Connection to MySQL external database with Cornerstone Charts

Hi,

I’ve been using Themeco theme and plugins for a long time now. I’m trying to improve the charts and tables on my website ironwise.app.
Right now, I’m using WPDataTables. I think Cornerstone Charts would be faster and more efficient to load.

My main concern is the connection to the database. WPDataTables is very easy to set up. I just add a separate DB connection by entering the host, user, driver, port and database name + password and I can access the data via queries.

Is there a way to do that with Cornerstone charts ?

I found this post but it seems to be to specific to the use case of the user.

Thanks.
