The Columns represent the total events for a time period, typically a day. However, the time
periods shown by the columns at the start and end of the chart are segmented to add up to 24
hours based on the time the report was displayed. For example, in
left represents the event count for 10/22/2010 starting at 2:45:53 PM, while the column on the right
represents the event count for 10/29/2010 ending at 2:45:53 PM. At the top of the window, the
generation time for the report is displayed.
Hovering the mouse over a column displays the total event count and the event count change
from the prior time period. The text boxes displaying this information are bordered in green if the
event count increased and in red if the event count decreased.
The teal horizontal line represents the average event count over the period and the vertical blue
line represents the moving average. You can change the number of days used for the moving
average by clicking on the up or down arrows next to the Days in Moving Average field.
