Integrating Two Unrelated Values

Hi!

I am trying to integrate two different series that correlate to the same image. I was able to obtain X, Y, and Z values for an image in which the x-values correlate with length, the y-values correlate with width, and the z-values correlate with intensity. However, because these measurements are taken across a rectangular ROI, there are 528 x-values (length) and 504 y-values (width), as the object resembles 1/2 of an ellipse.

I would like the integrate these values so that I can plot (length x width x intensity) for my given shape. I have tried to integrate these values by plotting them on the same scatterplot, however I am not having a lot of sucess. I also am not having any luck finding code that will allow me to integrate these values.

Does anyone know an effective way to integrate two "unrelated" values?
