2 years ago IF anyone else runs into this, it can be fixed by wrapping both the x and y data in the set_data statements with np.array. Change these two lines to the following:
currently on line 80 in def init(): line.set_data(np.array([]), np.array([]))
currently on line 98 in def animate(i): line.set_data(np.array([start[0], end[0]]), np.array([start[1], end[1]]))
After that the demo should work.
Thanks,

Good day and thanks for your work. I'm trying to run the demo2.py to get the rotating 3d image, and the image window does appear with the axes, but no drawing of the rotating figure. I'm getting a traceback:

I found one post on stackoverflow that says to use numpy.array, but you're doing that already. Thank you again....... Tom C.
