Options Description
Backward
Marker The backward marker of a bar graph can have up 12 marks. The actual number of marks and the
value of each mark are specified at runtime by the backward marker control block. The position of
a mark is determined by the value of that mark. The color of a mark is determined by the
comparison result between the monitored value and the value of that mark.
Select and set this option in the B. Marker page.
Range Display You can specify a low limit and a high limit for a bar graph. The limits can be constants or
variables. At runtime, when the monitored value is equal to or below the low limit, the bar graph
shows the bar with the FG color and the BG color set for the low limit. When the monitored value is
equal to or over the high limit, the bar graph shows the bar with the FG color and the BG color set
for the high limit.
Select and set this option in the Advanced page.
Percentage
Display A bar graph can show the percentage of the current bar length versus the full bar length.
Select and set this option in the Advanced page.
Visibility Control A bar graph can be shown or hidden either by a specified bit or by the current user level. Select
and set this option in the Visibility page.
Low Limit = 20
High Limit = 80
Low BG Color = Light Blue
