Hello, Using 0.87.4, I'm getting this traceback with a date plot: /usr/local/stow/matplotlib0.87.4/lib/python2.4/sitepackages/matplotlib/dates.py in _from_ordinalf(x, tz) 154 dt = datetime.datetime.fromordinal(ix) 155 remainder = x  ix > 156 hour, remainder = divmod(24*remainder, 1) 157 minute, remainder = divmod(60*remainder, 1) 158 second, remainder = divmod(60*remainder, 1) ValueError: need more than 0 values to unpack > /usr/local/stow/matplotlib0.87.4/lib/python2.4/sitepackages/matplotlib/dates.py(156)_from_ordinalf() 155 remainder = x  ix > 156 hour, remainder = divmod(24*remainder, 1) 157 minute, remainder = divmod(60*remainder, 1) And sure enough, ipdb> divmod(0.0,1) (0.0, 0.0) ipdb> divmod( 24*remainder, 1 ) () It looks like divmod is getting overloaded (?) or something in CXX/cxx_extensions.cxx with [perhaps] this code: Py::Object PythonExtensionBase::number_divmod( const Py::Object & ) { missing_method( number_divmod ); return Py::Nothing(); } which would make sense, but I haven't explored it that thoroughly. I think what's happening is that I've got a numpy array scalar that is sneaking in there somewhere. For now, I'll just use the hackfix of casting remainder to a float. Thanks, Glen
