Hi @cpsievert, any progress on this? Cheers

Yes, I am only using `knitr` to knit to a markdown document. You can see [here](https://raw.githubusercontent.com/Alanocallaghan/testalt/master/test.md) that `knitr::knit` overwrites the `fig.cap` as the title attribute of the `img` tag when...

The reason I'm knitting to a markdown doc rather than html directly is because it's part of a jekyll site setup, fwiw. Part of a carpentries lesson.

No worries, fyi there are a few similar things hanging around in the documentation, eg https://plot.ly/javascript/reference/#bar-marker-colorbar-tickvalssrc

Google maps uses dark text with a white outline, while white text with a dark outline also works. It's the most effective way to make text readable on any background...

Depends on #38 as xgap only works for heatmaps, and ggplotly only converts to heatmaps when numeric (I think)

No, I think it's pretty fundamental to how plotly.js handles heatmaps. It would be nice to get categorical heatmap support in plotly.js but I suspect that's a big ask! BTW,...

I was just passing hovertext in the wrong format! Should be up and running with this in a few days

Works in plot_method = "plotly", still broken in ggplotly.
