Display XY Plots and Events table data in Notifications embedded PI Vision screenshot
When Notifications e-mails are configured to include a screenshot of a PI Vision display, the screenshot will show blanks where the data should appear. This is due to a limitation of Phantom JS, the browser used to render the screenshots, which does not support Negotiate (Kerberos/NTLM) for authentication. XY Plot and Events table data require Kerberos authentication since they are supplied by PI Web API. This can also happen with other PI Vision symbols if Negotiate is the only provider listed in IIS for Windows authentication.
PI Server 2018 SP3 Patch 2 was released yesterday. It includes an update to Notifications that corrects the screenshot issue with PI Vision 2019.

Except that screenshot notifications don't work at all in PI Vision 2019.
It looks like a case of 1 step forward, 10 steps backward on this one?

This will no longer be a problem after the PI Vision 2019 release. The XY Plot and Events Table symbols have been updated to use the same type of data access as the rest of PI Vision.
