Scales, axes, and grids should be used for spatial representations (such as maps) that exceed a display page.
Additional Information:
A scale is a graduated series of demarcations indicating the divisions of an axis. Axes are the graphical representation of orthogonal dimensions in the form of lines (e.g., horizontal and vertical axes). A grid is a network of uniformly spaced horizontal and vertical lines for locating points by means of coordinates. Grids may be applied to large displays to divide them into discrete sections, such as those used in geographical maps. If the grid uses a sequential coordinate system such as numbers or letters, then the user may use the coordinates of the current position to determine how much of the display structure lies in each direction around the current location. Grids are especially compatible with spatially organized information such as maps and mimic displays.
