xarray.DataArray.shift

DataArray.shift(shifts=None, fill_value=<NA>, **shifts_kwargs)

Shift this array by an offset along one or more dimensions.

Only the data is moved; coordinates stay in place. Values shifted from beyond array bounds are replaced by NaN. This is consistent with the behavior of shift in pandas.

Parameters
shiftsMapping with the form of {dim: offset}

Integer offset to shift along each of the given dimensions. Positive offsets shift to the right; negative offsets shift to the left.

fill_value: scalar, optional

Value to use for newly missing values

**shifts_kwargs:

The keyword arguments form of shifts. One of shifts or shifts_kwarg must be provided.

Returns
shiftedDataArray

DataArray with the same coordinates and attributes but shifted data.
