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 number of intervals in the histogram is 10% of the number of instances in the dataset, otherwise number of intervals is equal to the width of this panel in pixels minus 6 (if that 10% figure is > width).
