MTICK= measure distance between tick marks on plots = 0, auto-size

Specifies the measurement distance between tick marks in Tables 1, 2, 3.2, 4, 5, 8, 9, 12, 16, and more. This is in logits, unless USCALE= is specified, in which case it must be specified in the new units defined by USCALE=. To customize particular tables, use the Specification pull-down menu. See MTOP=

 

Example 1: You want the vertical range on the Table 2.2 map to be -6 to +6 logits with tick marks every 2 logits:
MRANGE=6

MTICK=2

 

-6       -4        -2         0         2         4         6
