interpolate_na
(dim=None, method='linear', limit=None, use_coordinate=True, **kwargs)¶ Interpolate values according to different methods.
Parameters: - dim : str
Specifies the dimension along which to interpolate.
- method : {‘linear’, ‘nearest’, ‘zero’, ‘slinear’, ‘quadratic’, ‘cubic’,
‘polynomial’, ‘barycentric’, ‘krog’, ‘pchip’, ‘spline’}, optional
String indicating which method to use for interpolation:
- ‘linear’: linear interpolation (Default). Additional keyword
arguments are passed to
numpy.interp
- ‘nearest’, ‘zero’, ‘slinear’, ‘quadratic’, ‘cubic’,
‘polynomial’: are passed to
scipy.interpolate.interp1d
. If method==’polynomial’, theorder
keyword argument must also be provided. - ‘barycentric’, ‘krog’, ‘pchip’, ‘spline’: use their respective
scipy.interpolate
classes.
- ‘linear’: linear interpolation (Default). Additional keyword
arguments are passed to
- use_coordinate : boolean or str, default True
Specifies which index to use as the x values in the interpolation formulated as y = f(x). If False, values are treated as if eqaully-spaced along dim. If True, the IndexVariable dim is used. If use_coordinate is a string, it specifies the name of a coordinate variariable to use as the index.
- limit : int, default None
Maximum number of consecutive NaNs to fill. Must be greater than 0 or None for no limit.
Returns: - Dataset
