{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Feature request - make it simpler to use full OO interface","articleBody":"I would like to start using the matplotlib OO interface more, as I would prefer to use this when interactive plotting is not needed. It it slightly faster, and behaves more intuitively in terms of reference counting (pyplot keeps a reference to each figure, meaning that if figures are not closed by pyplot, memory goes out of control).\n\nThe reason I don't use it is because it's not easy to remember all the set-up of the canvas and figure:\n\n```\nfrom matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas\nfrom matplotlib.figure import Figure\n\nfig = Figure()\ncanvas = FigureCanvas(fig)\nax = fig.add_subplot(1, 1, 1)\nax.scatter(np.random.random(10), np.random.random(10))\nfig.savefig('test.png')\n```\n\nSo I was wondering whether it would be possible to make `Figure` more intelligent in terms of canvas? The 'ideal' API in my mind would be:\n\n```\nfrom matplotlib.figure import Figure\n\nfig = Figure()\nax = fig.add_subplot(1, 1, 1)\nax.scatter(np.random.random(10), np.random.random(10))\nfig.savefig('test.png')\n```\n\ni.e. I want the figure to just use the default backend (since this is set at the root level of matplotlib, _not_ pyplot). So I would expect the following to work:\n\n```\nimport matplotlib\nmatplotlib.use('Agg')\nfrom matplotlib.figure import Figure\n\nfig = Figure()\nax = fig.add_subplot(1, 1, 1)\nax.scatter(np.random.random(10), np.random.random(10))\nfig.savefig('test.png')\n```\n\nand to use the non-interactive Agg backend.\n\nIs this something that has been considered before?\n","author":{"url":"https://github.com/astrofrog","@type":"Person","name":"astrofrog"},"datePublished":"2012-08-16T13:31:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":17},"url":"https://github.com/1094/matplotlib/issues/1094"}
