Below are 2 easy chart screenshots, all default settings, I just dragged the tags from the tag browser onto the chart.
In the third screenshot, you'll see that I can pull up several days worth of data as long as the data is from before Feb 12th, where the data turns into a straight line (which goes away when I turn off "Allow Tag History Interpolation").
Has anyone dealt with this before?
This normally means there is simply no history since the start of the straight line, did you change deadband or tag history settings?
I have not made any changes.
There is tag history data, I can see it when I reduce the time interval (or zoom in). It just thinks there isn't any when trying to display data after the 12th. I thought maybe the queries were timing out or something but for older data I can query for a week's worth of data with no issues.
