xarray.DataArray.cumsum¶
-
DataArray.
cumsum
(dim=None, axis=None, skipna=None, keep_attrs=False, **kwargs)¶ Apply cumsum along some dimension of DataArray.
Parameters: - dim : str or sequence of str, optional
Dimension over which to apply cumsum.
- axis : int or sequence of int, optional
Axis over which to apply cumsum. Only one of the ‘dim’ and ‘axis’ arguments can be supplied.
- 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 cumsum.
Returns: - cumvalue : DataArray
New DataArray object with cumsum applied to its data along the indicated dimension.
