MinTick(axis) - Density of minor tick marks for a Plot

Description:
This attribute controls the appearance of an annotated coordinate grid (drawn with the astGrid function) by determining the density of minor tick marks which appear between the major axis values of a Plot. It takes a separate value for each physical axis of a Plot so that, for instance, the setting "MinTick(2)=2" specifies the density of minor tick marks along the second axis.

The value supplied should be the number of minor divisions required between each pair of major axis values, this being one more than the number of minor tick marks to be drawn. By default, a value is chosen that depends on the gap between major axis values and the nature of the axis.

Type:
Integer.

Class Applicability:
Plot
All Plots have this attribute.

Notes:
  • If no axis is specified, (e.g. "MinTick" instead of "MinTick(2)"), then a "set" or "clear" operation will affect the attribute value of all the Plot axes, while a "get" or "test" operation will use just the MinTick(1) value.
