* 1. An array of numerical values. In this case, the numerical values will be
* interpreted as `y` options. The `x` values will be automatically
* 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
* available.
