Hi Kimmo, Unfortunately, I can't visualize the attachment. Could you provide an example I can reproduce?

Unfortunately your suggestion is not working. Please have a look on the attachment, I have added manually the mean lines I am trying to plot. The problem with 'abilne' seems to be that the argument 'v' is relative to the graph area, not the x-axis scale. Thus, plottingat v='mean' won't work... Any suggestions?
