Use a simplex design plot to visualize the mixture design space, or a portion of the design space if you have more than three components. Minitab plots the design points on triangular axes. For more information, go to What the triangular coordinate system shows.
The display depends on whether the design contains process variables or an amount variable, and how you choose to handle these variables. If your mixture design contains process variables or an amount variable, you can display a single plot or you can display all the levels of these variables. To see an example that displays multiple levels of a process variable, go to Example of Simplex Design Plot.
Hover the pointer over a design point to see the settings and the row number in the worksheet that are associated with that design point.
