apply_auto_scale()

MAYAFLUX_API void MayaFlux::Portal::Forma::Plot::apply_auto_scale	(	AxisRange &	range,
		const std::vector< std::span< const double > > &	series
	)

Apply auto-scaling to an AxisRange from a set of series.

Computes the union [min, max] over all provided series and updates range in place. No-op if series is empty or range.auto_scale is false.
