I've never used plotfile before, but it seems like a simple quick'n'dirty
function, good for having a quick glance at how the data look like. Which is
also what the documentation for plotfile says.
So in this case, your points 1 and 2 can be solved using the more generic
approach, reading the file separately (possibly using a csv module) and using
pylab.bar to plot your data. pylab.bar has a 'width' option, which would easily
solve problem #2.
I can also advice you to try the matplotlib mailing list: people will there
will be much more knowledgeable wrt to matplotlib and pylab than on this
mailing list:

Good luck,
Evert
