This discussion made me think of violin plots that aims to address this problem using a box plot with a rotated kernel density plot … This R tutorial describes how to create a violin plot using R software and ggplot2 package.. violin plots are similar to box plots, except that they also show the kernel probability density of the data at different values.Typically, violin plots will include a marker for the median of the data and a box indicating the interquartile range, as in standard box plots. The example below shows the actual data on the left, with too many points to really see them all, and a violin plot on the right. Let’s connect! 1. Additionally Tableau cannot use the # Orders as an action filter because it is a Measure (aggregate) – and only dimensions can be passed as filters in actions.
