Re: [Matplotlib-users] 'Poly3DCollection' object has no attribute '_facecolors2d'

[Benjamin R. <ben...@ou...>]

Yup, that is a real bug... self._facecolors2d doesn't get set until the
first draw. It really shouldn't be accessing _facecolors2d because the
elements can change order depending on the rotation of the display. Could
you file the bug report, please?

Thanks!
