You can use a simplex design plot to visualize the mixture design space (or a slice of the design space if you have more than three components). Minitab plots the design points on triangular axes. You can plot the following:
Components
Select a triplet of components for a single plot: Choose to plot three components.
X-Axis: Choose a component to display on the x-axis.
Y-Axis: Choose a component to display on the y-axis.
Z-Axis: Choose a component to display on the z-axis.
Select four components for a matrix plot: Choose to display four simplex design plots in a single page layout. Then choose four components from the drop-down list.
Generate plots for all triplets of components: Choose to generate plots for all triplets of components, each in a separate window.
Component Unit in Plot(s)
Amount: Choose to display the components in amounts.
Proportion: Choose to display the components in proportions.
Pseudocomponent: Choose to display the components in pseudocomponents.
Point Labels
None: Choose to suppress display of point labels.
Run Order: Choose to use the run order for the point labels.
Replicates: Choose to use the number of times a point is replicated for the point labels.
Point Type: Choose to use the point type for the point labels.
Include process variables: Choose to display a simplex design plot for each level of a process variable.
Plot all level combinations: Choose to display single simplex design plot and include all the levels of the process variables in a single layout.
Include mixture amount variable: Choose to include an amount variable. By default, Minitab will plot the amount variable at its first defined value.
Plot all mixture amounts: Choose to display a single simplex design plot include all the levels of the amount variable in a single layout.
