Measuring Slope of peak on Excel graph Lionel Lin 12/31/2008 11:52:04 AM I have a graph with many peaks which are decreasing and increasing and i need to get the slope of these peaks ignoring the rest which is below these peaks. My graph has many peaks e.g. 50 peaks, each one. What i am trying to do is draw a line through the top of two peaks and then get the slope of this line. Any suggestions?
