Oh I see. So I had a look at the examples and I think you could try using the compute extremes option (again, see attached example). This is relatively neat. Please note that you need to change the colour at three places when you do this (because it essentially fills from the avaerage to the top, from the average to the bottom, after which the line itself is still visible so I had to make that one by the same colour).
