Area Under the Curve Model

The area under the curve is the area between the selected curve segment and the x-axes. The area is calculated using the trapezoidal rule to interpolate the points on the curve according to:

NOTE: This analysis function does not show the integration area on the plot. Check the cursor points on the Label tab in the Function Settings to mark the end points of the integration interval on the curve.

Using This Model

Use the area under the curve to calculate partial areas under a curve.
