I personally like the time analogy the best, however I do not believe that you have properly dealt with the space analogy in its strongest form. Imagine any of the three axises of space (x, y, or z). Fill in any one axis of space. After you have done so, what does one have. All of space is filled in.

Therefore you could reasonable say that the analogy implies that each dimension represents all of space.
