Use a 3D surface plot to see how a response variable relates to two predictor variables. A 3D surface plot is a three-dimensional graph that is useful for investigating desirable response values and operating conditions.
The peaks and valleys correspond with combinations of x and y that produce local maxima or minima. Minitab uses interpolation to create the surface area between the data points. For more information, go to Mesh.
Rotate the graph to view the surface from different angles. Adjust light settings to better visualize the peaks and valleys of the surface. For more information, go to Select display options for 3D Scatterplot and 3D Surface Plot.
