hi monks, I am trying to write a program which basically reads in an excel file containing the coordinates of a graph. I am then trying to get the values corresponding to the peak of the graph. So far my program can do this for any given coordinate. However, how can I calculate the peak value on a graph if I do not know the coordinates of it??? The graphs I'm dealing with look like the ones below. If the '*' at the peak of the graph wasn't there how would I decipher the x-axis value for it?? thanks..
