Multi level charts axis option

Hi everyone !
I was looking for an option on hvplot to remove the multiple axis labels that appear when plotting multiple groups in a bar chart and display a legend instead. Default behavior is to ignore legend param and display both axis levels as shown in the last plot of the page Bar — hvPlot 0.8.2 documentation (holoviz.org)

The correct option to show a legend instead is to use plot.opts(multi_level=False) option to avoid repeating multiple group labels all over the plot.

I have two questions:

  • Is there a hvplot setting to achieve this ? multi_level=False directly in the hvplot function is not recognized as a valid parameter.
  • Could there be another example in the gallery above showing this method for displaying legend instead of multiple axis labels ? I believe this would help lots of people used to making plots by population in multivariate analysis.

Many thanks
