Categorized Graphs (also, Trellis Graphs)

With this type of graph, you can categorize 2D, 3D, or nD plots by the specified categories of a selected variable. One component graph is produced for each level of the grouping variable (or user-defined subset of data) and all the component graphs are arranged in one display to allow for comparisons between the subsets of data (categories). For a detailed discussion of categorized graphs, see Categorized Graphs; see also Data Mining.
