I am expecting both magics to produces similar behaviour. I've seen this issue over the last few months in bigger Notebooks and I figured I had other problems but now I've narrowed it down to just the simple case outlined below.\n\nThe problem:\n\n`%matplotlib inline` in a Notebook causes plots to be shown as static images, only 1 call to `%matplotlib inline` is required.\n\n`%matplotlib notebook` in a Notebook enables some interactive features. I have to call this before _every_ plot otherwise I get a non-rendered object in return.\n\nHere I only use `%matplotlib notebook`. The second plot is not rendered. For the third plot I force another call to `%matplotlib notebook` and the third image is rendered.\n\n![mpl_notebook_bug_onlynotebook](https://cloud.githubusercontent.com/assets/273210/9131934/cf6d0e0e-3ce7-11e5-94ad-2bae331eb01a.png)\n\nHere I first use `%matplotlib inline` and then `%matplotlib notebook`. The final plot (second for `notebook`) doesn't render: \n\n![mpl_notebook_bug](https://cloud.githubusercontent.com/assets/273210/9131857/4244a3f2-3ce7-11e5-881f-642c399dedb3.png)\n\nI'm using:\n- Linux Mint 17.2 (Ubuntu 14.04) 64bit\n- Python 3.4.3 (Anaconda 64 bit)\n- IPython 3.2 and Notebook  3.2.0-8b0eef4\n- matplotlib 1.4.3\n\nMaybe I'm being foolish and the point of `%matplotlib notebook` is to only allow 1 plot to be interactive, so you have to choose which one? And then after switch back to `%matplotlib inline`?\n\nAny thoughts to clear up my muddled mind would be gladly received. i.\n","author":{"url":"https://github.com/ianozsvald","@type":"Person","name":"ianozsvald"},"datePublished":"2015-08-07T08:48:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":14},"url":"https://github.com/4879/matplotlib/issues/4879"}
