With bowling average forming the X axis and a low number desired and a high Y value indicating a more efficient batting lineup, we can surmise that the top left-hand quadrant denotes the most efficient teams. The opposite is therefore true of the inferior right quadrant.
Finally, the chart indicates that no matter how good a batting attack may be, it's much more beneficial to have butt-kicking bowlers - the most efficient bowlers came from Queensland, who won the Shield. Tasmania had the next most efficient bowling outfit, who ended the season as runners-up. Victoria managed third place.
