Half violin plot in Julia

Question

I would like to plot a half violin plot instead of a full violin plot. Here is some reproducible code which creates full violin plots:

using StatsPlots
StatsPlots.violin(repeat(["A", "B"],outer=100),randn(300))

Output:

As you can see it creates a full violin plot. In the docs I can't find anything about half violin plots. So I was wondering if anyone know if it is possible to creat half violin plots in Julia?

Answer 1

The optional argument side defaults to :both, so to have a half violin, use :left or :right like this:

using StatsPlots
StatsPlots.violin(repeat(["A", "B"],outer=100),randn(300), side = :left)

Output:

Note that this behavior is not currently documented in the 'violin' method docs, but it is used in the examples.
