I'm sorry, this is a bug. (It has its origin in the way we did bar
graphs in older releases, where a bar needed to make the nesting and
the stacking all at the same time.) Fixed it in changeset 2576.
However, without nesting of bar axes and styles, you don't need to use
changeable attributes and than the problem doesn't occur. And when
using the bar style multiple times the proper select is performed at
PyX 0.8.1 as well, such that with the following changes everything
should work as expected.
