Wouldn't it be more useful to factor that out into a separate method (`coord`?) giving access to `x, y, z = proj3d.inv_transform(xd, yd, z, self.M)`? `format_coord` would then simply convert that to the formatted string.\n\nThe question of how to extract these coordinates has been asked a few times on SO:\n\nhttp://stackoverflow.com/questions/6748184/matplotlib-plot-surface-get-the-x-y-z-values-written-in-the-bottom-right-cor\nhttp://stackoverflow.com/questions/28954611/how-to-extract-3d-mouse-coordinate-on-mouse-click-in-matplotlib-in-python\n\nand aside from duplicating the code within `format_coord` the best we can do is parse the values out of the generated string.\n","author":{"url":"https://github.com/ndawe","@type":"Person","name":"ndawe"},"datePublished":"2015-04-14T02:58:51.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/4334/matplotlib/issues/4334"}
