Re: [Matplotlib-users] Arrow with a dashed line
Just to clarify, both arrowstyle='simple' and arrowstyle='-|>' draw arrows as patches. In your first example with arrowstyle='simple', the arrow is drawn as filled patch without edges, i.e., linestyle is not effective. arrowstyle="-|>" also uses a patch but no "fill", only "stroke".

Nevermind: I though arrowstyle='simple' and arrowstyle='-|>' were the same
thing, but apparently not (I guess one draws the line as a patch, and the
other as a line). So the following works as expected:
#
import matplotlib.pyplot as plt
fix, ax = plt.subplots()
ax.set_xlim((-1,5))
ax.set_ylim((-5,3))
ax.annotate('simple', xy=(2., -1), xycoords='data',
xytext=(100, 60), textcoords='offset points',
size=20,
arrowprops=dict(arrowstyle="-|>",
fc="k", ec="k", linestyle='dashed',
connectionstyle="arc3,rad=0.3"),
)
plt.show()
#~~~

[Matplotlib-users] Arrow with a dashed line
Is it possible to draw an arrow with a dashed line?
I tried using a fancy arrow patch and set the linestyle:
#~~~
import matplotlib.pyplot as plt
fix, ax = plt.subplots()
ax.set_xlim((-1,5))
ax.set_ylim((-5,3))
ax.annotate('simple', xy=(2., -1), xycoords='data',
xytext=(100, 60), textcoords='offset points',
size=20,
arrowprops=dict(arrowstyle="simple",
fc="0.6", ec="none", linestyle='dashed',
connectionstyle="arc3,rad=0.3"),
)
plt.show()
#~~~
But the linestyle argument just gets ignored.
Is there a way to grab the connection path object and then change that to a
dashed line? Actually, I'm not even sure it's possible to set a linestyle
for a Path (since dashed lines are normally Line2D). Suggestions?
Thanks,
-Tony
