Contour Plots

View Multidimensional Relationships in Two Dimensions

The Contour Plot command in the Graph menu constructs contours of a response in a rectangular coordinate system. A contour plot shows a three-dimensional surface in two dimensions. Contours delineate changes in the third dimension.

Here are some of the options available with the Contour platform:

• specify the number of contour levels

• choose to plot contour lines or filled contours

• show or hide data points

• label contours with response values

• define and use a custom coloring scheme
