I have a time series chart with the data having a binding set up as shown below to Tag History. If I open the view with this component the tags that are in the Tag History expression do not update at the leased rate and continue to only update at their base rate. This seems like a bug, but I wanted to confirm. It does not make a difference if the tags are through an expression or the direct tag entry.
I wouldn’t consider this a bug. You aren’t subscribing to the live tag, you are subscribing to history in the database.
