"specifies the length of the minor tick marks drawn on the second axis.
The MinTickLen value should be given as a fraction of the minimum dimension of the plotting area. Negative values cause minor tick marks to be placed on the outside of the corresponding grid line or axis (but subject to any clipping imposed by the underlying graphics system), while positive values cause them to be placed on the inside.
The default value is 0.007.
The number of minor tick marks drawn is determined by the Plot
’ s MinTick(axis)
If no axis is specified, (e.g.
" instead of
" ), then a
" operation will affect the attribute value of all the Plot axes,
" operation will use just the MinTickLen(1) value.
