There was some private discussion between Jörg and myself about this issue. Also the open bug report and all that. We came to the same conclusion, that we want to have layers in the graph. Please stay tuned. We can probably remove all the do-method magic by that (at least hide it completely from the user). At the moment you can do a g.dodata() to force the data being printed before (i.e. below) the axes.
