The +n0c/20p was supposed to lift the label up from the corresponding line. I changed it to +n0c/2c to keep the units consistent. No help. 

Might there be a conflict with the +v (follow path) option? Removing +v leads to an offset, however the offset is not "considered in the coordinate system defined by the orientation of the line" (quote from man psxy > +ndx[/dy]). It applies the offset always oriented on the page, not by the line. Maybe I'm interpreting the man page wrong, but I expect the label offset orienting itself on the line and the direction of the line.

All the best, Kristof
