The scale of 200 is selected because there is no
scale 190. (The nearest bar scale including
190.0 values is selected.)

The scale of 100 is selected because there is no
scale 98. (The nearest bar scale including 98.0
values is selected.)<Caution>・In case of the scale which does not contain 0, such as 10 to 2000, display as the standard bar graph scale
is 0 to 2000.
・In case of unbalanced scales, such as -10 to 0 to 100, display as the standard bar graph scale is -100 to
0 to 100.
Please consult, in case you wish to have bar graph scales other than the above.
