There should be a field button for inverting the axis. For example, instead of the Y-axis moving upwards from 0 to 100 it should be able to flip and start at 100 and move upwards to 0.
This type of chart is very useful when dealing with ranking movement where no.1 is at the top.
This is the same as idea 'Reversible x axis'

Agreed. My "for example" would involve the X-Axis, but this request seems to be for both.
