Sorry for not being able to answer yet, the xyplot object is
really not one of the easiest to understand;-) There are that
many scale factors and cases involved that I haven't yet un-
derstood what's going on in there yet (and there also seem
to luk some bugs someone else has reported). I'm still in
the process of trying to find my way through the whole mess.
So, due to my lack of understanding of what's going on in there
(and perhaps also misunderstanding your question): did you try
to use fl_get_xyplot_xmapping() and fl_get_xyplot_ymapping()
and use just the last argument? As far as I understand it at
the moment, these should be the x and y screen coordinates of
the origin of the axes system.
Best regards, Jens
