SYNC POINTS SUCH THAT ALL CURVES HAVE THE SAME X-VALUES¶
Synchronises a collection of curves so that every curve shares the same set of x-axis values, interpolating (and optionally extrapolating) y-values to the merged x-grid. Use this worker before any operation that requires point-for-point curve alignment, such as averaging, differencing, or batch comparisons.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves In | curves_in | vector | — | Collection of one or more input curves (x/y vector pairs) to be synchronised onto a common x-grid; accepts multiple curves simultaneously. | |
| Extrapolate | extrapolate | scalar | no | Controls how y-values are computed when a curve’s x-range is shorter than the merged grid: ‘no’ (default) — no extrapolation, values are dropped; ‘yes’ — standard extrapolation; ‘yes_min_zero’ — extrapolate but clamp minimum to zero; ‘yes_first_last_value’ — pad with the first/last known value; ‘constant’ — hold the boundary constant; ‘zero’ — pad with zeros. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_sync_x_output_1 | curves_sync_x_output_1 | vector | The input curves remapped onto the unified x-grid, returned as a vector collection with identical x-values across all curves and interpolated/extrapolated y-values. |
