xarray.core.rolling.DataArrayRolling.construct¶
-
DataArrayRolling.
construct
(window_dim, stride=1, fill_value=<NA>)¶ Convert this rolling object to xr.DataArray, where the window dimension is stacked as a new dimension
Parameters: window_dim: str
New name of the window dimension.
stride: integer, optional
Size of stride for the rolling window.
fill_value: optional. Default dtypes.NA
Filling value to match the dimension size.
Returns: DataArray that is a view of the original array. The returned array is
not writeable.
Examples
>>> da = DataArray(np.arange(8).reshape(2, 4), dims=('a', 'b')) >>> >>> rolling = da.rolling(a=3) >>> rolling.to_datarray('window_dim') <xarray.DataArray (a: 2, b: 4, window_dim: 3)> array([[[np.nan, np.nan, 0], [np.nan, 0, 1], [0, 1, 2], [1, 2, 3]], [[np.nan, np.nan, 4], [np.nan, 4, 5], [4, 5, 6], [5, 6, 7]]]) Dimensions without coordinates: a, b, window_dim >>> >>> rolling = da.rolling(a=3, center=True) >>> rolling.to_datarray('window_dim') <xarray.DataArray (a: 2, b: 4, window_dim: 3)> array([[[np.nan, 0, 1], [0, 1, 2], [1, 2, 3], [2, 3, np.nan]], [[np.nan, 4, 5], [4, 5, 6], [5, 6, 7], [6, 7, np.nan]]]) Dimensions without coordinates: a, b, window_dim
