Class EvaluationVisualization

java.lang.Object

de.lmu.ifi.dbs.elki.visualization.visualizers.AbstractVisFactory

de.lmu.ifi.dbs.elki.visualization.visualizers.visunproj.EvaluationVisualization

All Implemented Interfaces:

VisualizationProcessor, VisFactory

public class EvaluationVisualization
extends AbstractVisFactory

Pseudo-Visualizer, that lists the cluster evaluation results found. TODO: add indication/warning when values are out-of-bounds. TODO: Find a nicer solution than the current hack to only display the evaluation results for the currently active clustering.
