Adding extra code similar to that for 'set_visible'  makes the code work again.\nI would expect the code to work without the Bug fix code snippets included.\n\n```\n#! coding=utf-8\nimport matplotlib.pyplot as plt\nimport matplotlib.animation as animation\nimport numpy as np\nimport types\n\n#################################################################\n## Bug fix for Quad Contour set not having attribute 'set_visible'\n\n\ndef setvisible(self,vis):\n    for c in self.collections: c.set_visible(vis)\ndef setanimated(self,ani):\n    for c in self.collections: c.set_animated(ani)\n####################################################################\n\nfig = plt.figure()\n\n# Some 2D geo arrays to plot (time,lat,lon)\ndata = np.random.random_sample((20,90,360))\nlat = range(len(data[0,:,0]))\nlon = range(len(data[0,0,:]))\nlons,lats = np.meshgrid(lon,lat)\n\n# ims is a list of lists, each row is a list of artists to draw in the\n# current frame; here we are animating three artists, the image and 2 \n# annotatons (title), in each frame\nims = []\nfor i in range(len(data[:,0,0])):\n    t_step = int(i)\n    im = plt.contourf(lons,lats,data[i,:,:])\n    text = 'title=' + str(i)\n    te = plt.text(90,90,str(text))\n    an = plt.annotate(str(text), xy=(0.45, 1.05), xycoords='axes fraction')\n    #################################################################\n    ## Bug fix for Quad Contour set not having the attributes\n    ## 'set_visible' and 'set_animated'\n    # ** uncomment the following 2 lines to make the code work:**\n#   im.set_visible = types.MethodType(setvisible,im)\n#   im.set_animated = types.MethodType(setanimated,im)\n    im.axes = plt.gca()\n    im.figure = fig\n    ####################################################################\n    ims.append([im,te,an])\n\n#ani = animation.ArtistAnimation(fig, ims, interval=70,repeat_delay=1000, blit=False)\nani = animation.ArtistAnimation(fig, ims)\n## For saving the animation we need ffmpeg binary:\n#FFwriter = animation.FFMpegWriter()\n#ani.save('basic_animation.mp4', writer = FFwriter)\nplt.show()\n```\n","author":{"url":"https://github.com/fabrivelas","@type":"Person","name":"fabrivelas"},"datePublished":"2016-03-10T10:00:22.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/6139/matplotlib/issues/6139"}
