Interesting Problem on a Graph

[TITAN-x]

Sorry GerdW, I didn't get why did you include 8000 in the index sub array functions? What did you mean with that?

Hi N.,

I didn't get why did you include 8000 in the index sub array functions? What did you mean with that?

"limit the range of your data to interesting parts"

The other approach using a running mean/stdev is attached…

Okay, I will try and update you GerdW. Thanks for your help.

Hi N.,

notice the edit I made to my last post…

Yes, yes I noticed it...  If I would change the amplitude scale of the graph you plotted in the second example that is starting 0 to 0.175 to my acualt values than I was done. Now I will try to adopt the second plot to the actual amplitude values in my original graph.

Hi N.,

in the second VI you get just the peak position (X index), with this index you can read the Y values from your original data!

(Keep in mind the phase shift you get from the PtByPt function…)
