clamp-min

Input Stack: minValue: Double expr: TimeSeriesExpr

⇨

Output Stack: TimeSeriesExpr

Limit the minimum value of a time series by clamping values below a specified threshold. Any values less than the minimum will be set to the minimum value, while values at or above the minimum remain unchanged. This is the counterpart to :clamp-max for setting floor values.

Parameters

• expr: The time series expression to apply the minimum limit to
• minValue: The minimum allowed value (values below this will be clamped)

Behavior

• Values ≥ minValue: Remain unchanged
• Values < minValue: Are set to exactly minValue
• Missing data: NaN values are preserved as NaN

Examples

Setting a minimum threshold to prevent negative spikes:
