For many of the dashboard widgets, you can configure the time period for which the widget displays data. Typical time period options are daily, weekly, and monthly. Follow these steps to configure the time period for a single widget in the current dashboard.
The appliance retains this widget-specific setting for your user account until you change it or unless you change the dashboard-wide time period.
To configure the time period covered by a single widget in the current dashboard:
Click Dashboard and choose the dashboard that contains the widget whose time period you want to change.
Choose the time period for which data is to be displayed.
