xarray.DataArray.roll¶
-
DataArray.
roll
(**shifts)¶ Roll this array by an offset along one or more dimensions.
Unlike shift, roll rotates all variables, including coordinates. The direction of rotation is consistent with
numpy.roll()
.Parameters: **shifts : keyword arguments of the form {dim: offset}
Integer offset to rotate each of the given dimensions. Positive offsets roll to the right; negative offsets roll to the left.
Returns: rolled : DataArray
DataArray with the same attributes but rolled data and coordinates.
