Problem with trends

[Anonymous user]

Good day.

When i try to build a trend of an analog point (point value changes very slowly, 1 change in 1-2 days) and when i use ruler on my trend the current value shown as unidentified.
how can i fix this problem.

Thanks

You might need to provide a screenshot of this.  It's not ringing any bells for me having seen it before.

If you could also tell us what configuration your trend line has (because I suspect when you send the screenshot it's going to say 'Processed Historic', so you should tell us what algorithm, resample interval etc you have configured).

If it's configured as a 'Raw Historic' and you don't have a sample within the time window being displayed, then I could somewhat understand this (although it would be nice if ViewX would display the closest data point available)..

Usually when I have very little values going into history it is because I need to set the Significant Change on the Analog Point tab. I use Absolute and then whatever value is applicable. Sometimes the value that i need to use creates to many Historic records but it is desired for other things, so then I have to setup Compression on the Historic tab.
