Setting minimum / maximum causes other issues
like here : https://jsfiddle.net/QwZuf/2685/
If you click on the legend then the YAxis will not hide and will show some random set of numbers.
If you remove the minimum property and try again, then the yaxis will hide
This does not look like a problem in this case but if I have another series
https://jsfiddle.net/QwZuf/2686/
then on hiding one series does not hide its corresponding axis and it is not visible to which axis a series is on.
Apart from this if the x-axis is of time date-time and if the y-axis has minimum/maximum set then hiding series causes console errors and sometimes the page stops working due to those breakages.
So that is why I want to avoid setting minimum / maximum on the axis
