/**
 * This is the base series prototype that all other series types inherit from.
 * A new series is initialized either through the
 * [series](https://api.highcharts.com/highcharts/series)
 * option structure, or after the chart is initialized, through
 * {@link Highcharts.Chart#addSeries}.
 *
 * The object can be accessed in a number of ways. All series and point event
 * handlers give a reference to the `series` object. The chart object has a
 * {@link Highcharts.Chart#series|series} property that is a collection of all
 * the chart's series. The point objects and axis objects also have the same
 * reference.
 *
 * Another way to reference the series programmatically is by `id`. Add an id
 * in the series configuration options, and get the series object by
 * {@link Highcharts.Chart#get}.
 *
 * Configuration options for the series are given in three levels. Options for
 * all series in a chart are given in the
 * [plotOptions.series](https://api.highcharts.com/highcharts/plotOptions.series)
 * object. Then options for all series of a specific type
 * are given in the plotOptions of that type, for example `plotOptions.line`.
 * Next, options for one single series are given in the series array, or as
 * arguments to `chart.addSeries`.
 *
 * The data in the series is stored in various arrays.
 *
 * - First, `series.options.data` contains all the original config options for
 *   each point whether added by options or methods like `series.addPoint`.
 *
 * - Next, `series.data` contains those values converted to points, but in case
 *   the series data length exceeds the `cropThreshold`, or if the data is
 *   grouped, `series.data` doesn't contain all the points. It only contains the
 *   points that have been created on demand.
 *
 * - Then there's `series.points` that contains all currently visible point
 *   objects. In case of cropping, the cropped-away points are not part of this
 *   array. The `series.points` array starts at `series.cropStart` compared to
 *   `series.data` and `series.options.data`. If however the series data is
 *   grouped, these can't be correlated one to one.
 *
 * - `series.xData` and `series.processedXData` contain clean x values,
 *   equivalent to `series.data` and `series.points`.
 *
 * - `series.yData` and `series.processedYData` contain clean y values,
 *   equivalent to `series.data` and `series.points`.

     * Apply a new set of data to the series and optionally redraw it. The

     * `updatePoints`), and may later be mutated when updating the chart
     * data.
     *
     * Note the difference in behaviour when setting the same amount of
     * points, or a different amount of points, as handled by the
     * `updatePoints` parameter.
     *
     * @sample highcharts/members/series-setdata/
     *         Set new data from a button
     * @sample highcharts/members/series-setdata-pie/
     *         Set data in a pie
     * @sample stock/members/series-setdata/

     * @function Highcharts.Series#setData
     *
     * @param {Array<Highcharts.PointOptionsType>} data
     *        Takes an array of data in the same format as described under
     *        `series.{type}.data` for the given series type, for example a
     *        line series would take data in the form described under
     *        [series.line.data](https://api.highcharts.com/highcharts/series.line.data).
     *
     * @param {boolean} [redraw=true]
     *        Whether to redraw the chart after the series is altered. If
     *        doing more operations on the chart, it is a good idea to set
     *        redraw to false and call {@link Chart#redraw} after.
     *
     * @param {boolean|Partial<Highcharts.AnimationOptionsObject>} [animation]
     *        When the updated data is the same length as the existing data,
     *        points will be updated by default, and animation visualizes
     *        how the points are changed. Set false to disable animation, or
     *        a configuration object to set duration or easing.
     *
     * @param {boolean} [updatePoints=true]
     *        When this is true, points will be updated instead of replaced
     *        whenever possible. This occurs a) when the updated data is the
     *        same length as the existing data, b) when points are matched
     *        by their id's, or c) when points can be matched by X values.
     *        This allows updating with animation and performs better. In
     *        this case, the original array is not passed by reference. Set
     *        `false` to prevent.

/**
 * An array of data points for the series. For the `line` 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, 2],
 *        [2, 8]
 *    ]
 *    ```
 *
 * 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.line.turboThreshold),
 *    this option is not available.
 *    ```js
 *    data: [{
 *        x: 1,
 *        y: 9,
 *        name: "Point2",
 *        color: "#00FF00"
