Show outline: Shows the outline of the grid.

Show grid lines: Shows the vertical and horizontal lines that mark where the grid values are. A grid value exists at each intersection of a vertical and horizontal line.

Show grid ribbon: Turn this on to enable grid ribbon display. This will only apply if a grid has been selected for display from Layer Properties, or from the Grid toolbar.

Line Color: Specifies the color with which to display the grid outline and grid lines.

Interpolate Grids: This option will enable bi-cubic spline interpolation resulting in a much smoother appearance for the grid. However, in regions of large discontinuity (e.g. fault edges) artifacting is likely to occur, resulting in grids with an inferior overall appearance. The higher this setting is (e.g. super fine), the slower the map will redraw, the larger the output hard copy file will be, and the longer it will take to print.
