.. _auto_dataset_get_curve_from_column:

*CURVE FROM COLUMN*
===================

Collects all row values from a specified numeric column in a dataset and assembles them into a single curve (vector). Use this worker when you need to extract a 1-D signal or response history stored as a dataset column for downstream curve operations.

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

Classification: **process**.

Tagged: ``column_to_vector``, ``curve``, ``curve_extraction``, ``dataset``, ``transform``.

Inputs

     - Description
   * - Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset whose rows contain the values to be extracted; each row contributes one point to the output curve. Optional — leave unconnected only if the worker is being configured in isolation.
   * - Column Name
     - col_name
     - float
     - —
     - 
     - Name of the numeric column in dataset_1 whose row values will form the output curve; must resolve to a number-typed column — selection is driven dynamically by the connected dataset.

     - vector
     - 1-D vector (curve) composed of all row values from the selected column, in row order; suitable for direct use in curve-transform or plotting workers.
