Aabel provides both simple graphs and matrices of mosaic and parquet diagrams, along with easy to use tools for customizing the diagrams. The mosaic plot is a graphical method for visualizing n x m contingency tables. The areas of the mosaic tiles are proportional to the observed frequency of groups in the contingency table. In a parquet plot, the area of each tile is proportional to the expected frequency of groups in the contingency table. In Aabel, the diagram tiles can be color coded using:
For identifying categories with missing data, you can color rows or columns of tiles by category. |
