For now, we could hardcode a mapping in that would work for default font-sizes:\n  - 8 legend entries: `annotation$y \u003c- 0.65` (from manual inspection)\n  - 1 legend entry: `annotation$y \u003c- 0.52` (manual inspection)\n  - -\u003e `annotation$y \u003c- 0.14125 * number_of_legend_items - 0.48` (computed from those two points above)\n  \n  @alexcjohnson, how do you think legend titles will work in the future? a separate attribute inside `legend`?\n- [ ] manual legend positions from ggplot: https://github.com/ropensci/plotly/blob/add-r-cookbook-tests/tests/cookbook-test-suite/legends.R#L109-L122\n\ncc @tdhock , @cpsievert \n","author":{"url":"https://github.com/chriddyp","@type":"Person","name":"chriddyp"},"datePublished":"2015-03-30T19:53:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/195/plotly.R/issues/195"}
