FITLOW= lower bar in charts = 0, none

Use FITLOW= to position the lower acceptance bars in Tables like 6.2. Use FITHIGH= to position the higher bar.

 

FITLOW=0 cancels the instruction.

 

Example: We want the lower mean-square acceptance bar to be shown at 0.6

 FITLOW=0.6 ; show lower fit bar

CHART=YES ; produce Tables like 6.2
