Axes extend the entire length of the graph scale along each axis. Tick marks provide reference for points on a scale. Each tick mark represents a specified number of units on a continuous scale, or the value of a category on a categorical scale.
Use the NMINOR subcommand to include one or more minor tick marks between consecutive major tick marks.
For example, to display one minor tick mark between consecutive major tick marks on the x-axis of a scatterplot, use:
Plot C1 * C2; Scale 1; LDisplay 1 1 1 1; NMinor 1.
