Display factorial plots to illustrate main effects and interaction effects.
Main effects plot: Check to display a main effects plot.
Interaction plot: Check to display an interaction plot. This plot creates a single interaction plot for two variables, or a matrix of interaction plots for three or more variables. You must have 2 or more variables to use this plot.
Display lower left matrix: Choose to display one plot for each pair of variables.
Display full interaction matrix: Choose to display both plots for each pair of variables, such as Variable 1 by Variable 2 and Variable 2 by Variable 1. Sometimes you can identify interactions more easily when you examine both plots.
