This tab contains 2 sections:

    • Tics format: defines the line size, color and style of the grid lines (both X and Y axis). 

    • Tics length: defines the length of the X axis and Y axis grid lines at both sides of the axis. Values should be between 0 and 50%. Default value is 50%, meaning that for both axes, the grid lines are drawn from one axis side to halfway the other axis side. Since this is done for both axis sides, the grid lines then span the full interior window height and width.
