I am using Historical SQLTags to trend some PID loops. I have a screen that shows the last 15 minutes of the PID loops activity. Ifa value does not change within that 15 minutes, it does not show that value in the trend. Can we have it so Historical SQLTags will query farther back in the event of no data being found in the charted time? ---

1. 7.1.1 Build 5109 2. Easy Chart 3. Real Time Chart, so no query parameters. ---

Ok, this turned out to be a very subtle/tricky issue, and has been fixed. Problem was localized to seed values- the system wasn’t loading all seed values when those values all came from the same “window”, like a startup. Regards, ---
