Diagram Configuration

You can set the Grid Style to one of four options:

None: No gridlines are drawn on the plot area
Lines: Straight lines form a grid of squares on the plot area.
Crosses: Crosses are drawn to indicate points where x and y have integer values (e.g., (1,1), (4,2) etc.).
Polar: Lines of constant radius and of constant angle are drawn on the plot area.

Other options for the diagram appearance can also be configured:

Axis width:: Sets the width of the lines representing the axes.
Line width:: Sets the width of the lines used for drawing the grid.
Tic width:: Sets the width of the lines representing tics on the axes.
Tic length:: Sets the length of the lines representing tics on the axes.
Show labels: If checked, the names (x, y) of the axes are shown on the plot and the axes' tics are labeled.
Show axes: If checked, the axes are visible.
Show arrows: If checked, the axes are displayed with arrows at their ends.
