Gauge Charts
A gauge chart formats device data into a view similar to an analog car speedometer
and plots device data varying with time. Use the drop-down list to select the variable
you want to highlight. Additional gauge needles may be present if more than one
variable is defined for the option selected in the drop-down list. The selected variable
from the drop-down list appears as a long, colored needle while the other variables
appear as short, colored needles. The colors displayed are determined by the device
description and may vary between devices.There can only be a maximum number of
three variables per gauge chart. The labels and axis displayed are determined by the
device manufacturer.
The chart update rate is determined by the device manufacturer. The default chart
update rate is 1 second.

Graphs
A graph is a snapshot line drawing of device information. Use the drop-down list to
select the variable you want to highlight. Additional variables may be present if more
than one is defined for the option selected in the drop-down list. The selected variable
from the drop-down list appears as a bold, solid colored line while the other variables
with the same Y-axis appear as thin colored lines. The colors displayed are determined
by the device description and may vary between devices. Variables that do not share
the same Y-axis as the selected variable appear as dashed, colored lines. The labels
and axis displayed are determined by the device manufacturer.
