matplotlib-devel Mailing List for matplotlib

Pierre,
I don't think John follows the numpy list closely, so I am forwarding this.

FancyArrow was written by a colleague of Fernando -- perhaps you an
provide a free-standing script that illustrates the problem and
Fernando can pass it on to the original author to take a look.

Hello list -
I tried this on the user's list, but didn't get a response.
I am afraid it is a bug.
I am trying to use FancyArrow to draw an arrow with given length.
The length I use is from 0 to 100.
I specify length_includes_head=True.
This works fine when I specify a width and length.
But when I specify an overhang, the length of the arrow becomes much longer
than 100.
Am I using overhang incorrectly?
Here's a script with the problem:
from pylab import *
from matplotlib.patches import FancyArrow
axis([0,120,0,100])
ax = gca()
a = FancyArrow( 0, 40, 100, 0, length_includes_head=True, head_width=5,
head_length=5)
ax.add_patch(a)
b = FancyArrow( 0, 60, 100, 0, length_includes_head=True, head_width=5,
head_length=5, overhang=5)
ax.add_patch(b)
draw_if_interactive()
Thanks, Mark
