For example, the following code\n\n```\nimport matplotlib.pyplot as plt\nimport numpy as np\n\nfig = plt.figure()\nax = plt.subplot()\nax.set_xlim(0, 4)\nax.set_xticks([0, 0.5, 1, 2, 3.5, 4])\nax.set_xticklabels(['a','b','c', '2', '3.5', '4']) \nax.set_ylim(0, 8)\nax.set_yticks([0, 0.5, 1, 2, 3.5, 4, 8])\nplt.savefig('before_boxplot.png')\n```\n\nproduces this plot\n![before_boxplot](https://f.cloud.github.com/assets/4099759/2495190/04bf9acc-b2ec-11e3-97c3-24aef157e144.png)\nBut when I execute this code next\n\n```\ny1 = np.random.normal(10, 3, 20)\ny2 = np.random.normal(3, 1, 20)\nax.boxplot([y1, y2], positions = [1,2])\nplt.savefig('after_boxplot.png')\n```\n\nthe plot changes to\n![after_boxplot](https://f.cloud.github.com/assets/4099759/2495196/22b92836-b2ec-11e3-9cde-916fb2f5d196.png)\nThree things changed:\n1) The x-axis limits used to be 0 to 4.  They are now roughly 0.5 to 2.5.\n2) The tick marks used to be at [0, 0.5, 1, 2, 3.5, 4].  They are now at [1, 2].\n3) The tick mark labels used to be ['a','b','c', '2', '3.5', '4'].  They are now ['a', 'b'].  Based on the changes in (1) and (2) I would have expected the tick mark labels to be ['c', '2'].\n\nThe obvious work around is to set these parameters after you have called `axes.boxplot()`.  However, reseting the axes is not consistent with `axes.plot()`, `axes.bar()`, `axes.imshow()`, or any other plotting method I have used.  Other methods respect the user specified x limits and tick marks.  This behavior also is not consistent with the y-axis behavior in boxplot. Boxplot respected the user specified y limits and tick marks. \n\nI am working with Matplotlib 1.3.0.\n","author":{"url":"https://github.com/breedlun","@type":"Person","name":"breedlun"},"datePublished":"2014-03-24T00:48:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/2921/matplotlib/issues/2921"}
