Hi Friends,

One of our client still have his 7.2.11 ignition running and we have some doubts a about trends. In particular, with “real time mode”, when the tag changed before the initial time of the trends, the value shows a zero, but actually, the value is in one.  
Maybe with this picture you can understand better:

the blue line of the first subplot is an example of this behavior.

This are some tips for this trends:

- All pen were historized with discrete mode
- The aggregation mode is min/max (but with avg happens too).
- the pen is drawed as digital.

Any clues or an explanation of this?

Thanks in advance.
