Contour Profiler
Contour Profiler
The Contour Profiler shows response contours for two factors at a time. The interactive contour profiling
facility is useful for optimizing response surfaces graphically. Figure 24.26 shows an example of the Contour
Profiler for the Tiretread sample data.

• There are slider controls and edit fields for both the X and Y variables.
• The Current X values generate the Current Y values. The Current X location is shown by the crosshair
lines on the graph. The Current Y values are shown by the small red lines in the slider control.
• The other lines on the graph are the contours for the responses set by the Y slider controls or by entering
values in the Contour column. There is a separately colored contour for each response (4 in this
example).
• You can enter low and high limits to the responses, which results in a shaded region. To set the limits,
you can click and drag from the side zones of the Y sliders or enter values in the Lo Limit or Hi Limit
columns. If a response column’s Spec Limits column property has values for Lower Spec Limit or Upper
Spec Limit, those values are used as the initial values for Lo Limit and Hi Limit.
