Feature: clamp y-axis min and max

[abursavich]

What would you like to be added:

I would like an option to clamp the max and/or min y-axis value without specifying a fixed min or max value, which would allow the max and min to be automatically adjusted within that range (of the min-min and max-max).

Call it whatever you want: clamp max, max max, soft max, hard max, something completely different...

It can be a different field or a checkbox next to each current min and max.

Why is this needed:

Frequently, especially when dealing with percentages, I don't want to set the min and max (e.g. 0% and 100%), because I want the y-axis to be zoomed in when the elements are all clustered together (e.g. between 20% and 30%). However, I don't want the y-axis to extend beyond the valid values (e.g. 0% and 100%) when the elements are not clustered together (e.g. between 5% and 95%).
