How to turn a 3D chart into something watchable on a 3D television?

You could generate two images (for the left and right eyes) for each frame of your animation, set them up side-by-side (to make a very wide image, or a horizontally squashed one), and generate a video file that way. Then put that file onto a USB drive and plug it into a modern 3D TV, and look in its 3D menu, you should find a "side-by-side" or "SBS" option which will understand how to display the image. (Search YouTube for "GoPro 3D" for many examples.)

You might be able to do the same with a computer connected to the TV as a monitor, but the non-3D parts of the desktop would need to be hidden since they wouldn't be duplicated for each eye (and would look odd).

Note: If you do connect a computer to a 3D screen in SBS mode, you'll find it useful to close one eye at a time while navigating to start your presentation.
