Currently these attributes may be specified on a [discretized scale with 3 categories](https://github.com/plotly/plotly.js/blob/e01a765953a290967bc97b7c72d5a3d9b91f0c03/src/components/annotations/attributes.js#L81-L102). Mainly requesting so we can achieve parity with ggplot2 when converting labels/annotations: ```r qplot(1:10) + ggtitle("Hey there") + theme(plot.title = element_text(size = 40, vjust = 1, hjust = 0.75, debug = T)) ```
