Grids
You can provide the surface of the 2D diagram or the coordinates planes of the 3D diagram with a grid to increase the legibility of the diagram. The location of the grid lines is oriented toward the divisions and subdivisions of the axes spanning the plane. Since 2D diagrams can have any number of X and Y axes, each axis can be set separately, whether or not the grid lines are to be drawn for their divisions.
You can separately style the horizontal and vertical lines as well as the frame and the grid background. The frame and background are part of the grid in 2D diagrams only, since here the axes do not have to be positioned on the edges. In 3D diagrams, the framing of the planes as well as their background color are part of the axis system.
