So our sales guy* is creating a demo system that runs in a VM on his laptop. Because he doesn’t want/need huge volumes of data he has configured the history to use 5 minute partitions and purge anything older then 15 minutes.
When he went to the trend page it showed data in the future . What it looks like is happening is the last valid point is being duplicated as the last point on the graph so you end up with a flat line from the last good point to the right edge of the graph.
*A new tag line: Ignition, control software so easy, sales can use it!
