public class RadVizPlotter
extends PlotterAdapter

A Radial coordinate Visualization, hence the name RadViz. The spring paradigm for displaying high-dimensional data has been quite successful. M lines radially eminate from the center of the circle and terminate at the perimeter in special special endpoints called dimensional anchors (DA). One end of a spring is attached to each DA. The other end of each spring is attached to a data point. The spring constant K_j has the value of the j-th coordinate of the data point. The data point values are typically locally normalized. Each data point is then displayed at the position that produces a spring force sum of 0. If all m coordinates have the same value the data point lies exactly in the center of the circle independently of the actual values. If the point is a unit vector point it lies exaclty at the fixed point on the edge of the circle, where the spring for that dimension is fixed. Many points can map to the same position. This mapping represents a non-linear transformation of the data that preserves certain symmetries.

Creates a new RadViz plotter from the given data table.

Method Detail

getPlotterCondition

public PlotterCondition getPlotterCondition()

Description copied from class: PlotterAdapter

Returns a BasicPlotterCondition allowing for all DataTables. Subclasses should override this method in order to indicate that they might not be able to handle certain data tables.

Specified by:

getPlotterCondition in interface Plotter

Overrides:

getPlotterCondition in class PlotterAdapter

setDataTable

public void setDataTable(DataTable dataTable)

Description copied from class: PlotterAdapter

Since this method already adds this object as a listener, all methods overriding this one should invoke the super method.

Specified by:

setDataTable in interface Plotter

Overrides:

setDataTable in class PlotterAdapter

setPlotColumn

public void setPlotColumn(int index,
                          boolean plot)

Description copied from class: PlotterAdapter

Does nothing. Subclasses should override this method if they want to allow plot column selection. In this case, the method PlotterAdapter.getPlotColumn(int) should also be overriden.

Specified by:

setPlotColumn in interface Plotter

Overrides:

setPlotColumn in class PlotterAdapter

getPlotColumn

public boolean getPlotColumn(int index)

Description copied from class: PlotterAdapter

Returns false. Subclasses should override this method and return true for the columns which should be plotted.

Specified by:

getPlotColumn in interface Plotter

Overrides:

getPlotColumn in class PlotterAdapter

getPlotName

public java.lang.String getPlotName()

Description copied from class: PlotterAdapter

Returns null. Subclasses might return another name more fitting the plot selection box or list.

Specified by:

getPlotName in interface Plotter

Overrides:

getPlotName in class PlotterAdapter

Specified by:

getOptionsComponent in interface Plotter

Overrides:

getOptionsComponent in class PlotterAdapter

canHandleZooming

Specified by:

canHandleZooming in interface Plotter

Overrides:

canHandleZooming in class PlotterAdapter

setZooming

public void setZooming(int zooming)

Description copied from class: PlotterAdapter
