generateXYChart

public org.jfree.chart.JFreeChart generateXYChart(java.util.List<Cluster> clusters,
                                                  java.lang.Integer firstAttributeIndex,
                                                  java.lang.String firstAttributeName,
                                                  java.lang.Integer secondAttributeIndex,
                                                  java.lang.String secondAttributeName)

Generates a XY chart visualizing the clusters found by a clustering algorithm. Limited to two dimensions (because the chart is 2D).

Parameters:

clusters - clusters found by a clustering algorithm

firstAttributeIndex - the index of the 1st dimension to visualize

firstAttributeName - the name of the 1st dimension to visualize

secondAttributeIndex - the index of the 2nd dimension to visualize

secondAttributeName - the name of the 2nd dimension to visualize

Returns:

a 2D XY chart visualizing the clusters found

generatePieChart

public org.jfree.chart.JFreeChart generatePieChart(java.util.List<Cluster> clusters)

Generates a pie chart showing the percentage of points falling into each cluster.

Parameters:

clusters - clusters found by a clustering algorithm

Returns:

a pie chart showing the distribution of points into clusters
