public class AttributeVisualizationPanel

extends javax.swing.JPanel

Creates a panel that shows a visualization of an attribute in a dataset. For nominal attribute it shows a bar plot, with each bar corresponding to each nominal value of the attribute with its height equal to the frequecy that value appears in the dataset. For numeric attributes, it displays a histogram. The width of an interval in the histogram is calculated using Scott's(1979) method:
intervalWidth = Max(1, 3.49*Std.Dev*numInstances^(1/3)) Then the number of intervals is calculated by:
intervals = max(1, Math.round(Range/intervalWidth);

Constructor Detail

AttributeVisualizationPanel

public AttributeVisualizationPanel()

Constructor - If used then the class will not show the class selection combo box.

AttributeVisualizationPanel

public AttributeVisualizationPanel(boolean showColouringOption)

Constructor.

Parameters:

showColouringOption - - should be true if the class selection combo box is to be displayed with the histogram/barplot, or false otherwise. P.S: the combo box is always created it just won't be shown if showColouringOption is false.

Method Detail

public void setInstances(Instances newins)

Sets the instances for use

Parameters:

newins - a set of Instances

getColorBox

public javax.swing.JComboBox getColorBox()

Returns the class selection combo box if the parent component wants to place it in itself or in some component other than this component.

getColoringIndex

public int getColoringIndex()

Get the coloring (class) index for the plot

Returns:

an int value

setColoringIndex

public void setColoringIndex(int ci)

Set the coloring (class) index for the plot

Parameters:

ci - an int value

setAttribute

public void setAttribute(int index)

Tells the panel which attribute to visualize.

Parameters:

index - The index of the attribute

calcGraph

public void calcGraph()

Recalculates the barplot or histogram to display, required usually when the attribute is changed or the component is resized.

public java.lang.String getToolTipText(java.awt.event.MouseEvent ev)

Returns "<nominal value> [<nominal value count>]" if displaying a bar plot and mouse is on some bar. If displaying histogram then it
