CONVERT VALUES OF X OR Y TO LOG SCALE¶
Applies a base-10 logarithm transformation to the X, Y, or both axes of a curve. Use this worker when you need to convert linear-scale curve data to log scale for visualisation, frequency analysis, or downstream log-space processing.
When to use¶
Classification: process.
Tagged: axis_transform, curve_transform, log10, log_scale, x_axis, y_axis.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Base Curve | base_curve | vector | — | Input curve (X/Y vector pair) whose axis values will be log-transformed; must contain strictly positive values on the axis being transformed. | |
| Axis | axis | string | x | Axis to apply the log transformation to: ‘x’ (X-axis only, default), ‘y’ (Y-axis only), or ‘xy’ (both axes simultaneously). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_to_Log_output_1 | curve_to_log_output_1 | vector | Output curve with the selected axis values replaced by their base-10 logarithm, preserving the original axis that was not transformed. |
