52 • Viewing, Printing, Exporting, and Deleting Data in the Data Window
When viewing interval trend data in graph format, you have
several options:
• You can choose which gas you want to graph
• You can choose the zoom level, or displayed time interval,
on the graph. The zoom feature shows greater detail
relative to time. Thus, the length of a time division on the
graph will depend on both the length of the datalogging
session and on the zoom factor. Depending on the length
of the data session, data sessions that show changing
readings will normally have more choices for zoom levels
than sessions that show stable data to allow for viewing of
gas reading changes in greater detail.
• When selected, the Cursor feature allows you to display
the gas reading and log time for each data point saved on
the graph. The number of data points on the graph is
minimized depending on the length of a data session by
several means including omitting consecutive data points
that have the same gas readings. As you use the left and
right arrow buttons on your keyboard to move the cursor
across the graph horizontally, readings at specific log
times are displayed. Use the up and down arrows on the
keyboard to move the readings up or down on the screen.
• If you click the Summary button, the data window will split
into two frames, one above the other, with the graph in the
lower frame and the summary information shown in the
upper frame. The summary information is the same as the
information shown in the lower right frame in Figure 31. To
return to the one frame format, click Summary again.
