There will be at least one point where they intersect. There might be several of these points and in fact all the points of intersection can form a curve. Now in theory, the halacha might be anywhere in which all three intersect. However I suggest that there will be a cusp point where all three functions are maximized.
But now that we have come this far I want to go further and suggest that these three axis are not enough to accommodate all values. (See the polynomic theory of value.) In practice you want each value to have its own axis and then to maximize the function. E.g. you want the God axis to be the z axis and justice to be the y one and beauty the x axis and so on for other modes of value.
