Use Contour
Plot when you have a stored model and want to plot the relationship between a fitted response and two continuous variables. A contour plot displays a twodimensional view in which points that have the same response value are connected to produce contour lines.
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.

When to use an alternate analysis
 If you do not have a stored model, use Contour
Plot in the Graph menu to plot the data means instead of the fitted means. For more information about the types of means, go to Data and fitted means.
 If you have a stored model and want to predict the value of the response variable for combinations of variable settings that you specify, use Predict.
 If you have a stored model and want to plot the main effects and interaction effects with fitted means, use Factorial
Plots.
 If you have a stored model and want to plot the relationship between a fitted response and two continuous variables with a threedimensional response surface, use Surface Plot.
 If you have at least one stored model and want to identify an area where the predicted means of one or more response variables are in an acceptable range, use Overlaid Contour
Plot.
 If you have at least one stored model and want to find values that optimize one or more responses, use Response
Optimizer.
