 * An array of data points for the series. For the `arearange` series type,

 * 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.

 *     ]
 *     ```
 *
 * 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.arearange.turboThreshold),
