Jordan, Are you sure you want to use a LineCollection for this? If you do, someone is sure to say, "But I want red arrows with black borders..."
My impression from the earlier posts on this topic was that part of the trouble was an attempt to be too clever and too automatic; this was interfering with getting the transforms right so that the arrows would look right, like text, regardless of how the axes are stretched or squished. Maybe the LineCollection makes this easier, but I am reasonably sure it can be done cleanly and well with PolyCollections also. (I am biased toward the PolyCollection approach because it is closer to the m_vec.m functionality I added to Rich Pawlowicz's m_map; I will need something like this for basemap if it does not already exist.)
