.. _auto_dataset_digitize_column:

*DATASET DIGITIZE COLUMN*
=========================

Resamples a single dataset column to a fixed number of evenly-spaced points using digitization (linear interpolation). Use this worker to normalise column length before curve comparison, machine-learning ingestion, or any operation that requires uniform point counts.

When to use
-----------

Classification: **process**.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset containing the column to be digitized; must be a tabular dataset with at least the target column present.
   * - Column Name
     - column_name
     - scalar
     - —
     - 
     - Name of the column in dataset_1 to digitize; must match an existing column header exactly — populated dynamically from the connected dataset.
   * - Digitize Points
     - num_points
     - scalar
     - 100
     - 
     - Number of evenly-spaced output points to resample the column to (integer, default 100); increase for higher resolution, decrease for coarser representations.

Outputs

     - dataset
     - Output dataset identical in structure to the input but with the selected column resampled to the specified number of uniformly-spaced points.
