Ticklen Keyword

Used With Routines: AXIS, BAR3D, BOXPLOT, CONTOUR, CONTOURFS,  CONTOUR2, OPLOT, PLOT, SHADE_SURF, SHADE_SURF_IRR, 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.
