FIT THE CURVE USING ANY REGION NEAR THE INITIAL POINT TO SMOOTH THE INITIAL PORTION¶
Fits a polynomial to the initial region of a curve to produce a smoothed version of its starting portion. Use this worker when raw curve data has noisy or artefact-laden early values that need to be replaced with a clean best-fit approximation.
When to use¶
Classification: process.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | curve | vector | — | Input curve (or batch of curves) whose initial portion is to be smoothed; accepts a vector time-history or X-Y curve in d3VIEW curve format. | |
| Order | order | scalar | 3 | Polynomial order used for the best-fit regression over the initial region; default is 3 (cubic); increase for more flexible fits, decrease to enforce smoother, stiffer starts. | |
| Start Value | start_value | scalar | 0 | Override for the x-axis start value of the fit region; leave at default (0) to use the curve’s own first data point as the region origin. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Best fit Curve | curve_o_1 | vector | Output curve with the initial portion replaced by the polynomial best-fit result, preserving the original data beyond the fitted region. |
