depictr.raincloud_plot

depictr.raincloud_plot(data, x, group=None, title=None)

Raincloud plot of a numeric variable, optionally split by a group.

A raincloud sets three views of the same distribution side by side: a half-violin density (the “cloud”), a narrow boxplot for the median and quartiles, and the jittered raw points (the “rain”). Seeing the shape, the summary and every observation together guards against the boxplot hiding bimodality or a thin tail (Allen et al., 2021).

Parameters:

• data (pandas.DataFrame) – The data.

• x (str) – Name of the numeric column whose distribution is shown.

• group (str, optional) – A categorical column. Each level gets its own raincloud along the horizontal axis, coloured by the depictr palette. With no group a single raincloud is drawn.

• title (str, optional) – Plot title.

Return type:

plotnine.ggplot
