Thanks for the implementation. It takes only a little tweak to make
the plot useful. What I need to pay attention when tweaking are the
tick- related stuff. The other thing is that I have to suppress the x-
title/title and use xyouts to get a centered x-title/title. Although I
don't need to break up y-axis, I would imagine a hard time to xyouts y-
title in a usual orientation.
