This new FancyArrow stuff looks great, but I'm having trouble getting it to
work. All of the gallery examples I see seem to only use it thru an
'annotate' call. I just want to draw these arrows directly.
I tried the following, but it just draws a plain line:
ax = gca()
c = matplotlib.patches.FancyArrowPatch((0.2, 0.2), (0.5, 0.5),
arrowstyle="->")
ax.add_patch(c)
I also tried uisng __call__ on an ArrowStyle instance:
a = matplotlib.patches.ArrowStyle.Fancy(head_length=.4, head_width=.4,
tail_width=.4)
pth = matplotlib.path.Path( [[.3,.1],[.7,.5]] )
a(pth,1,1)
This gives an error. (it looks like it tries to access path.codes[:], which
from what I can tell shouldn't be accessed directly - so maybe this is a
bug?).
Any hints on how to draw FancyArrow?
thanks,
Ken
