DataArray.
reindex
(indexers=None, method=None, tolerance=None, copy=True, fill_value=<NA>, **indexers_kwargs)¶ 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) – Ifcopy=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 inindexers
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 or dict-like, optional) – Value to use for newly missing values. If a dict-like, maps variable names (including coordinates) to fill values. Use this data array’s name to refer to the data array’s values.
**indexers_kwargs (
{dim: indexer, ...}
, optional) – The keyword arguments form ofindexers
. One of indexers or indexers_kwargs must be provided.
- Returns
reindexed (
DataArray
) – Another dataset array, with this array’s data but replaced coordinates.
