18.1.8  Whisker boxes

A boxwhisker is a graphical view of the quartiles of a list of numbers. The boxwhisker consists of a line segment from the the minimum of the list to the first quartile, leading to a rectangle from the first quartile to the third quartile, followed by a line segment from the third quartile to the maximum of the list. The rectangle contains a vertical segment indicating the median, and the two line segments will contain vertical lines indicating the first and ninth decile.

The boxwhisker or mustache command creates a boxwhisker for a list.

Example

boxwhisker([-1,1,2,2.2,3,4,-2,5])
