Examples of weka.gui.AttributeVisualizationPanel

weka.gui.AttributeVisualizationPanel
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); @author Ashraf M. Kibriya (amk14@cs.waikato.ac.nz) @version $Revision: 6889 $
