Description
Display direction
The bar graph can be displayed vertically or horizontally.
Reference position When the bar graph is displayed horizontally, the starting point of the bar
(reference position) can be set to standard (Left or right end of the scale,
whichever the value is smaller) or the center.
Display color
The displayed color of bar graphs can be specified for each channel. The
display color is common to the trend display color.
Scale display
Main scale marks are displayed for each channel. You can select the number
of divisions created by the main scale marks from 4 to 12. This is common
with the number of scale divisions of the trend display.
