Feature Request: queries in Y-Max / Y-Min

[minfrin]

What would you like to be added:

You have a panel containing disks on a server, and how full they are. You want to graph the disk used out of the total disk. Both "disk used" and "total disk" come from queries. The Y-Min and Y-Max in this case come from the query.

Most specifically, I want query A to be the value, query B to the Y-Min, and query C to be Y-Max.

This is a different approach to #3935.

Why is this needed:

Right now it is impossible to graph disk space, or anything else represented as a fraction.

You end up with this meaningless graph:

All widths are calculated as a percentage of the biggest width, which is arbitrary and has no relation to the others.

To summarise, right now this graph is impossible to render in grafana:
