pandas.Panel.reindex

Panel.reindex(items=None, major_axis=None, minor_axis=None, **kwargs)

Conform Panel to new index with optional filling logic, placing NA/NaN in locations having no value in the previous index. A new object is produced unless the new index is equivalent to the current one and copy=False

Parameters:

items, major_axis, minor_axis : array-like, optional (can be specified in order, or as keywords)

New labels / index to conform to. Preferably an Index object to avoid duplicating data

method : {‘backfill’, ‘bfill’, ‘pad’, ‘ffill’, None}, default None

Method to use for filling holes in reindexed DataFrame pad / ffill: propagate last valid observation forward to next valid backfill / bfill: use NEXT valid observation to fill gap

copy : boolean, default True

Return a new object, even if the passed indexes are the same

level : int or name

Broadcast across a level, matching Index values on the passed MultiIndex level

fill_value : scalar, default np.NaN

Value to use for missing values. Defaults to NaN, but can be any “compatible” value

limit : int, default None

Maximum size gap to forward or backward fill

takeable : boolean, default False

treat the passed as positional values

Returns:

reindexed : Panel

>>> df.reindex(index=[date1, date2, date3], columns=['A', 'B', 'C'])
