If I use `fig.legend()` method to produce legend and use `bbox_inches='tight'` in `savefig()` method. The legend is not present in the produced image (using the argument `bbox_extra_artists` also does not work). If I use `ax.legend()` instead, the legend is present in the saved image.\r\n\r\n**Code for reproduction**\r\n```python\r\nimport matplotlib.pyplot as plt\r\nimport numpy as np\r\nimport matplotlib as mpl\r\n\r\nx = np.arange(-5, 5, 0.1)\r\ny1 = np.sin(x)\r\ny2 = np.cos(x)\r\n\r\ny3 = np.sin(2*x)\r\ny4 = np.cos(2*x)\r\n\r\nfig, (ax1, ax2) = plt.subplots(ncols=1, nrows=2, figsize=(10, 6))\r\n\r\nax1.plot(x, y1, label='sin')\r\nax1.plot(x, y2, label='cos')\r\n\r\nax2.plot(x, y3, label='sin')\r\nax2.plot(x, y4, label='cos')\r\n\r\nhandles, labels = ax1.get_legend_handles_labels()\r\n# following code does not work\r\nlegend = fig.legend(handles, labels, loc='lower left', ncol=2, frameon=False,\r\n              bbox_to_anchor=(0.12, 0.88))\r\nplt.savefig('test.jpg', bbox_extra_artists=[legend,], bbox_inches='tight')\r\n\r\n# following code works\r\n# legend = ax1.legend(handles, labels, ncol=2, frameon=False,\r\n#                     loc='lower left', bbox_to_anchor=(-0.01, 1.2))\r\n# plt.savefig('test.jpg', bbox_inches='tight')\r\nplt.show()\r\n```\r\n## outcome\r\nThe saved images are different if I use different legend method.\r\n### using `fig.legend` method\r\n![image](https://user-images.githubusercontent.com/16662357/34658251-8e382b0e-f468-11e7-912b-2b2eba51598f.png)\r\n\r\n### using `ax.legend` method\r\n![image](https://user-images.githubusercontent.com/16662357/34658289-c5cb6d24-f468-11e7-93d2-b5c149c51095.png)\r\n\r\n\r\n**Matplotlib version**\r\n  * Operating system: Windows 8.1 and Linux (CentOS 7) (This problem is maybe platform independent)\r\n  * Matplotlib version:  2.0.2(Linux), 2.0.0 (Windows)\r\n  * Matplotlib backend: Qt5Agg\r\n  * Python version: 3.5.2 (Windows), 3.6.2 (Linux)\r\n\r\nThe matplotlib and python are all distributed with Anaconda.\r\n\r\n\r\n## quesiton\r\nIs this a bug or something I do not know. Maybe there is difference between `fig.legend` and `ax.legend` method?","author":{"url":"https://github.com/jdhao","@type":"Person","name":"jdhao"},"datePublished":"2018-01-08T03:49:49.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":16},"url":"https://github.com/10194/matplotlib/issues/10194"}
