Origin Ver. and Service Release (Select Help-->About Origin): Origin8
Operating System: Windows XP

How do I go about finding the apex of a specific curve within a graph. The graph that I plotted has multiple curves...and there are 2 specific curves that I need to find the apex of with respect to the x-axis. How do I go about doing this?

Thanks from a tired PSU lab rat...

To find a derivative,
1) go Menu/Data --> choose one of your curves
2) go Analysis/Mathematics/Differentiate

There are also more sophisticated tools to work with peaks...
