When a user creates a Dashboard, the panel displays on the Home page or the Dashboards page. If for some reason the Dashboard does not update automatically, users can manually refresh it. This solution outlines steps to refresh a Dashboard panel.
With the desired panel open, click the Refresh button in the top right of the Dashboard page.
Beginning in version 7.94+, users have the option to configure an automatic refresh internal on the panel properties. The value entered in the automatic refresh internval field must be a whole number - no decimals are allowed in this field.
