public class BubbleVisualization
extends AbstractScatterplotVisualization
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,
                   boolean fill)

Constructor.

Parameters:

task - Visualization task

scaling - Scaling function

fill - Fill flag

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

resultChanged

public void resultChanged(Result current)

Description copied from interface: ResultListener

Notify that the current result has changed substantially.

Specified by:

resultChanged in interface ResultListener

Overrides:

resultChanged in class AbstractScatterplotVisualization

Parameters:

current - Result that has changed.

setupCSS

private void setupCSS(SVGPlot svgp,
            ClassStylingPolicy policy)

Registers the Bubble-CSS-Class at a SVGPlot.

Parameters:

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

policy - Clustering to use

getScaledForId

protected double getScaledForId(DBIDRef 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.
