         * of the point, and the `x` value is inferred.
         * 
         *  ```js
         *     data: [
         *         [0, 7],

         *  ```
         * 
         * 3.  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.waterfall.turboThreshold),

         * 1.  An array of arrays with 3 or 2 values. In this case, the values
         * correspond to `x,y,z`. If the first value is a string, it is applied

         * 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.
         *
