/**
 * An array of data points for the series. For the `errorbar` series

 *
 * 1.  An array of arrays with 3 or 2 values. In this case, the values
 * correspond to `x,low,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 2\. 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, 10, 2],
 *         [1, 1, 8],
 *         [2, 4, 5]
 *     ]
 *  ```
 *
 * 2.  An array of objects with named values. The following snippet shows only a
 * few settings, see the complete options set below. If the total number of data
 * points exceeds the series' [turboThreshold](#series.errorbar.turboThreshold),
 * this option is not available.
 *
