ColumnCorrelationMatrix (Macrofocus MOLAP API for Swing SpecificationMOLAP is a Multidimensional, Open-Source, In-Memory, Object-Oriented, and Embeddable API for aggregating datathrough computationally efficient multidimensional cubes developed by Macrofocus. It supports the usualdrill-down, drill-up, slicing, dicing, and pivot operations, alongside a wide choice of built-inaggregation functions, with many additional distinctive features.A good and efficient starting point is the use of the {@link com.macrofocus.molap.dataframe.DataFrameFactory} class. It will get you started within minutes!)
