Re: [Matplotlib-users] FancyBBox set_width

[Daniel H. <dh...@gm...>]

Another, very hacky but quick way to do this, is to put spaces around your
text until the arrow is the size you desire:

"         your text           "

and if you want the arrow to expand upward and downward, put in return
characters (I told you it was crude ;))
