The linewidth parameter is not shown [in the documentation](https://matplotlib.org/api/_as_gen/matplotlib.pyplot.figure.html#matplotlib.pyplot.figure). There is no corresponding `set_linewidth` figure method.\r\n\r\nAlso, when saving to a file, this border is missing.\r\n\r\nI am using Jupyter notebook.\r\n\r\n**Code for reproduction**\r\n```python\r\nfig = plt.figure(linewidth=20, edgecolor='r')\r\nplt.plot([5,6])\r\nplt.savefig('/Users/Ted/Desktop/figlw.png')\r\n```\r\n\r\n**Actual outcome (in notebook)**\r\n\r\n\u003cimg width=\"394\" alt=\"screen shot 2017-10-11 at 11 32 37 am\" src=\"https://user-images.githubusercontent.com/7226751/31450707-1b68a7a6-ae78-11e7-83cb-e0d57d28abb2.png\"\u003e\r\n\r\n\r\n**Expected outcome**\r\n\r\n\u003c!--A description of the expected outcome from the code snippet--\u003e\r\n\u003c!--If this used to work in an earlier version of Matplotlib, please note the version it used to work on--\u003e\r\n\r\n**Matplotlib version**\r\n\u003c!--Please specify your platform and versions of the relevant libraries you are using:--\u003e\r\n  * Operating system: OSX\r\n  * Matplotlib version: 2.1\r\n  * Matplotlib backend (`module://ipykernel.pylab.backend_inline`):\r\n  * Python version: 3.6\r\n  * Jupyter version (if applicable): 5.0\r\n  * Other libraries: \r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\r\nUpdated through conda\r\n\u003c!--If you installed from conda, please specify which channel you used if not the default--\u003e\r\n\r\n","author":{"url":"https://github.com/tdpetrou","@type":"Person","name":"tdpetrou"},"datePublished":"2017-10-11T15:37:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/9370/matplotlib/issues/9370"}
