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.
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:
Variables Controls
When there are more than two independent variables, you can select which two are displayed on the x- and y-axes using the radio buttons in this panel. The sliders and text boxes set the current values of each variable, which is most important for the variables that are not displayed on the axes. In essence, the plot shows the three-dimensional slice of the surface at the value shown in the text box. Move the slider to see different slices.
Lock Z Scale locks the z-axis to its current values. This is useful when moving the sliders that are not on an axis.
Grid check boxes activate a grid that is parallel to each axis. The sliders enable you to adjust the placement of each grid. The resolution of each grid can be controlled by adjusting axis settings. For example, Activated X and Y Grids shows a surface with the X and Y grids activated.

The dependent variables controls change depending on whether you have selected Sheet, points or Isosurface in the Appearance Controls.
Dependent Variable Controls
Menus appear after you have selected a Point Response Column. The style menu lets you choose how those points are displayed, as Points, Needles, a Mesh, Surface, or Off (not at all). Points shows individual points, which change according to the color and marker settings of the row in the data table. Needles draws lines from the x-y plane to the points, or, if a surface is also plotted, connects the surface to the points. Mesh connects the points into a triangular mesh. Surface overlays a smooth, reflective surface on the points.
Enables you to show or hide the top or bottom of a surface. If Above only or Below only is selected, the opposite side of the surface is darkened.
Most of the controls for Isosurface are identical to those of Sheet, points. Dependent Variable Controls for Isosurfaces shows the default controls, illustrating the slightly different presentation.
