tailwidth?

How can I change linewidth of this arrow?
arrow1=pylab.annotate("", xytext=(-3500,-1e8),
xy=(-3500,8e8),fontsize=8,arrowprops=dict(arrowstyle="<->"))
Thank you in advance.

I know this is an old post, but just in case.

For arrowstyle="<->", they are just lines (well, not exactly as a
matter of fact). So, what you need is to change their linewidths. You
may do

arrow1=pylab.annotate("", xytext=(0.1,0.1),
xy=(0.9,0.9),fontsize=8,

arrowprops=dict(arrowstyle="<->,head_length=1,head_width=0.8", # I'm
changing the head_length and head_width to make the arrow more
visible.
linewidth=3))

On the other hand, the underlying artist associated with the arrow can
be accessed by *arrow1.arrow_patch*.
Note that it is actually an instance of Patch.
