[Matplotlib-users] FancyBBox set_width

[Peter C. <pco...@gm...>]

Hi all,
I'm trying to have a Text object with a fancy box, as in this example:
http://matplotlib.sourceforge.net/mpl_examples/pylab_examples/fancybox_demo2.py.
 However, the key difference is that I want to have the box (in my
case,
I'm interested in an RArrow) be a specified width (in units of the plot),
rather than just fitting it to the text I've given (crude ascii art
below).  The following seems not to work:


ax = gca()
txtobj = ax.text(0, -.1 * yrange, 'text',
                     bbox=dict(boxstyle='rarrow'))
txtobj.get_bbox_patch().set_
width(SIZE_IM_INTERESTED_IN)
draw_if_interactive()

It seems like draw()ing the text object will reset the size of the BBox...
Any idea how to fix this? At the moment, I'm experimenting with continually
drawing, polling the get_width() method, and when it's too small, adding in
spaces around the text field, but that seems both not to work reliably, and
be an incredibly boneheaded way to go about it.

I'm using matplotlib v. 1.1.0 if that makes a difference.
