peak dispatcher tasks, and the current active and peak active user
transactions, over a number of intervals. If enough intervals are
available, the chart shows a maximum of 12 intervals: six before and
five after the selected interval. Each interval is shown as a separate
column in the chart, and shows the time, interval number, and current
number of dispatcher tasks. The column for the currently selected
interval is shaded. The points on the chart provide an indication
of the value, not an actual value. To see the actual values for an
interval, hover over a column to display a tooltip that shows actual
values.

transactions during the selected interval. You can click the columns
