Graphics Information
C-5
Charts Charts let the device descriptions display a graphic view
of variables as they occur over time. There are four
major types of charts:
• Strip/sweep/scope - Displays variable data with an
x-axis of time.
A strip chart continually updates the chart, scrolling
from right to left.
A scope/sweep chart paints the screen from left to
right, and then paints the screen from left to right
again, overwriting the oldest data.
• Horizontal bar - Displays data represented as bars
from left to right.
• Vertical bar - Displays data represented as bars from
bottom to top.
• Gauge - Displays a gauge chart, similar to an analog
car speedometer.
NOTE
If a chart is displayed for an extended time period, the
375 Field Communicator will have decreased response
time due to the large number of data points in the chart.
