| CategoryDataset | createCategoryDataset(Comparable[] rowKeys, Comparable[] columnKeys, double[][] data) Creates a CategoryDataset that contains a copy of the data in an array (instances of Double are created to represent the data items). |
| CategoryDataset | createCategoryDataset(Comparable rowKey, KeyedValues rowData) Creates a CategoryDataset by copying the data from the supplied KeyedValues instance. |
| PieDataset | createConsolidatedPieDataset(PieDataset source, Comparable key, double minimumPercent, int minItems) Creates a new pie dataset based on the supplied dataset, but modified by aggregating all the low value items (those whose value is lower than the percentThreshold) into a single item. |
