# xarray.DataArray.count

`DataArray.``count`(dim=None, axis=None, **kwargs)

  Reduce this DataArray’s data by applying count along some dimension(s).

  Parameters:

  - dim (str or sequence of str, optional) – Dimension(s) over which to apply count.
  - axis (int or sequence of int, optional) – Axis(es) over which to apply count. Only one of the ‘dim’ and ‘axis’ arguments can be supplied. If neither are supplied, then count 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 count on this object’s data.

  Returns: | reduced – New DataArray object with count applied to its data and the indicated dimension(s) removed.
  Return type: | DataArray
