REMOVE OFFSETS BASED ON THE FIRST POINT¶
Removes the offset from one or more curves by subtracting the first point’s X and Y values, making all curves relative to their own starting point. Use this to align curves that share a common baseline or to eliminate sensor/measurement offsets before further analysis.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves | curve | vector | — | One or more input curves (X/Y vector pairs) whose offsets will be removed; each curve is shifted so its first point becomes the origin (0, 0). Optional — leave empty to produce no output. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_relative_to_first_point_output_1 | curve_relative_to_first_point_output_1 | vector | Offset-corrected curve(s) where each input curve has been translated so that its first data point is at the origin; one output curve is produced per input curve. |
