+When selecting **Network events**, **CloudTrail logs**, or **S3 access logs** as the log type, a detector dashboard is automatically created. The dashboard offers visualizations for the detector and can provide security-related insight into log source data. For more information about visualizations, see [Building data visualizations]({{site.url}}{{site.baseurl}}/dashboards/visualize/viz-index/).

 ## The Findings graph
 
 The findings graph can display findings by log type or rule severity. Use the **Group by** dropdown list to specify either log type or rule severity.
 
 To specify the date range you would like the graph to display, first select the calendar dropdown list. The date selector window opens.

 You can use the **Quick select** settings to specify an exact window of time.
 * Select either **Last** or **Next** in the first dropdown list to set the window of time behind the current setting or ahead of the current setting.
 * Select a number in the second dropdown list to define a value for the range.
 * Select a unit of time in the third dropdown list. Available options are seconds, minutes, hours, days, weeks, months, and years.
-Select the **Apply** button to apply the range of dates to the graph. Information on the graph changes accordingly.

When you use these arrows, the start date and end date appear in the date range field. You can then select each one to set an absolute, relative, or current date and time. For absolute and relative changes, select the **Update** button to apply the changes.

-Each finding in the list includes a finding ID. You can select the ID to open the Finding details pane, which describes the finding by parameters defined when creating the detector.
-The Actions column includes two options for each finding:
-* The diagonal arrow provides another way to open the Findings detail pane.
-* The bell icon allows you to open the Create detector alert trigger pane, where you can quickly set up an alert for the specific finding and modify rules and their conditions as required.
