Is there a way I can do plots for variables that are confined to a simplex? For example, I often work with variables that are frequencies, so, say, x + y + z = 1. I can obviously do an ordinary 3D plot, but since the action is confined to the simplex x+y+z=1, this is a bit silly. I can obviously use primitives to hack a picture, but that won't help me the next time I need to look at a different system that's subject to the same constraint. In some fields simplices like this are called triangle plots, though they can obviously have dimensions > 3. Any suggestions are welcome! Cheers, Gordon
