XY trend

XY trend

I'm converting an V6.21 application in V6.51build0. I have a developer license and ETM is included.
In this application after conversion ETM XY trend is not working.
Even if I try to do a new page with standard zenOn object, and manage in Runtime everything with zenOn functionallity, I'm not able to see trend.
I'm sure data is in archive because if I change from XY to XT I can see trend.
Something new in this version?
Some knew problem?
Thank you
