Finding The Area of A XY-Graph

[Rayderon]

I have obtained several plots of graphs but i cant figure out how to get the areas of those plots (The plots are shown in the attachment). Is there anyway in labview that i can get those areas?

If you reduce the shape to a polygon, you can use the formula:

Area = (1/2) Sum [i=0 -> N-1] (xi*yi+1) - (xi+1*yi)

LV 7 Example attached ( a polygon of 2 triangles)
