5.6.5.5 Area Under Curve
The Area Under Curve feature calculates the area under the curve above a certain threshold for specific graph segments.
Calculations can be viewed in the Event Summary.
Before using this feature, the Area Start and Area End events need to be configured for calculation start and end points.
Area Start and Area End events configured using control panel buttons can only be used while a test is running, while the
events added to the Event Annotation box can be used while a test is running or after a test is stopped or saved.
To configure Area Start and Area End buttons in the control panel:
1. Click Options > Control Panel Settings to open the
control panel configuration window.
Figure 65: Command Box
2. In the Command box, configure the Area Start* and Area
End
buttons.
* The
Area Start
button is set with the format
AS: pressure
channel : threshold value .
In this example:
AS:Pves:0
means
that the area under the Pves curve above a threshold of 0 will
be calculated (
Figure 65).
3. Click
OK
to add the buttons to the control panel.
Refer to the Control Panel Settings section on page 71
for
more information on configuring the control panel.

button on the control panel to open the Event
Annotation box.
3. Create the
Area Start
event by typing the format
AS: pressure
channel : threshold value.
In this example AS:Pves:0 means
that the area under the Pves curve above a threshold of 0
will be calculated (
Figure 66).
4. Click
