LOOKUP X-VALUE FROM A GIVEN Y-VALUE¶
Looks up the x-value on one or more curves that corresponds to a given y-value supplied from a dataset column. Use this worker when you need to find the x-axis position (e.g. time, displacement) at a specific response threshold defined in a tabular dataset.
When to use¶
Classification: process.
Tagged: curve, curve_group, dataset, interpolation, lookup, x-value, y-value.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves To Be Looked Up | curvestobelookedup | vector | — | ✓ | One or more curves (vector type, multi-select) from which the x-value will be looked up; each curve is searched for the y-value(s) provided by the dataset column. |
| Dataset | dataset | dataset | — | ✓ | Tabular dataset whose rows supply the target y-values used for the lookup; must contain at least the column specified in the ‘col’ input. |
| Column With Y-Values | col | text | — | ✓ | Name of the dataset column that holds the y-values at which the corresponding x-values should be found; select from the columns present in the connected dataset. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_lookup_yvalueat_output_1 | curves_lookup_yvalueat_output_1 | dataset | Dataset containing the looked-up x-values for each input curve and each target y-value row from the dataset column. |
