creating a graph by subtracting successive array elements in labview

[Gaurav garg]

I have an array 'A1' of 'N' elements. I want to create an  array 'A2' of 'N-1' size having first element as A1[1] - A1[0], 2nd element as A1[2] - A1[1], and so on .

then I want to  plot the A2 array on the graph for analysis.

i.e i want to subtract the successive elements in an array and plot a graph of the subtracted values. 

please help me 

Thanks in advance.

Use Array subset with 1 as index/offset, wire both arrays to a '-' and the result is an array with a[1]-a[0],a[2]-a[1] and so on.
