                        After all, we’re over 80% most of the time, aren’t we? I can’t tell from this
                        graph. It’s too hard to read.
                          To change the scale, double-click on the Y (i.e., vertical) axis (Fig. 4-47) and
                        change the scale (in this case from 60% to 100%). Now you can start to see the
                        amount of variation from month to month (Fig. 4-48).
