Group Security Categories
When Group Security Categories is unchecked, the selected security categories are shown individually on the Activity graph. This enables you to view which categories had more activity within the given time frame or where spikes in some categories occurred. Clicking the category name on the graph or in the Security Categories filter will show or hide that category's events on the graph.
Rolling over a point on the line graph provides a summary of the security events at that time by the categories selected. Clicking the details redirects you to the Activity Search report where you can further view the activity's details.
