This chart helps us visualize peak and low levels in the amount of work over the same seasons of time. If a supplemental line is used for each year, vertical lines may be added to show Percentages. The higher the bar, the more hours were worked. The darker solid portion at the top of each bar shows the amount of overtime that month. Lines running across the bars illustrate the different levels of staffing described by the box on the right.
Solid lines are actual levels.
Dotted lines are projected levels. This format helps us plan vacations and in-depth training events. The values shown on this format is the percent of the annual average in 1994. A value of 100 means that the value is the same as 1994. A value of 200 means that the value doubled.
