Like the title says, I’m trying to get a sparkline in a Perspective view. The line is showing in the designer but not in a session (Chrome or Firefox). I tried closing the view, reopening it, closing the designer, and other things to try to make the spark disappear in the designer, but it remains. I also tried to refresh my session, clear cache, reboot the server, and I couldn’t get the spark to show up. What I do know is that if I disable the Tag History binding and keep the 50 points in the dataset, I’ll get a line in the designer AND in the session.
I have a Tag History binding type defined on the
points dataset of the sparkline.
As you can see, what is different (v8.1.14) is that I’m using an expression for the tag definition. Here is the key that’s displayed in the snip:
I set up this structure according to the docs here.
Any ideas why this is happening?
