# Sample

Sample is used to resample an existing series at a constant frequency. This can be used in two primary scenarios:

* Data is coming in at a constant rate (such as daily), but some days no data was recorded. Rather than having gaps in the data, you can use Sample to resample at a daily rate to produce a complete series.
* Data is coming in at a constant rate (such as daily), but you would like a series that has data at a different rate (such as hourly or weekly).

Sample calculates its new points by using [interpolation](../cards-interpolation-usage/index.md#sample) between the existing data.
