        "\n# Placing text boxes\n\nWhen decorating Axes with text boxes, two useful tricks are to place the text\nin axes coordinates (see `transforms_tutorial`),\nso the text doesn't move around with changes in x or y limits.  You\ncan also use the ``bbox`` property of text to surround the text with a\n`~matplotlib.patches.Patch` instance -- the ``bbox`` keyword argument takes a\ndictionary with keys that are Patch properties.\n"
