About Graph Display
If a selected line’s data reading is a number (such as
14.4 V, 1.1 V, or 23 Amps), you can use the Graph func-
tion key to display the line’s data as a graph. For
example, see Figure 3.7
and Figure 3.8. Notice how the
function key changes to Analog so you can change the
display to Analog (see the next section).
Note: The function key toggles from Graph to Analog to
Digital and back to Graph.

Figure 3.8: Datastream Screen - Graph Display
The graph has a past activity section and a magnified
live activity window. The minimum and maximum mea-
surements appear to the right of the graph and the
digital reading is below the graph. You can use the Left
and Right Direction keys to move the magnified window
through the data. See “Freeze Frame
” on page 25.
About Analog Display
When a selected line’s data reading is displayed as a
graph (seeFigure 3.8
), you can use the Analog function
key to display the line’s data as an Analog gauge at the
top of the screen (see Figure 3.9
). When you display
the gauge, the Digital data line remains displayed in its
normal position in the list. Also, the function key
changes from Analog to Digital so you can change the
display to back to Digital only.
You can display up to three gauges at the top of the
screen. When gauges are displayed, you can tempo-
rarily “hide” them. For details, refer to “Show / Hide
Analog” on page 30.
