[astron97]

According to the docs, the first argument to the callback holds created chart object. How do we access this object?

Hi @astron97 ,

First of all, I want to really apologize for not giving the answer here for these time. I've just checked the callback property usage. Unfortunately it's broken for some reason, and requires to be fixed.
Also, we'll do all the best to resolve the problem as soon as it is possible.

Kind regards!
