xarray.DataArray.reindex¶
-
DataArray.
reindex
(indexers: Mapping[Hashable, Any] = None, method: str = None, tolerance=None, copy: bool = True, fill_value=<NA>, **indexers_kwargs) → xarray.core.dataarray.DataArray¶ Conform this object onto the indexes of another object, filling in missing values with
fill_value
. The default fill value is NaN.Parameters: - indexers (dict, optional) – Dictionary with keys given by dimension names and values given by arrays of coordinates tick labels. Any mis-matched coordinate values will be filled in with NaN, and any mis-matched dimension names will simply be ignored. One of indexers or indexers_kwargs must be provided.
- copy (bool, optional) – If
copy=True
, data in the return value is always copied. Ifcopy=False
and reindexing is unnecessary, or can be performed with only slice operations, then the output may share memory with the input. In either case, a new xarray object is always returned. - method ({None, 'nearest', 'pad'/'ffill', 'backfill'/'bfill'}, optional) –
Method to use for filling index values in
indexers
not found on this data array:- None (default): don’t fill gaps
- pad / ffill: propagate last valid index value forward
- backfill / bfill: propagate next valid index value backward
- nearest: use nearest valid index value
- tolerance (optional) – Maximum distance between original and new labels for inexact
matches. The values of the index at the matching locations must
satisfy the equation
abs(index[indexer] - target) <= tolerance
. - fill_value (scalar, optional) – Value to use for newly missing values
- **indexers_kwarg ({dim: indexer, ..}, optional) – The keyword arguments form of
indexers
. One of indexers or indexers_kwargs must be provided.
Returns: reindexed – Another dataset array, with this array’s data but replaced coordinates.
