SURFACE Corresponding System Variable: !P.Ticklen Controls the length of the axis tick marks, expressed as a fraction of the window size. The default value is 0.02. Ticklen of 0.5 produces a grid, while a negative Ticklen makes tick marks that extend outside the plot region, rather than inwards.
Example
To produce outward-going tick marks of the normal length:
PLOT, X, Y, Ticklen = -0.02
To provide a new default tick length, set the system variable !P.Ticklen.
