Hi all, I am computing area under the curve using "Trapz" function where it takes x and y co-ordinates into consideration. For example, if you consider the attached figure, I am getting the value of shaded area as 296 where it takes into x and y axis values. But I would like to compute only the absolute area ignoring x and y axis values. In this example y axis height is around 7 (-84 to -91) and x axis distance is around 0.1 hence the absolute area would be very small. Any help in this would be highly appreciated.
