Panel.reindex_axis()

labels : array-like

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

axis : {0, 1, 2, ?items?, ?major_axis?, ?minor_axis?}

method : {None, ?backfill?/?bfill?, ?pad?/?ffill?, ?nearest?}, optional

Method to use for filling holes in reindexed DataFrame:

• default: don?t fill gaps
• pad / ffill: propagate last valid observation forward to next valid
• backfill / bfill: use next valid observation to fill gap
• nearest: use nearest valid observations 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

limit : int, default None

Maximum number of consecutive elements to forward or backward fill

tolerance : optional

Maximum distance between original and new labels for inexact matches. The values of the index at the matching locations most satisfy the equation abs(index[indexer] - target) <= tolerance.
