/**
 * An array of data points for the series. For the `boxplot` series
 * type, points can be given in the following ways:
 *
 * 1.  An array of arrays with 6 or 5 values. In this case, the values
 * correspond to `x,low,q1,median,q3,high`. If the first value is a
 * string, it is applied as the name of the point, and the `x` value
 * is inferred. The `x` value can also be omitted, in which case the
 * inner arrays should be of length 5\. Then the `x` value is automatically
 * calculated, either starting at 0 and incremented by 1, or from `pointStart`
 * and `pointInterval` given in the series options.
 *
 *  ```js
 *     data: [
 *         [0, 3, 0, 10, 3, 5],

 *         [2, 6, 9, 5, 1, 3]
 *     ]
 *  ```
 *
 * 2.  An array of objects with named values. The objects are point
 * configuration objects as seen below. If the total number of data
 * points exceeds the series' [turboThreshold](#series.boxplot.turboThreshold),
 * this option is not available.
