public class BubbleVisualization<NV extends NumberVector<NV,?>>
extends P2DVisualization<NV>
implements DataStoreListener

Generates a SVG-Element containing bubbles. A Bubble is a circle visualizing an outlierness-score, with its center at the position of the visualized object and its radius depending on the objects score.

Constructor Detail

BubbleVisualization

public BubbleVisualization(VisualizationTask task,
                           ScalingFunction scaling)

Constructor.

Parameters:

task - Visualization task

scaling - Scaling function

Method Detail

destroy

public void destroy()

Description copied from interface: Visualization

Destroy the visualization. Called after the elements have been removed from the document. Implementations should remove their listeners etc.

Specified by:

destroy in interface Visualization

Overrides:

destroy in class AbstractVisualization

redraw

public void redraw()

Description copied from class: AbstractVisualization

Perform a full redraw.

Specified by:

redraw in class AbstractVisualization

contentChanged

public void contentChanged(DataStoreEvent e)

Description copied from interface: DataStoreListener

Invoked after objects of the datastore have been updated, inserted or removed in some way.

Specified by:

contentChanged in interface DataStoreListener

Parameters:

e - the update event

setupCSS

private void setupCSS(SVGPlot svgp,
                      Clustering<? extends Model> clustering)

Registers the Bubble-CSS-Class at a SVGPlot.

Parameters:

svgp - the SVGPlot to register the Tooltip-CSS-Class.

clustering - Clustering to use

getScaledForId

protected Double getScaledForId(DBID id)

Convenience method to apply scalings in the right order.

Parameters:

id - object ID to get scaled score for

Returns:

a Double representing a outlierness-score, after it has modified by the given scales.
