Re: [Matplotlib-users] FancyBBox set_width

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

I had to deal with this lately, and there is no current way to do what you
want without patching the MPL source.  I have a patch for it, but it does
not behave well enough to use in the general sense....and you have target
the correct code, the lack of flexibility lies in the Text._draw_bbox
function.

I'm afraid that you will have to create the FancyBboxPatch (the arrow)
directly, size it and place it, and then create some text (with no box) to
go inside.
