Bi-linear interpolation in PI AF tables

Dear community members,


I am looking into ways of creating a bi-linear interpolation to lookup a result in a AF table. I have found an old post from 2013 indicating that this was not possible directly (needed lengthy roundabout way).

I was wondering if some development/smart ideas had come up on that topic since. Just to clarify below is a description of what I am attempting:


* table is structured with 3 columns (X,Y,R)

* I have a realtime value for X and Y and would like to get the corresponding R. Of course the Xs and Ys in the table do not match the realtime values.


Thank you for your time,
