Events by Event Group, Events by Score, and so on. You can display the Top N report window by

Defining a Top N Report
The default TopN report displayed is a column chart of the top 10 Events by Event Group , as
shown in Figure 4-1 . You can change the type of report to display by selecting from a drop down
list at the top of the report window, as shown in Figure 4-2 on page 4-3. Table 4-1 on page 4-3
describes the Top N reports.
You can interactively change the number of occurrences charted by increasing or decreasing the
number in the
Top field at the top of the chart.
Filter the data further by selecting an existing filter from the Filter drop down list, or by creating a
new filter, as described in “ Creating and Editing Report Filters ” on page 1-10.
