Hi @tdwils, this PR is ready for another review. The issue was that the ggplot2 object looked beautiful, but a lot of configurations aren't supported or come out looking quite different when passed through plotly::ggplotly() so I had to make some overall plotly::layout() changes to correct the issue. Let me know how things look on your end!

Hi @tdwils, can you please test one more time given my new commits? Before pursuing a plotly margin solution that is a function of other variables, I think / hope the new fix will work for you. 🤞🏼
