[Matplotlib-users] FancyArrows don't connect

[Thomas R. <tho...@gm...>]

Hello,

I'm trying to plot two perpendicular arrows and getting them to start  
from the exact same point. If I try the following:

---

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as mpl
from matplotlib.patches import FancyArrowPatch

fig = mpl.figure()
ax = fig.add_subplot(111)

arrow1 = FancyArrowPatch(posA=(0.5, 0.5), posB=(0.6, 0.5), \
                 arrowstyle='-|>', mutation_scale=20.)

arrow2 = FancyArrowPatch(posA=(0.5, 0.5), posB=(0.5, 0.6), \
                 arrowstyle='-|>', mutation_scale=20.)

ax.add_patch(arrow1)
ax.add_patch(arrow2)

fig.savefig('fancyarrow.png')

---

then the result are two perpendicular arrows but the arrows don't  
touch at their origin (see attached image). Is there a way to fix this?

Cheers,

Tom
