API

boxPlot(values)

values

Type: number[]

An array of values to compute the box plot for.

Return value

maximum

Type: number

The largest value that is not an outlier. An outlier is a number that is greater than 1.5x the difference between the upper and lower quartile added to the upper quartile.

upperQuartile

Type: number

The median of the values after the middle number(s).

median

Type: number

The median of all of the values.

lowerQuartile

Type: number
