Thread: Determining an area from an image profile plot

Dear all I have a graph which is that a of a profile plot. I would like to quantify a certain region of my graph and I want to come up with a formula for it.

Any suggestions will help . I am attaching an image and in red is the area i want to come up with an equation for. The graph is intensity vs displacment.

Hey wmapg05.

Are you familiar with finding areas with calculus (both analytic and numerical)?
