Trend indicators
Hi, I'm having a real variable drawn on trend. Depending on some other variables (bool, or int) thickness and color of the pen dinamically changes. Is it possible, instead, to draw a vertical line in that moment in time that the (bool, or int) variable changes and write a string next to that line containing the value of bool or int? It's like writting parameters of the current trend every time parameters change. And archieve it like that.

I don’t think that is possible. I think that the entire line has to be the same color or thickness. There is no way to change just a portion of the line.

Hello,
Can you describe usecase or add more info, In Freelance - Digivis, thickness and color of the pen can not be changed dinamically. it can be changed online from parameter setting. No idea about trend in System 800xA,
sounds strange requirements!
if pr::<app name>:Application:<var name> then Pen(Yellow, 1) else Pen(Brown, 1)
This changes color of pen depending on <var>. But this doesn't store information when <var> changed, so when it does change, entire trend is coloured in the manner of the current criteria match. Meaning the information is lost. It's just for presentation for the operator. We are aiming for some future diagnostics, where we can look at trend history and immediately see, on trend, which conditions were active during which period of time.
