C-8 Graphics Information
Vertical bar charts
A vertical bar chart formats device data into bars from
bottom to top and varies with time. The command bar
shows the back arrow icon, HART heartbeat or fieldbus
logo, LAS indicator (fieldbus devices only), ScratchPad
application icon, and terminate icon. The tag bar shows
the device type and device tag.
The HELP softkey appears if there is help associated
with the particular selection. Use the buttons to pan,
zoom, and reset the chart. Use the left arrow button on
the 375 Field Communicator or the back arrow icon on
the screen to close the chart view and return to the
previous menu.
Use the drop-down menu to select the variable you want
to display. Additional vertical bars may be present if
more than one variable shares the same axis as the
selected variable. The selected variable from the
drop-down menu appears dark while the other variables
appear light grey. The values, 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.
