It only works properly if `plt.show()` is called inside the block.\r\n\r\n**Code for reproduction**\r\n\r\nThis reproduces the bug:\r\n```python\r\nimport matplotlib.pyplot as plt\r\n\r\nwith plt.style.context('seaborn'):\r\n    plt.axhline(0, color='C0')\r\n    plt.axhline(1, color='C1')\r\n    plt.axhline(2, color='C2')\r\nplt.show()\r\n```\r\n\r\nThis works fine and is the expected behavior:\r\n```python\r\nimport matplotlib.pyplot as plt\r\n\r\nwith plt.style.context('seaborn'):\r\n    plt.axhline(0, color='C0')\r\n    plt.axhline(1, color='C1')\r\n    plt.axhline(2, color='C2')\r\n    plt.show()\r\n```\r\n\r\n**Actual outcome**\r\n\r\n![does_not_work](https://user-images.githubusercontent.com/11193181/40962539-1654efc0-68a6-11e8-9d24-f3b4a455ccc3.png)\r\n\r\nPlease note that other elements of the style are working fine, such as the grid.\r\n\r\n**Expected outcome**\r\n\r\n![works](https://user-images.githubusercontent.com/11193181/40962605-4774e2fe-68a6-11e8-843e-3fb362a50841.png)\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: Solus Linux\r\n  * Matplotlib version: 2.2.2\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): TkAgg\r\n  * Python version: 3.6.5\r\n\r\nUsing matplotlib packaged by the linux distribution.\r\n","author":{"url":"https://github.com/rjurga","@type":"Person","name":"rjurga"},"datePublished":"2018-06-05T07:57:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/11376/matplotlib/issues/11376"}
