Thanks Peter,
But I could not make sense of the reply, sorry.
As shown in the above images – the Y Axis is NOT automatically scaled.
I followed the documentation, and everything I could find on the internet, and could not make it work.
Here is a jsfiddle, based on one of the examples from your documentation, where you can see that it is not auto scaled, not by default, and not manually.
This chart is not displayed properly.
