Interpolate timeseries to a single timebasis.




Documentation
:::::::::::::

The new timebasis can either be an existing timebasis in the ADAF-file or a
timebasis with a timestep defined by the user. The timeseries that will be
interpolated are selected in a list. The output file will contain a single
system and raster with all the chosen timeseries. Signals in the
configuration GUI corresponds to timeseries in the ADAF.

Interpolation methods are chosen separately for different groups of data
types: non-numeric, integer, other numeric.

Methods:

:zero: Zero-order hold (preceding sample)
:nearest: Nearest neighbor interpolation (nearest sample)
:linear: Linear interpolation
:quadratic: Quadratic spline interpolation
:cubic: Cubic spline interpolation

Notable behaviors:

- Extrapolated values are masked.
- Non-finite values are treated as NaN.
- Fallback to `nearest` when usable samples too few for the selected
  method (fallback might change in future versions).

Output ports

    **port1**  adaf
        Interpolated ADAF




Configuration
.............

    **(no label)** (bool_interp_method)
        Method used to interpolate boolean, text, and byte string data
    **Time step** (dt)
        Time step in new timebasis. If old timebasis is of type datetime this is considered to be in seconds.
    **(no label)** (int_interp_method)
        Method used to interpolate integer data
    **(no label)** (interpolation_method)
        Method used to interpolate other data types
    **Timebasis to use for interpolation** (new_tb)
        Timebasis to use as new timebasis for selected timeseries
    **Export time basis only** (only_timebasis)
        Choose to only export the time basis
    **Resample all signals** (resample_all_rasters)
        Apply resampling to all signals
    **Choose signals** (ts)
        Choose signals to interpolate
    **Time step approach** (use_dt)
        Choose between a custom time step and using an existing.
