I am trying to build a composite plot, with multiple categories, using
In principle, it could be done using facetting, but I do not seem to be able
to get past the defaults, so I try building each plot separately, then
putting them all together using frameGrob and placeGrob.

rather than using the vertical orientation only;
2) draw the numbers on top of the bars (the issue is locating the bars, of
3) extract the definition of the axes (scales, with breaks and labels) from
the individual plots

I would appreciate any pointers.
