Overview for Simplex Design Plot

Use Simplex Design Plot to visualize the location of types of points in a mixture design and to understand the composition of the corresponding formulations. Minitab plots the design points on triangular axes.

For example, a researcher creates a mixture design to study how the proportions of three ingredients in a household deodorizer affect the acceptance of the product based on scent. The three components are neroli oil, rose oil, and tangerine oil. To help visualize the design space, the researcher creates a simplex design plot.
