public class ClustererAssignmentsPlotInstances
extends AbstractPlotInstances

A class for generating plottable cluster assignments.

Example usage:

 Instances train = ... // from somewhere
 Instances test = ... // from somewhere
 Clusterer cls = ... // from somewhere
 // build and evaluate clusterer
 cls.buildClusterer(train);
 ClusterEvaluation eval = new ClusterEvaluation();
 eval.setClusterer(cls);
 eval.evaluateClusterer(test);
 // generate plot instances
 ClustererPlotInstances plotInstances = new ClustererPlotInstances();
 plotInstances.setClusterer(cls);
 plotInstances.setInstances(test);
 plotInstances.setClusterer(cls);
 plotInstances.setClusterEvaluation(eval);
 plotInstances.setUp();
 // generate visualization
 VisualizePanel visPanel = new VisualizePanel();
 visPanel.addPlot(plotInstances.getPlotData("plot name"));
 // clean up
 plotInstances.cleanUp();
