xarray.computation.rolling.DatasetCoarsen (original) (raw)

class xarray.computation.rolling.DatasetCoarsen(obj, windows, boundary, side, coord_func)[source]#

__init__(obj, windows, boundary, side, coord_func)[source]#

Moving window object.

Parameters:

• obj (Dataset or DataArray) – Object to window.
• windows (mapping of hashable to int) – A mapping from the name of the dimension to create the rolling exponential window along (e.g. time) to the size of the moving window.
• boundary ({"exact", "trim", "pad"}) – If ‘exact’, a ValueError will be raised if dimension size is not a multiple of window size. If ‘trim’, the excess indexes are trimmed. If ‘pad’, NA will be padded.
• side ('left' or 'right' or mapping from dimension to 'left' or 'right')
• coord_func (function (name) or mapping from coordinate name to function (name).)

Returns:
