public class Grid
extends AbstractGrid

Draws a grid, based on the axis mapper(s). Grid color is set as a foreground color, fill color is set as background color using PaintStyle object. You can set rendering hints and composite using BrushStyle object. Drawing outline can be enabled if grid is not drawn, but the background is filled with some color.

If spacing between grid lines becomes less than 6 pixels the grid lines won't be drawn. This feature is to prevent grid lines drawing when they are too close.
