how to find the lowest point on the data or cusp location?

[HOLYFIELD]

Hey i am fairly new to lab view and have a vi system that graphs my aquired data. now im stuck....i need to create a vi  the locates the lowest point in my graph/ cusp value.

heres a picture of the graph.

Run the data through an array min max and use the index of the min to position your cursor.

ok i will try it and see if it works.

with the min max array vi. can i set a threshold to locate the lowest/smallest amplitude in the graph?

[HOLYFIELD]

heres how i have it set up. but im not getting a graph. for the location.

ok i think i got it. i have it now telling me what the lowest point of the array is. is there a way to graph the wave from from this point for a few blocks?
