Trying to access an object variable by reference but its not working the way I want (the list value will not follow the value of the ping\_stat.min/max/mean). Is it possible to achieve what I want?

Think I solved it. Needed to define local function calls returning the values I wanted.

On the first screenshot you append the current value.  
If you use the function you get the value at the time when you call the function

Im used to be able to access by pointer/reference to object/value but I think this is not the way its done in python. As long as there is a compact way to do it, like a function call (“pointer”) its fine by me.
