[This page](https://matplotlib.org/gallery/ticks_and_spines/centered_ticklabels.html) explains a method (the one-liner on the top of the page), which does not work.\r\n\r\n**Code for reproduction**\r\n\r\n\u003c!--A minimum code snippet required to reproduce the bug.\r\nPlease make sure to minimize the number of dependencies required, and provide\r\nany necessary plotted data.\r\nAvoid using threads, as Matplotlib is (explicitly) not thread-safe.--\u003e\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nimport numpy as np\r\nimport matplotlib as mpl\r\nprint(\"Matplitlib version: %s\" % mpl.__version__)\r\n \r\nx = np.logspace(-2,3)\r\ny = 1 / (exp(1/x) - 1)\r\n\r\nfig = plt.figure(1, figsize=(4, 4))\r\nplt.loglog(x,y)\r\nplt.xlabel('x')\r\nplt.ylabel('y')\r\nplt.tight_layout()\r\n\r\nax = plt.gca()\r\nax.yaxis.set_tick_params(horizontalalignment='left')\r\n```\r\nThe code above is slightly longer than minimum, to motivate why I need to change the tick label alignment. The changing size of the exponent looks ugly when the labels are right-aligned.\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![axislabelcentertest](https://user-images.githubusercontent.com/22547689/52846259-75a93180-3109-11e9-8981-6211f19affff.png)\r\n\r\n```\r\nMatplitlib version: 3.0.2\r\nTraceback (most recent call last):\r\n\r\n  File \"\u003cipython-input-17-ff49df94c4af\u003e\", line 1, in \u003cmodule\u003e\r\n    runfile('/home/christoffer/Dropbox/Div/axislabelcentertest.py', wdir='/home/christoffer/Dropbox/Div')\r\n\r\n  File \"/home/christoffer/anaconda3/lib/python3.7/site-packages/spyder_kernels/customize/spydercustomize.py\", line 668, in runfile\r\n    execfile(filename, namespace)\r\n\r\n  File \"/home/christoffer/anaconda3/lib/python3.7/site-packages/spyder_kernels/customize/spydercustomize.py\", line 108, in execfile\r\n    exec(compile(f.read(), filename, 'exec'), namespace)\r\n\r\n  File \"/home/christoffer/Dropbox/Div/axislabelcentertest.py\", line 16, in \u003cmodule\u003e\r\n    ax.yaxis.set_tick_params(horizontalalignment='left')\r\n\r\n  File \"/home/christoffer/anaconda3/lib/python3.7/site-packages/matplotlib/axis.py\", line 852, in set_tick_params\r\n    kwtrans = self._translate_tick_kw(kw, to_init_kw=True)\r\n\r\n  File \"/home/christoffer/anaconda3/lib/python3.7/site-packages/matplotlib/axis.py\", line 917, in _translate_tick_kw\r\n    % (key, kwkeys))\r\n\r\nValueError: keyword horizontalalignment is not recognized; valid keywords are ['size', 'width', 'color', 'tickdir', 'pad', 'labelsize', 'labelcolor', 'zorder', 'gridOn', 'tick1On', 'tick2On', 'label1On', 'label2On', 'length', 'direction', 'left', 'bottom', 'right', 'top', 'labelleft', 'labelbottom', 'labelright', 'labeltop', 'labelrotation', 'grid_agg_filter', 'grid_alpha', 'grid_animated', 'grid_antialiased', 'grid_clip_box', 'grid_clip_on', 'grid_clip_path', 'grid_color', 'grid_contains', 'grid_dash_capstyle', 'grid_dash_joinstyle', 'grid_dashes', 'grid_drawstyle', 'grid_figure', 'grid_fillstyle', 'grid_gid', 'grid_in_layout', 'grid_label', 'grid_linestyle', 'grid_linewidth', 'grid_marker', 'grid_markeredgecolor', 'grid_markeredgewidth', 'grid_markerfacecolor', 'grid_markerfacecoloralt', 'grid_markersize', 'grid_markevery', 'grid_path_effects', 'grid_picker', 'grid_pickradius', 'grid_rasterized', 'grid_sketch_params', 'grid_snap', 'grid_solid_capstyle', 'grid_solid_joinstyle', 'grid_transform', 'grid_url', 'grid_visible', 'grid_xdata', 'grid_ydata', 'grid_zorder', 'grid_aa', 'grid_c', 'grid_ls', 'grid_lw', 'grid_mec', 'grid_mew', 'grid_mfc', 'grid_mfcalt', 'grid_ms', 'grid_aa', 'grid_c', 'grid_ls', 'grid_lw', 'grid_mec', 'grid_mew', 'grid_mfc', 'grid_mfcalt', 'grid_ms']\r\n```\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\nI expect the alignment of the y-axis tick labels to change.\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 18.04\r\n  * Matplotlib version: 3.0.2\r\n  * Matplotlib backend (`print(matplotlib.get_backend())`): Qt5Agg\r\n  * Python version: 3.7.1\r\n  * Jupyter version (if applicable):\r\n  * Other libraries: Numpy\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\nInstalled via conda.\r\n","author":{"url":"https://github.com/oestfeldt","@type":"Person","name":"oestfeldt"},"datePublished":"2019-02-15T09:12:41.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/13440/matplotlib/issues/13440"}
