xarray.DataArray.interpolate_na¶
-
DataArray.
interpolate_na
(dim=None, method: str = 'linear', limit: Optional[int] = None, use_coordinate: Union[bool, str] = True, **kwargs) → xarray.core.dataarray.DataArray¶ Interpolate values according to different methods.
- Parameters
- dimstr
Specifies the dimension along which to interpolate.
- method{‘linear’, ‘nearest’, ‘zero’, ‘slinear’, ‘quadratic’, ‘cubic’,
‘polynomial’, ‘barycentric’, ‘krog’, ‘pchip’, ‘spline’, ‘akima’}, 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’, and akima: use their respective``scipy.interpolate`` classes.
- use_coordinateboolean 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.
- limitint, default None
Maximum number of consecutive NaNs to fill. Must be greater than 0 or None for no limit.
- Returns
- DataArray
