Hi, Data used by DataTool is basically a polygonal curve made of a collection of points ([i],y[i]). Hence, the area is computed basically by adding up the area of each vertical polygon between x[i] and x[i+1]. If your question was related to whether DataTool used any integration algorithm (such as Simpson's rule)... no, it just uses a polygonal approximation. Paco
