Trellis Graphics
Barry J. Everitt, Deepayan Sarkar · Wiley StatsRef: Statistics Reference Online · 2015
Abstract In trellis graphics one, two, or more variables are plotted and conditioned on different values or categories of a given variable (or variables). Component panels representing subsets of the data defined by levels of the conditioning variables are arranged in a single display in a manner that makes comparison easier. Many different types of plots lend themselves to this treatment, including scatterplots and three‐dimensional scatterplots. Trellis graphics help in understanding both the structure of the data and how well proposed models for the data actually fit.
