Class MixedTreeMapAlgorithm

java.lang.Object

org.conqat.lib.commons.treemap.MixedTreeMapAlgorithm

All Implemented Interfaces:

ITreeMapLayoutAlgorithm

public class MixedTreeMapAlgorithm
extends java.lang.Object
implements ITreeMapLayoutAlgorithm

A hybrid layout algorithm that applies both the StripeTreeMapAlgorithm and (near the leaves) the SquarifiedTreeMapAlgorithm to obtain good sorting/locality while getting rectangles that are "more square". The approach is described in Vliegen, von Wijk, van der Linden: "Visualizing Business Data with Generalized Treemaps".

Method Detail

layout

public <T> void layout(ITreeMapNode<T> rootNode,
                       java.awt.geom.Rectangle2D targetArea)

Modifies the given tree by adding layout information. The topmost rectangle will be the given target rectangle. All other nodes will be assigned rectangles which sum exactly to the the rectangle of they target node and have areas proportional to their size.
