series_by_role()

MAYAFLUX_API std::vector< std::span< const double > > MayaFlux::Portal::Forma::Plot::series_by_role	(	const Kakshya::PlotContainer &	container,
		Kakshya::DataDimension::Role	role
	)

Collect all series from processed_data whose DataDimension role matches role.

Returns spans pointing directly into the DataVariant storage — no copy. Returns an empty vector if no series carry the role or if any matching variant does not hold vector<double>.

Parameters

container	PlotContainer after process_default() has been called.
role	DataDimension::Role to match.
