.. _auto_dataset_rename_curves_in_column:

*DATASET RENAME CURVES IN COLUMN*
=================================

Renames the curve objects stored inside a specified curve-column of a dataset, using values drawn from a second column as the new names. Use this worker when downstream steps require consistent or human-readable curve identifiers before plotting, correlation, or export.

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

Classification: **process**.

Tagged: ``column``, ``curve_column``, ``curves``, ``dataset``, ``rename``, ``transform``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Choose Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset containing at least one curve-typed column whose curve names are to be updated; leave unconnected only if the worker is being tested in isolation.
   * - Choose Curve Column
     - curve_col
     - text
     - —
     - 
     - Name of the dataset column that holds the curve objects to be renamed; must be a curve-typed column present in dataset_1.
   * - Name By
     - name_by
     - text
     - —
     - 
     - Name of the dataset column whose row values will become the new names for the corresponding curves in curve_col; typically a string/label column from the same dataset.

Outputs
-------

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

   * - Label
     - ID
     - Type
     - Description
   * - dataset_rename_columns_output_1
     - dataset_rename_columns_output_1
     - dataset
     - A copy of the input dataset in which every curve in the selected curve-column has been renamed according to the values from the name_by column; all other columns are unchanged.
