I had hoped `v1.7.0` would solve this, but unfortunately I just updated, and the problem persists.\n\n![plotly_legend_resize](https://cloud.githubusercontent.com/assets/837910/13959365/d614c40c-f021-11e5-99ee-7323b62aece7.gif)\n\nI am happy to attempt to tackle this if desired.  I see on [line](https://github.com/plotly/plotly.js/blob/master/src/components/legend/draw.js#L223) where it checks for `firstRender` to draw the legend.  I'm wondering if we can handle by just removing this `firstRender` check.\n","author":{"url":"https://github.com/timelyportfolio","@type":"Person","name":"timelyportfolio"},"datePublished":"2016-03-22T16:36:37.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/348/plotly.js/issues/348"}
