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);
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);

构造器详细资料
-
AttributeVisualizationPanel
public AttributeVisualizationPanel()Constructor - If used then the class will not show the class selection combo box. -
AttributeVisualizationPanel
public AttributeVisualizationPanel(boolean showColouringOption) Constructor.- 参数:
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.

int
value
-
setColoringIndex
public void setColoringIndex(int ci) Set the coloring (class) index for the plot- 参数:
