Selecting traces
In the Graphing Options panel, use the Navigation tab to select all the traces you wish to display
in the top (navigation) window and the Detailed tab to select all the traces you wish to display in
the bottom (detailed) window.
Displaying high rate data
The split screen facilitates the display of high rate data, allowing the user to zoom in and out,
according to the time period selected. Two bright blue vertical lines in the navigation window
track the time period displayed in the detailed data window, while the vertical red line in the
detailed data window provides a point of reference.
Set the time period displayed
Use the Detailed tab View drop-down to set a time period between 10 seconds and 24 hours
for each half of the split screen. The split screen is designed to display a shorter time period in
the detailed data window, zooming in on a segment of the total time period displayed in the
navigation window.
Navigation
Use the scroll bar at the bottom of each window to navigate horizontally through the data. The
data displayed in the detailed data window can be more easily navigated using the navigation
window. To select or change the specific period of time you wish to display in the detailed data
window, click in the navigation window at the point you wish to zoom in on.
