Use the Evaluation > Integrate Curve command to calculate the integral of the active curve.
A new curve is created according to the following formula:
y(n)’ = { y(n) * { x(n) - x(n-1) } } + y(n-1)
x(n)’ = x(n)
where n = 1,2,3....
Integrated curves are identified by (Int).
Use the Scaling > Optimize Graph command to optimally scale the new curve.
You can integrate curves that have already been integrated and then recieve high-order integrals. Please note that direct recording of higher-order integrals is not possible. Such curves are automatically removed when recording starts or during channel selection.
