Creating Contour Plots<br />

Using the Contour Plot Platform<br />

The Contour Plot comm<strong>and</strong> in the Graph menu constructs contours of a response in a rectangular<br />

coordinate system. A contour plot shows a three-dimensional surface in two dimensions. Contours delineate<br />

changes in the third dimension.<br />

Here are some of the options available with the Contour platform:<br />

• specify the number of contour levels<br />

• choose to plot contour lines or filled contours<br />

• show or hide data points<br />

• label contours with response values<br />

• define <strong>and</strong> use a custom coloring scheme<br />
