.. _auto_dataset_get_curves_from_column:

*GET CURVES FROM A COLUMN*
==========================

Extracts all curves stored within a specified dataset column and returns them as a vector of curve objects. Use this worker when a dataset column contains embedded curve data that needs to be unpacked for downstream curve-based processing or visualization.

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

Classification: **process**.

Tagged: ``column``, ``curves``, ``dataset``, ``extract``, ``transformations``, ``vector``.

     - 
     - Input dataset containing at least one column that holds embedded curve objects; leave unconnected only if curves will be supplied via a chained transformation context.
   * - Choose Curve Column

     - Name of the dataset column whose cells contain curve data to extract; select from the dynamically populated list derived from dataset_1 (single selection, quoted string).
