Hi there
I'd like to create a trendline in a graph like we usually do in plans with exponential trendlines, parabolic and linear.
Is there any way to do this through PI or I should create an equation that does that?
Thanks!

Hello Lal Babu Shaik,
Thank you for your answer
I'm sorry but I never used AF Analysis Equation and I really don't know where I find it. In Af analysis equation is there any trendline suggestion?
Thanks,
Carlos
Carlos, in your question, you mentioned exponential trendlines, parabolic and linear. To men, that sounds like what could be referred to as a fixed-reference curve, or fixed data set.
Since the PI system is a time based system, all data points must have a time reference. A fixed data set, by definition, generally DOESN'T have a time reference.. but you require it to have one.
A few years back, I wrote an article explaining how to accomplish this, a link follows.
Hi Carlos
AF Analysis equation or AF table with values with PI Vision XY plot should give output you are expecting.
Thanks,
Lal Babu
