This is of interest to me, and it's nice to know that this is do-able with matplotlib, but like many of the examples, I find it sorely lacking in documentation. For example, why are the points and segments arrays shaped so specifically the way they are? Why the call to set_array? Could the same thing be accomplished with a call to set_facecolor? I hope the same things can be accomplished in a more straightforward way. Any illumination on these points would be appreciated.
