I imported a DSC or XRD curve, then draw a baseline between the start and end point of a peak, want to get the area among them(the baseline and the given peak),but I failed. what should I do in order to get the area I want? If anyone knows, very helpful and thanks. I need it very much. I use originpro 7.0.
