Charting Database and Tag History data together in Perspective

Ignition

I have a client that has an existing system using Vision in Ignition 7.9 they have a page that uses an EasyChart to display data using both Tag History pens and Database pens. We are building a new system for them using Perspective in Ignition 8.1 and they would like a similar data display of some tag history data and some database data. I looked at using a PowerChart but those only have Tag History pens. Does anyone know a way to display Database data and Tag History data in one chart in Perspective?

Ignition 8.1 introduced a new read-only history provider explicitly for this purpose:

It makes what Vision would call a DB pen usable in Perspective.

Thanks.
