Use Surface Plot when you have a stored model and want to plot how the fitted response relates to two continuous variables. A surface plot displays the three-dimensional relationship in two dimensions, with the variables on the x- and y-axes, and the response variable (z) represented by a smooth surface.
For example, analysts at a solar energy company want to plot the relationship between heat flux and the positioning of the east and the south focal points. The analysts previously fit a model to describe the relationship between the focal points and heat flux.
This analysis uses a model that you fit and that Minitab automatically stores in your worksheet. For more information, go to Stored model overview.
Use the version of this analysis that corresponds to the type of model you fit.
