Thanks for pointing out this drawing arrow patch.
I wrote a quick function to use this.
Figuring out the correct width to use requires some experimentation.
It would be nice if we could eventually have a line with a regular
line width, and a nicely sized arrow head. (Any ideas?).
But this gives nices results.

from pylab import *
def draw_arrow( x, y, dx, dy, width=1, color = 'k' ):
ax = gca()
a = Arrow( x, y, dx, dy, width )
a.set_edgecolor(color)
a.set_facecolor(color)
ax.add_patch( a )
draw_if_interactive()
return a
How did you find out how to use a patch? Trial and Error?
I couldn't find any documentation other than http://matplotlib.sourceforge.net/matplotlib.patches.html
and that doesn't show how to use it.
