(PyPlot has one, but the mismatch in axes requires that I do some unusual transforms to my gradient matrices for them to display properly.)
Just checking in to say I agree this would be extremely useful. Obviously the framework in Annotations is basically there to do this. Presumably the hard work is in deciding how to subsample the voxel data? I'd guess that having 10^6 arrows isn't all that useful?
Yeah, I really was putting this here as a note. I'll probably get to it at some point, though I wouldn't mind at all if someone else implemented if first. :-)
The quiver function in matlab/matplotlib draws arrows according to a given
(dx, dy)
gradient field.
