Hi there 
I came across a problem regarding plotly violin plots in R - it can be seen in the first one of the examples on https://plot.ly/r/violin/ (“Basic Violin Plot”).
If I investigate the dataset, the lowest value for “total_bill” is 3.07:
min(df$total_bill) # 3.07
However, the lower end of the violin plot even reaches below zero on the x-axis. Is this result a bug or expected - and (how) can it be “fixed”?
I found another user who identified this as a problem: https://stackoverflow.com/questions/55011840/force-plotly-violin-plot-not-to-display-a-violin-on-zero-values
Unfortunately, I can’t use the solution of hiding a certain group, as I do want to show the existing values within this very same group (I have this problem in the upper as well as in the lower area of my plots, but I do want to plot the existing values in the middle).
I’d appreciate any help and/or clarification 
Best regards,
david
