{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Pick events broken in log axes","articleBody":"Handling pick events does not work on logarithmic axes. See the example below. As long as the line statement `ax.set_xscale('log')` is commented out, clicking on the polygons created by `axvspan` xauses them to change from gray to red. Uncomment that line to make the x axis logarithmic, and clicking on the polygons has either no effect or is misdirected to the far-left polygon only.\n\n``` python\n    from matplotlib import pyplot as plt\n    fig = plt.figure()\n    ax = fig.add_subplot(111)\n    ax.set_xlim(1, 10)\n    for i in range(1, 10, 3):\n        ax.axvspan(i, i + 1, color='gray', picker=True)\n\n    # uncomment this line to break the picker\n    # ax.set_xscale('log')\n\n    def onpick(event):\n        event.artist.set_color('red')\n        fig.canvas.draw()\n\n    fig.canvas.mpl_connect('pick_event', onpick)\n    plt.show()\n```\n\nTested on version 1.4.0 and master as of 04496b056f1995e1c54e6a5feb5be9256e2d8e9b on Mac OS X Mavericks.\n\n[TAC edited for formatting]\n","author":{"url":"https://github.com/lpsinger","@type":"Person","name":"lpsinger"},"datePublished":"2014-09-19T01:35:43.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/3540/matplotlib/issues/3540"}
