Unlike `imshow()` which really plots the masked data,\n`plot_surface()` only plots the non-masked data.\nHere is an example:\n\n```\nimport numpy as np\nimport pylab as mpl\nfrom mpl_toolkits.mplot3d import axes3d\n\nx = np.arange(1,10,1)\ny = np.arange(1,10,1)\nx,y = np.meshgrid(x,y)\nz = x**3 + y**3 - 500\nz = np.ma.masked_array(z, z\u003c0)\n\ncm = mpl.cm.jet\n\nax1 = mpl.subplot(1,2,1, projection='3d')\nax1.plot_surface(x,y,z,\n                 rstride=1, cstride=1, linewidth=0,\n                 cmap=cm)\n\nax2 = mpl.subplot(1,2,2)\nax2.imshow(z, cmap=cm)\n\nmpl.show()\n```\n","author":{"url":"https://github.com/AndreasMatthias","@type":"Person","name":"AndreasMatthias"},"datePublished":"2011-09-22T20:36:09.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/487/matplotlib/issues/487"}
