[matplotlib-devel] all 3d examples broken on branch

[John H. <jd...@gm...>]

This appears to have escaped my tests :-(

All of the 3d examples are failing on the 1.0.1 branch -- can anyone
replicate this?

AttributeError: 'Axes3DSubplot' object has no attribute 'xaxis'


I tried the naive fix in lines.py

    def set_axes(self, ax):
        Artist.set_axes(self, ax)
        if getattr(ax, 'xaxis', None):
            self._xcid = ax.xaxis.callbacks.connect('units',
self.recache_always)
        if getattr(ax, 'yaxis', None) is not None:
            self._ycid = ax.yaxis.callbacks.connect('units',
self.recache_always)
    set_axes.__doc__ = Artist.set_axes.__doc__


but this just pushed the bug downstream

Perhaps someone with more understanding of 3D internals can correct this?
