COMPUTE CURVE RELATIVE TO THE FIRST POINT¶
Offsets a curve so that its first data point becomes the new origin (zero reference). Use this worker when you need to normalize a curve relative to its starting value before further analysis or comparison.
When to use¶
Classification: process.
Tagged: curve, first_point, normalization, offset, relative, transform.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | Input curve (X/Y vector pair) to be offset; the Y-values will be shifted so that the first point becomes zero. Accepts any general-purpose curve — leave unconnected only if the worker is used in a pass-through chain. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_relative_to_first_point_output_1 | curve_relative_to_first_point_output_1 | vector | Transformed curve whose Y-values are offset by the negative of the first Y-value, making the first point the zero reference; X-values are unchanged. |
