Historical data shown in a Perspective table

I’m looking at at the history of a tag in Perspective table. It seems the table only show the data captures when the tag change in the period I’m looking.

See this picture. I’m asking to see the data from (May 9, 1:11 PM) to (May 12, 1:11 PM). It’s only showing the timestamp when the data change. I’d like to have the values at the beggining and the end of the date range.

How can I do that?

Hi @vrautomation, I believe tag collection is based ‘on change’ by default. Can you confirm whether this is the case for you, or whether you are using the ‘periodic’ logging?

It is “on change”. My point is I would also like to see the value of the point at the beggining of the time range.
