[yt-users] draw_domain failure

[Chang-Goo Kim]

Hi Sam,

It works! I think you'd better to change documentation for this too. I
found previous syntax from following link:

http://yt-project.org/docs/dev-3.0/reference/api/generated/yt.visualization.volume_rendering.camera.Camera.draw_domain.html#yt.visualization.volume_rendering.camera.Camera.draw_domain

Thanks a lot!
