Violin Plot Tool

The Violin Plot tool shows the distribution of a single numeric variable, and conveys the density of the distribution based on a kernel smoother that indicates the density of values (via width) of the numeric field. The inner portion of each violin is a box and whisker plot of the data, where the bottom and top of the inner box are at the first and third quartiles, and the white circle inside the box is at the median for the measure. The vertical bars that extend above and below the box indicate the range of the data that is within 1.5 times the interquartile range (where the interquartile range is the difference between the values of the third and first quartiles).

In addition to concisely showing the nature of the distribution of a numeric variable, violin plots are an excellent way of visualizing the relationship between a numeric and categorical variable by creating a separate violin plot for each value of the categorical variable.
