Hi Chris,
The data source of my summary widget that displays "No Data" message is an Oracle View table (Oracle 11g) that I published in one of my on-premise map services. I added the service URL of view table as an external data source in Operations Dashboard to be able to use it in the Summary widget. Unfortunately, you will not be able to access my on-premise map services. So, as an alternatively I attached here the screen shots of the widgets panel my Operation Views both in Windows and Browser versions.
The photo on the right is OpDashboard-browser version while the photo on the left is the Windows version of the OpDashboard. I think it is important to take note that the two widgets (Summary and Bar) have the same data source (Oracle View Table) and the bar widget works fine in both versions of OpDashboard.
(Browser Version) (Windows Version)
Thanks,
Karen
