inputs

* **data \[Required]**

A houry, sub-hourly or daily data collection that can be aggregated over time to yield data of a different metric. (eg. a data collection of Power values in W).

### Outputs

* **data\_aggr**

The data collection aggregated over time. (eg. a data collection of Energy values in kWh).
