What I mean by this is is there some way to have the values display the average, max, min etc. relative to what you set the time scale in Coresight.
Yes. Instead of using datasets in Processbook, you can create an AF attribute with the PI Point Data Reference and make use of the value retrieval methods. In the By Time: field, be sure to specify "Time Range". Do not use "Time Range Override".
When scrolling through time, this adjusts the time context of PI Vision so the value changes. This is expected behavior. To reset it to the current time, you can hit the Now button.
This brings up a good more general point. For those who are mixing PI ProcessBook and PI Vision, the best practice is to use AF calculations rather than PI calculations. In general using AF in ProcessBook makes the display easier to transfer to PI Vision.
How do you create an AF attribute?
What is that screen shot referencing? where did you get that pop up window ?
