DataArray.bfill(dim, limit=None)[source]

Fill NaN values by propogating values backward

Requires bottleneck.

  • dim (str) – Specifies the dimension along which to propagate values when filling.

  • limit (int, default: None) – The maximum number of consecutive NaN values to backward fill. In other words, if there is a gap with more than this number of consecutive NaNs, it will only be partially filled. Must be greater than 0 or None for no limit. Must be None or greater than or equal to axis length if filling along chunked axes (dimensions).
