violin plot not showing x-axis data labels (only numbers)

I have tried to render a seaborn violin plot in bokeh. All works fine but it does not show the labels on the x axis. Only numbers show up. I have also tried using the names parameters and passing a list (which works on Seaborn) but my labels do not show up.

This is my code:

g=sns.violinplot(df.Rating.dropna(), df.Line, color=“coolwarm_r”)

show(mpl.to_bokeh(name=“violin”))

here is the link to the seaborn version (with labels on x axis) http://www.logeeka.com/cruises/violinplots.html

here is the link on the bokeh version (numbers instead of labels) http://www.logeeka.com/cruises/violin.html

Thanks for your help
