Do you have access to the data the graphs are based on? Or are you
talking about trying to analyze the shape of a curve (bitmapped or
otherwise)? The two problems will have quite different approaches.

I have a very large number of graphs to crunch through to find local
minima and maxima. The data is regularly spaced, which eliminated
one problem. I know too that the window value used has to be an
adjustable variable as peak and trough significance may need to be
found for a wide range of time periods within the data set.
I had thought of using a moving average to find a slope of zero and
then use an offset function to find the peak and trough in time.
I've used stackoverflow to have a look and apparently the problem is
a lot less trivial than I thought.
Any suggestions for fitting to a function, using the graphing
functions in rev, etc would be most welcome.
