This works without problems with the PDF backend, also using Tex to render text does not make a difference.\nusing this Python code:\n\n```\nimport matplotlib.pyplot as plt\nfig = plt.figure(figsize=(2,2))\nax = fig.add_subplot(111)\nax.plot([1,2],[5,7])\nax.set_xticks([1,2])\nax.set_xticklabels([\"up\",\"down\"])\nax.set_xlim([0,3]) # get the ticks closer together\nplt.tight_layout()\nfig.savefig(\"ticks_std.pdf\")\nfig.savefig(\"ticks_std.pgf\")\nfor lab in ax.xaxis.get_ticklabels():\n    lab.set_verticalalignment(\"baseline\")\nfig.savefig(\"ticks_base.pdf\")\nfig.savefig(\"ticks_base.pgf\")\nfor lab in ax.xaxis.get_ticklabels():\n    lab.set_verticalalignment(\"top\")\nfig.savefig(\"ticks_top.pdf\")\nfig.savefig(\"ticks_top.pgf\")\n```\n\n... and this Tex document:\n\n```\n\\documentclass{standalone}\n\\usepackage{tikz}\n\\begin{document}\n\\begin{tabular}{ccc}\n\\input{ticks_std.pgf} \u0026 \\input{ticks_base.pgf} \u0026 \\input{ticks_top.pgf} \\\\\n\\includegraphics{ticks_std.pdf} \u0026 \\includegraphics{ticks_base.pdf} \u0026 \\includegraphics{ticks_top.pdf}\n\\end{tabular}\n\\end{document} \n```\n\nproduces this:\n![ticks](https://cloud.githubusercontent.com/assets/769593/6227474/85287de2-b6a0-11e4-9b64-0f6919e9a298.jpg)\n\nOne possible solution could be to use the baseline alignment with some additional padding depending on the font size.\n","author":{"url":"https://github.com/jowr","@type":"Person","name":"jowr"},"datePublished":"2015-02-17T11:30:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/4115/matplotlib/issues/4115"}
