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.
Activated X and Y Grids
