Please upload your VI along with saved data, or if you're reading the data from a file then please upload your file.

Hi limatorek,

The problem is that the first element in the array you are trying to integrate it "NaN," or "Not a Number."  Having this number in your array is causing the integral to always be NaN.

I believe that the the first element is becoming NaN because you are subtracting 4 from your array index prior to the array having 4 elements in it.  You are basically going out of the range of the array (trying to acess the -4 element) and this is causing the average function to result in NaN.

Hope this helps!
