Let's say you have a picture of two overlapping graphs. You don't have the equations that generated them. but you know the graphs is relatively accurate. for example, http://pg.photos.yahoo.com/ph/sean_incali/detail?.dir=/9264&.dnm=191b.jpg&.src=ph Now... let's say you wanted to find the area under curve for both curves (blue and green) between certain x values... for example, 425nm <= x <= 475nm , and then 500nm <= x <= 550nm, and then 525nm <= x <= 575nm. is this doable in Mathematica? thanks In advance for any thoughts. sean
