Force plotly violin plot not to display a violin on zero values

[ndrubins]

Hi,

I have measurements from several groups which I would like to plot as violin plots:

  set.seed(1)
   df <- data.frame(val = c(runif(100,1,5),runif(100,1,5),rep(0,100)),
                    group = c(rep("A",100),rep("B",100),rep("C",100)))

When I use R's ggplot2:

    library(ggplot2)
    ggplot(data = df, aes(x = group, y = val, color = group)) + geom_violin()

I get this plot

But when I try to get the equivalent with R's plotly using:

    library(plotly)
    plot_ly(x = df$group, y = df$val, split = df$group, type = 'violin', box = list(visible = F), points = F, showlegend = T, color = df$group)

I get this plot in which group "C" gets an inflated/artificial violin.

Can I tell plot_ly not to create violin for groups such as "C"?

This is something that should be fixed at the plotly.js level, see plotly/plotly.js#2779
