The Surface Plot Control Panel
For the tire tread data, one might set the hardness at a fixed minimum setting and the elongation at a fixed
maximum setting, then use the slider for modulus to see which values of modulus are inside the limits set by
the other two surfaces.
The Surface Plot Control Panel
The drop-down menu in the main Surface Plot title bar has three entries.

Script contains options that are available to all platforms. See Using JMP.
The Control Panel consists of the following groups of options.
Appearance Controls
The first set of controls allows you to specify the overall appearance of the surface plot.
Sheet, points
is the setting for displaying sheets, points, and lines.
Isosurface changes the display to show isosurfaces, described in “Isosurfaces” on page 542.
Show formula shows the formula edit box, allowing you to enter a formula to be plotted.
The Resolution slider affects how many points are evaluated for a formula. Too coarse a resolution means a
function with a sharp change might not be represented very well, but setting the resolution high makes
evaluating and displaying the surface slower.
Appearance Controls for Other Platforms
If you select the Surface Profiler from the Fit Model, Nonlinear, Gaussian Process, or Neural platforms,
there is an additional option in the Appearance controls called data points are. Choose from the following:
Off
Turns the data points off.
Surface plus Residual
Shows the difference between the predicted value and actual value on the surface.
Actual
Shows the actual data points.
Residual
Shows the residual values (if they are not off the plot).
