You can set the x-axis painter and linkpainter to none. And adjust the
y painters to keep only what you want. The only think I'm not yet sure
about is how to deal with the percent values. Write the values at the
bars is easy by the graph text style, but make them to align at the
same position. Well: stack an invisible bar would be a solution.

Yes, the graph data facilities are quite limited with respect to
performing those operations. (Basically all you can do is to do some
math on the columns.) I'm sorry for that, but you can always build you
own data and pass it to graph.data.list(). However, at some point we
should add some useful features to the PyX data containers.

We had a discussion about this just a few months ago:
http://sourceforge.net/mailarchive/message.php?msg_id=14963640

Maybe you're also interested in my reply. Overall this solution is
fine but we should add an appropriate style to the PyX core. I'll take
it onto my todo list.

HTH,


André
