Grouped box plot with multiple variables

[guybrettrobertson]

Is there a way to create a grouped box plot with multiple grouping variables using {echarts4r}?

I would like to create a grouped box plot with multiple variables comparable to this {ggplot2} plot: https://www.r-graph-gallery.com/265-grouped-boxplot-with-ggplot2.html

I have tried the following:

variety = rep(LETTERS[1:7], each=40)
treatment = rep(c("high","low"),each=20)
note = seq(1:280)+sample(1:150, 280, replace=T)

data.frame(variety, treatment ,  note) |>
  echarts4r::group_by(variety, treatment) |>
  echarts4r::e_charts() |>
  echarts4r::e_boxplot(note) |>
  echarts4r::e_legend()

But it gives me this:

I have also tried using e_add_nested but it doesn't seem to work for boxplots.

I just noticed that has already come up in issue 253 but no clean solution was available at the time. Have any developments been made on this?

I would love this feature too. I've been using bar charts as a workaround (where the multiple grouping works as expected), but often boxplots are just so much more appropriate. :)
