Here is my example code\n\n```\nimport matplotlib.pyplot as plt\n\nfig = plt.figure()\nax = fig.add_axes([0.2, 0.2, 0.6, 0.6])\narrow1 = ax.annotate('text', xy = [0.5,-0.2], xycoords = 'axes fraction', \\\n    xytext = [-72,0], textcoords = 'offset points', \\\n    arrowprops = dict(arrowstyle = '-|\u003e', mutation_scale = 10.0, \\\n    shrinkA = 0, shrinkB = 0, linewidth = 1))\narrow2 = ax.annotate('', xy = [0.5,1.2], xycoords = 'axes fraction', \\\n    xytext = [-72,0], textcoords = 'offset points', \\\n    arrowprops = dict(arrowstyle = '-|\u003e', mutation_scale = 10.0, \\\n    shrinkA = 0, shrinkB = 0, linewidth = 1))\nfig.savefig('test.png')\nfig.savefig('test-tight.png', bbox_inches = 'tight')\n```\n\nHere is test.png, showing that I have two annotations. One annotation, with text, below the axes and one annotation, without text, above the axes.\n\n![](http://i.stack.imgur.com/5DaZl.png)\n\nHere is test-tight.png, showing only one annotation. The annotation above the axes, without the text, has been ignored.\n\n![](http://i.stack.imgur.com/dAR8h.png)\n\nLooking in the source code, `bbox_inches='tight'` attempts to find the size and location of artists by calling `artist.get_window_extent()`. When I try `arrow1.get_window_extent()`, I get a bounding box that appears to correspond to the text. When I try `arrow2.get_window_extent()`, I get a bounding box with zero height and zero width. Thus, the root of the problem is `.get_window_extent()` doesn't include the arrow.\n\nAny ideas for how to get around this, in a reasonably robust manner? If I could somehow get the proper bounding box for the whole annotation, then I would be in business. However, I can't even seem to get the line or patch objects out of arrow2.\n\nIn case it matters, I am on matplotlib 1.4.0, Python 2.7.6, and Mac OS X 10.8.5\n","author":{"url":"https://github.com/breedlun","@type":"Person","name":"breedlun"},"datePublished":"2014-11-19T14:04:22.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/3816/matplotlib/issues/3816"}
