Trend does not show the correct property value

Hi All, 

I created a trend showing the OperatingMode property, butthe graph is not showing the correct values when I change the time range selection.

 

OperatingMode property values are the following (QueryPropertyNamedHistory service output):

The graph is correct when I select the time range

From 2019-07-31 07:00:00 -> To 2019-07-31 10:39:00

While the graph is not correct when I select the time range

From 2019-07-30 07:00:00 -> To 2019-07-31 10:39:00

The property value is not equal to 1 in the selected time range

Any idea? Many Thanks Martina

Hi All, I found that there is a JRA ticket saying:

  • MFG Trend functions which use Dygraph Widget, display average Y-axis value when X-axis time frame is over 1 hour to gain a better performance
  • An original-value-display improvement will be discussed in the furture after release of MFG 8.4.0

I have the 8.4.2 release installed, and the average is still displayed.

 

Thanks Martina
