Type Parameters:
V - the vertex type
E - the edge type
All Implemented Interfaces:
LayoutAlgorithm2D<V,E>

public class RescaleLayoutAlgorithm2D<V,E> extends BaseLayoutAlgorithm2D<V,E>
A layout algorithm which re-scales vertex positions to (center-scale,center+scale) in all dimensions. The algorithm first subtracts the mean on each axis separately, then all values are adjusted so that the maximum magnitude becomes scale. The result is finally translated back to the old center. This procedure preserves the aspect ratio.
