The trend chart displays aggregated values for all of the queries submitted by the selected user or application. You can choose a daily or weekly aggregation period. You can view a time frame of the last six months, the last year, or the last two years. You can choose to display vertical lines indicating the date of ruleset and version changes using the check boxes on the upper right. Application version is recorded when a query is logged with the "version" query band.
Configured charts are shared among all similar views. For example, if you drill down into a user and set up the chart in the Trends tab, the Trends tab for applications will have the same configuration.
By default, one chart is displayed. You can add and remove charts.
