The switch_axes command shows, hides or toggles the coordinate axes on the graphics screen depending on whether the argument is 1, 0 or empty. (This can also be controlled by a show axes checkbox in the configuration panel brought up with the cfg button on the graphic screen control panel.)
toggles whether or not the coordinate axes are shown in subsequent
graphic screens. Rather than toggling,
causes all later graphic screens to have the axes, and
causes all later graphic screens to omit the axes.
When the axes are visible, they have tick marks whose separation is determined by the X-tick and Y-tick values on the graphic configuration screen. Setting these values to 0 removes the axes.
