     * axis units in either direction. So for example on a horizontal X

     * random position between 0.24 units to the left and 0.24 units to the

     * 0.5 will fill up the bin and make the data appear continuous.

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

 * 1. An array of numerical values. In this case, the numerical values will be

 *    calculated, either starting at 0 and incremented by 1, or from
 *    `pointStart` and `pointInterval` given in the series options. If the axis
 *    has categories, these will be used. Example:
 *    ```js
 *    data: [0, 5, 3, 5]
 *    ```
 *
 * 2. An array of arrays with 2 values. In this case, the values correspond to
 *    `x,y`. If the first value is a string, it is applied as the name of the
 *    point, and the `x` value is inferred.
 *    ```js
 *    data: [
 *        [0, 0],
 *        [1, 8],
 *        [2, 9]
 *    ]
 *    ```
 *
 * 3. 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.scatter.turboThreshold), this option is not
 *    available.
