Box and whiskers with the following config options:

    config = {
        colors: ['#eee'], // array of colours (one if you want all one colour)
        fixedScale: null, // pass in a fixed scale e.g. [0, 100]
        customColor: true, // boolean if using `colors` 
        boxWidth: null, // null or number for set width e.g. 30
