argmax(self, dim=None, axis=None, skipna=None, **kwargs)¶
Reduce this DataArray’s data by applying argmax along some dimension(s).
dim (str or sequence of str, optional) – Dimension(s) over which to apply argmax.
axis (int or sequence of int, optional) – Axis(es) over which to apply argmax. Only one of the ‘dim’ and ‘axis’ arguments can be supplied. If neither are supplied, then argmax is calculated over axes.
skipna (bool, optional) – If True, skip missing values (as marked by NaN). By default, only skips missing values for float dtypes; other dtypes either do not have a sentinel missing value (int) or skipna=True has not been implemented (object, datetime64 or timedelta64).
keep_attrs (bool, optional) – If True, the attributes (attrs) will be copied from the original object to the new one. If False (default), the new object will be returned without attributes.
**kwargs (dict) – Additional keyword arguments passed on to the appropriate array function for calculating argmax on this object’s data.
reduced – New DataArray object with argmax applied to its data and the indicated dimension(s) removed.
