The horizontal axis shows the time; relationships positioned towards the leftmost area of a diagram occurred at the start of the data interval considered, and those at the rightmost end occurred at the end of the data interval considered.

Lower bands would be of interest to investors with short term horizons, whereas higher bands would be of interest to investors with longer term horizons.
