To Obtain Min and Max

[tyl]

i am currently using labview 7.0 and working on agilent 4195A. i am working on this programme where i have to locate the min and max point from the graph so as to locate the resonance frequency. but i tried several derivatives but none of them succeed in helping me to locate my min and max. if anyone have any idea, please let me know. thank you.

Hi tyl,

well you are using LV7.1...

I made some comments in your vi - please read the development style guide!
Why don't you use the array min/max operation to get the strongest signal output?

And please provide some test data - nobody here can test your vi without proper hardware, without your signal, with missing subvis...
