void	calculatePositionsGraph (const Points &points, const Transformation &transformation, QVector< QPointF > &positionsGraph) const
	Convert screen positions to graph positions.

double	functionArea (const QVector< QPointF > &positionsGraph) const
	Use trapezoidal approximation to compute area under the function. Does not apply to relation.

void	insertSubintervalsAndLoadDistances (int subintervalsPerInterval, const QVector< QPointF > &positionsGraph, QVector< QPointF > &positionsGraphWithSubintervals, QVector< QString > &distanceGraphForward, QVector< QString > &distancePercentForward, QVector< QString > &distanceGraphBackward, QVector< QString > &distancePercentBackward) const
	Insert the specified number of subintervals into each interval.

virtual void	loadPotentialExportVector (QVector< QString > &x, QVector< QString > &y, const Transformation &transformation, QVector< bool > &isPotentialExportAmbiguity) const
	Load isPotentialExportAmbiguity vector. Default in base class is to load false values since there are no ambiguities.

void	loadXY (const QVector< QPointF > &positionsGraph, const DocumentModelCoords &modelCoords, const DocumentModelGeneral &modelGeneral, const MainWindowModel &modelMainWindow, const Transformation &transformation, QVector< QString > &x, QVector< QString > &y) const
	Load x and y coordinate vectors.

double	polygonAreaForSimplyConnected (const QVector< QPointF > &points) const
	Area in polygon using Shoelace formula, which only works if polygon is simply connected.
