# xarray.computation.rolling.DatasetRolling

### *class* xarray.computation.rolling.DatasetRolling(obj, windows, min_periods=None, center=False)[[source]](https://github.com/pydata/xarray/blob/main/xarray/computation/rolling.py#L875-L1123)

#### \_\_init_\_(obj, windows, min_periods=None, center=False)[[source]](https://github.com/pydata/xarray/blob/main/xarray/computation/rolling.py#L878-L930)

Moving window object for Dataset.
You should use Dataset.rolling() method to construct this object
instead of the class constructor.

* **Parameters:**
  * **obj** ([`Dataset`](xarray.Dataset.html.md#xarray.Dataset)) – Object to window.
  * **windows** ([mapping](https://docs.python.org/3/glossary.html#term-mapping) of [hashable](../user-guide/terminology.html.md#term-name) to [`int`](https://docs.python.org/3/builtins/functions.html#int)) – A mapping from the name of the dimension to create the rolling
    window along (e.g. time) to the size of the moving window.
  * **min_periods** ([`int`](https://docs.python.org/3/builtins/functions.html#int), *default*: [`None`](https://docs.python.org/3/builtins/constants.html#None)) – Minimum number of observations in window required to have a value
    (otherwise result is NA). The default, None, is equivalent to
    setting min_periods equal to the size of the window.
  * **center** ([`bool`](https://docs.python.org/3/builtins/functions.html#bool) or [mapping](https://docs.python.org/3/glossary.html#term-mapping) of [hashable](../user-guide/terminology.html.md#term-name) to [`bool`](https://docs.python.org/3/builtins/functions.html#bool), *default*: [`False`](https://docs.python.org/3/builtins/constants.html#False)) – Set the labels at the center of the window. The default, False,
    sets the labels at the right edge of the window.
* **Returns:**
  **rolling** ([`type`](https://docs.python.org/3/builtins/functions.html#type) of `input argument`)
