I'd like to specify the figure size directly in a metric unit, nominally centimeters (or millimeters, no difference). In most EU countries metric is the norm. I only have to deal with inches when looking at monitor sizes, printing, and matplotlib :(\r\n\r\nI've found at least two issues about this: #1369 and the more generic #9226.\r\n\r\nOf course, having support for generic unit specifiers would be nice, but I'm not entirely satisfied by the extra complexity of #9226. I'm also thorn about (size, unit) tuples, because I don't ever think I'm going to specify the figure size in AU, or picometers. Cm is regularly used for anything that fits paper.\r\n\r\nI see two cases where inches are specified in the rc:\r\n\r\n- figure.figsize\r\n- savefig.pad_inches\r\n\r\nIn the api, there is the figsize kwarg, I guess a pad_inches kwarg, and the set_size_inches method.\r\n\r\nWhat abound the KISS approach: add a figsize_cm kwarg, pad_cm, and the set_size_cm method, and the two respective rcParams? Fully backward compatible, and allows metric countries to get by easily.\r\n\r\nI could easily contribute such a patch.","author":{"url":"https://github.com/wavexx","@type":"Person","name":"wavexx"},"datePublished":"2018-10-04T15:02:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":26},"url":"https://github.com/12402/matplotlib/issues/12402"}
