Class VisualizerParameterizer

java.lang.Object

de.lmu.ifi.dbs.elki.visualization.VisualizerParameterizer

public class VisualizerParameterizer
extends java.lang.Object

Utility class to determine the visualizers for a result class. You really should use the parameterization API to configure this class. Manually populating the factory collection is cumbersome, and the parameterization API takes care of this.
