Specify the options for Factorial Plots for mixture designs

Stat > DOE > Mixture > Factorial Plots > Setup > Options

Add your own title to the plot. For an interaction plot, you can also specify how to display the plot.

Draw full interaction plot matrix

Select to display the full interaction matrix when you specify more than two process variables instead of displaying only the upper right portion of the matrix. In the full matrix, Minitab displays the transpose of each plot so that you can see each variable displayed on the x-axis and on the legend. If the two variables interact, you can look at either plot to see the interaction. However, sometimes you can identify interactions more easily when you examine both plots.
