I can pull data and produce an OPC UA Server historical tag in a graph, but I cannot with a historical SQL historical tag or polling from a sql query into a perspective chart range selector component. It works with a table. I did try with Document, Float and Integer data types. Is there another way to produce results live?
The components in Perspective are agnostic of the source of the binding that they receive. Also, it’s pertinent to note that the “data” property is king in Perspective. If you can create a binding (regardless of the source) that can conform to the format of the data property that you are attempting to show, that will give you the data you are looking for.
I will also refer you to this page in the documentation as Inductive does a much better job of explaining tag history bindings than I ever could.
Hope this helps!
