Currently it calls draw().\nSo then if I change a property of the figure, the figure gets marked as stale, draw_idle is called, draw_idle calls draw, which resets the figure as non-stale.\n","author":{"url":"https://github.com/mdehoon","@type":"Person","name":"mdehoon"},"datePublished":"2015-07-24T09:54:54.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/4780/matplotlib/issues/4780"}
