The dashboard viewer is a control that can be added to the My Vault portal that will allow users to view a form dashboard from the portal view.
Once the control is added in the layout designer, you can select from the following options to configure
Select the form dashboard to display.
Select the number of rows for the viewer. You can set a fixed amount or use the user's preferences.
Check Display Menu Bar if you want the standard form dashboard menus to be visible.
If the user does not have at least viewer permissions to the dashboard the data will not be available to the user.
