All the traces have:\r\n`xaxis: 'x\u003cn\u003e', yaxis: 'y\u003cn\u003e'`\r\nand all the x axes have layout obects:\r\n`xaxis\u003cn\u003e: {anchor: 'y\u003cn\u003e'}`\r\n\r\nWith smarter defaults, I would not have needed to include these x axis objects at all since `'x\u003cn\u003e'` is only ever used with `'y\u003cn\u003e'` in the data. In fact, in principle my y axes should also be anchored to the corresponding x axes... I didn't do that, and it didn't matter here because all the x axes have domain `[0, 1]`, but if I **were** to change some of these domains, then I would be in for some confusion as the y axes wouldn't move as I would expect.\r\n\r\nThis would not be backward compatible, so I guess should be included in v2.0 if we do it, but I can't really think of a situation where people would be depending on the existing defaults.","author":{"url":"https://github.com/alexcjohnson","@type":"Person","name":"alexcjohnson"},"datePublished":"2016-11-25T23:22:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/1200/plotly.js/issues/1200"}
