When VIEW is pressed, the Data Graph window appears,
The Data Graph window presents the transferred data in an x‐y graph format with Date/Time
represented on the horizontal axis and Temperature / Relative Humidity / Dew Point / Grains per
pound GPP (with optional RHT10‐SW only) / Alarm Limits represented on the vertical axis:
To zoom in and out of data regions, there are several approaches:
1. Use the mouse to click and drag a box around any data area to magnify the selected
area.
2. Click on the zoom magnifier icon tool on the menu bar
3. Select VIEW ALL or ZOOM OUT 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 RH and Dew Point are represented by the solid yellow and green lines,
respectively. The low and high alarm values for temperature are represented by the dashed red
traces; the corresponding alarms for humidity are represented by the dashed yellow traces.
