Under each period column you will see the loading for each operation.
You can click this column heading to only show the operations that actually have loading for that particular period. You can also do this using the Info menu which appears if you right-click in the chart, by selecting the row of your choice under the period column and selecting the option called Only this period’s loading. The loading for each period is also displayed as a total under this column.
If you have selected the Show/hide capacity alternative under the Info menu, you will also see the work center’s capacity for each period above the period column. The two rows Difference and Accumulated Difference will then also appear at the very bottom under the period column. (See the explanation below).
Difference
The difference between the capacity and the loading for each period.
Accumulated Difference
The accumulated difference means that the previous period's difference is added to the next period's difference. You can also add the lag data to this value by selecting the Show accumulated difference including lag option in the Info menu when you right-click in the list.
