I use 8 point fonts and tight_layout. In the resulting PDF, the x and y labels are cut.\r\n\r\n\u003c!--A short 1-2 sentences that succinctly describes the bug--\u003e\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug, also minimizing the number of dependencies required--\u003e\r\n\r\n```python\r\nimport matplotlib\r\nmatplotlib.use('agg')\r\nimport matplotlib.pyplot as plt\r\n\r\nmatplotlib.rcParams['font.size'] = 8\r\n# matplotlib.rcParams['text.hinting'] = 'none' # uncomment to fix problem\r\n\r\nplt.figure(figsize=(.5,.5))\r\nplt.xlabel('qyg')\r\nplt.ylabel('ETZ')\r\nplt.yticks([])\r\nplt.xticks([])\r\nplt.gca().spines['right'].set_visible(False)\r\nplt.gca().spines['top'].set_visible(False)\r\nplt.gca().spines['bottom'].set_visible(False)\r\nplt.gca().spines['left'].set_visible(False)\r\nplt.tight_layout(pad=0)\r\nplt.savefig('output.pdf')\r\n```\r\n\r\n**Actual outcome**\r\n\r\n\u003c!--The output produced by the above code, which may be a screenshot, console output, etc.--\u003e\r\n\r\n[bad.pdf](https://github.com/matplotlib/matplotlib/files/2155253/bad.pdf)\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[good.pdf](https://github.com/matplotlib/matplotlib/files/2155254/good.pdf)\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 16.04.2 LTS\r\n  * Matplotlib version: commit 0f05cf47c5f23729bc82bca25de30f39c57658fd\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): agg\r\n  * Python version: 3.5.2\r\n  * Jupyter version (if applicable):\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\n\u003c!--If you installed from conda, please specify which channel you used if not the default--\u003e\r\n\r\nThe font used is the default matplotlib font:\r\n```\r\n$ md5sum DejaVuSans.ttf\r\n49c0f03ec2fa354df7002bcb6331e106  DejaVuSans.ttf\r\n```\r\n\r\nI believe that the problem is here:\r\nhttps://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/backends/backend_agg.py#L232\r\nhttps://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/backends/backend_pdf.py#L2144\r\n\r\nAs you can see the PDF backend always uses LOAD_NO_HINTING while the Agg backend uses whatever the user specifies. The only workaround that I've found is enabling the commented out line in the testcase above.","author":{"url":"https://github.com/prekageo","@type":"Person","name":"prekageo"},"datePublished":"2018-07-02T13:02:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/11551/matplotlib/issues/11551"}
