Hi there,

I am wondering if it is possible to calculate the area under the fitted curve and also find out the centroid of the curve, i am dealing with both linear and non-linear fittings. thanks in advance!

Hi Mike,

I suggest you can use Integrate Gadget to calculate the area and output the centroid of the curve.

Plesae refer to this online help page and the video:
