As an epic hack/workaround. Could you set bars of zero height to instead be of height, 10e-5. Or something small compared to whatever the current scale on the y-axis is. Or call ax.set_xlim yourself after plotting? It's not ideal, but does it help? Like Ben said, the bbox should account for all possible bar locations, regardless of height, for this to behave as expected. -- Damon McDougall http://www.damon-is-a-geek.com B2.39 Mathematics Institute University of Warwick Coventry West Midlands CV4 7AL United Kingdom ------------------------------------------------------------------------------ Everyone hates slow websites.
