DATA GRAPH

The Data Graph window presents the transferred data in x-y graph format with Date/Time represented on the

horizontal axis and Temperature / %Relative Humidity / Dew Point / Alarm Limits represented on the y axis:

To zoom in and zoom out data regions, there are several approaches, these are:

1.

Use the mouse to click and drag a box around any data area to magnify the area selected.

2.

Click on the zoom magnifier icon tool on the menu bar

3.

Select ZOOM OUT / ZOOM IN from the VIEW pull-down menu.

In the example graph above, the Temperature is represented by the solid red line (the lines are known as ‘traces’),

the Relative Humidity % by the solid yellow trace, and the Dew Point Temperature by the solid green trace. The

low and high alarm values for temperature are represented by the dashed red trace, the low and high alarm values

for Relative Humidity by the dashed yellow trace.

To customize the graph window select SHOW TRACES, BACKGROUND, GRID LINES, and MASK POINTS from

the VIEW pull-down menu. These options provide the following features:

SHOW TRACES: Allows the user to select which data to view as a trace (Temperature, RH, Dew Point, & Alarms).

BACKGROUND: Select background color scheme.

GRID LINES: Add or remove grid lines from x and y axes.

MASK POINTS: Places dots on the traces for the actual data points, breaking up the continuous nature of a trace.
