/**
 * An array of data points for the series. For the `mappoint` series
 * type, points can be given in the following ways:
 *
 * 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, 1],
 *         [1, 8],
 *         [2, 7]
 *     ]
 *  ```
 *
 * 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.mappoint.turboThreshold),
 * this option is not available.
 *
 *  ```js
 *     data: [{
 *         x: 1,
 *         y: 7,
 *         name: "Point2",
 *         color: "#00FF00"
