Just a guess.\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: Ubuntu 16.04\r\n  * Matplotlib version: 3.0.0\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): inline\r\n  * Python version: 3.5.2\r\n  * Jupyter version (if applicable): Jupyter Lab 0.33.6\r\n\r\n\u003c!--Please tell us how you installed matplotlib and python e.g., from source, pip, conda--\u003e\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/Phlya","@type":"Person","name":"Phlya"},"datePublished":"2018-10-12T14:53:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/12505/matplotlib/issues/12505"}
