DATASET SCALE COLUMN¶
Multiplies every value in a chosen dataset column by a numeric scale factor, returning the modified dataset. Use this worker whenever a single column needs unit conversion, normalization, or any constant-factor rescaling within a workflow.
When to use¶
Classification: process.
Tagged: column_scaling, dataset_transform, multiplier, normalization, scale_column, unit_conversion.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Choose Dataset | dataset_1 | dataset | — | Input dataset containing the column to be scaled; accepts any tabular dataset available in the workflow — leave unconnected only if the worker is being configured offline. | |
| Choose Column | col_to_scale | scalar | — | Name of the column whose numeric values will be multiplied by the scale factor; the pick-list is populated dynamically from dataset_1. | |
| Scale Factor | scale_factor | text | 1 | Dimensionless numeric multiplier applied to every value in the selected column (default 1, i.e. no change); provide a float or integer, e.g. 0.001 to convert mm → m. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Dataset with Scaled Column | dataset_scale_colmn_output_1 | dataset | Copy of the input dataset with the selected column values replaced by their scaled equivalents; all other columns are unchanged. |
