              de.lmu.ifi.dbs.elki.visualization.visualizers.vis2d.TooltipVisualizer<NV>

Type Parameters:

NV - Data type visualized.

All Implemented Interfaces:

Parameterizable, ProjectedVisualizer, Visualizer

public class TooltipVisualizer<NV extends NumberVector<NV,?>>
extends Projection2DVisualizer<NV>

Generates a SVG-Element containing Tooltips. Tooltips remain invisible until their corresponding Marker is touched by the cursor and stay visible as long as the cursor lingers on the marker.
