         * 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.cylinder.turboThreshold), this option is not
