Public Member Functions
AxisRange &	auto_scale (bool enabled=true)
	Enable or disable auto-scaling.
float	normalise (float v) const noexcept
	Map a value into [0, 1] within this range.
AxisRange &	range (float lo, float hi)
	Set the explicit [min, max] domain.
AxisRange &	scale_if (std::function< bool()> predicate)
	Gate auto-scaling behind an arbitrary bool-returning callable.
float	to_ndc (float v) const noexcept
	Map a value into [-1, 1] NDC within this range.

Public Attributes
bool	auto_scaling { false }
float	max { 1.F }
float	min { -1.F }
std::function< bool()>	scale_predicate
	When set, evaluated before applying a data-derived range.

Detailed Description

Scalar domain extent for one plot axis.

Maps raw double values in [min, max] to the normalised render space expected by the geometry function. When auto_scaling is true, min and max are recomputed from the series data on every process() call, subject to any predicate set via scale_if().

Fluent setters return AxisRange& for chained construction:

AxisRange{}.range(-1.F, 1.F)
AxisRange{}.auto_scale()
AxisRange{}.range(0.F, 440.F).auto_scale(false)
AxisRange{}.scale_if([&active]{ return active.load(); })
