             *
             * A special case is configuration objects that take arrays, for example
             * [xAxis](https://api.highcharts.com/highcharts/xAxis),
             * [yAxis](https://api.highcharts.com/highcharts/yAxis) or
             * [series](https://api.highcharts.com/highcharts/series). For these
             * collections, an `id` option is used to map the new option set to an
             * existing object. If an existing object of the same id is not found, the
             * corresponding item is updated. So for example, running `chart.update`
             * with a series item without an id, will cause the existing chart's series
             * with the same index in the series array to be updated. When the
             * `oneToOne` parameter is true, `chart.update` will also take care of
             * adding and removing items from the collection. Read more under the
             * parameter description below.
             *
             * Note that when changing series data, `chart.update` may mutate the passed
             * data options.
             *
             * See also the
             * [responsive option set](https://api.highcharts.com/highcharts/responsive).
             * Switching between `responsive.rules` basically runs `chart.update` under
             * the hood.

             *        collections will be updated one to one, and items will be either
             *        added or removed to match the new updated options. For example,
             *        if the chart has two series and we call `chart.update` with a
             *        configuration containing three series, one will be added. If we

             *        an empty `series` array will remove all series, but leaving out
             *        the`series` property will leave all series untouched. If the
             *        series have id's, the new series options will be matched by id,
             *        and the remaining ones removed.

        /**
         * 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`.

             *        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.

         *    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,

         *    calculated, either starting at 0 and incremented by 1, or from

         *    has categories, these will be used. Example:
         *    ```js

         *
         * 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, 9],
         *        [1, 2],

         *    ]
         *    ```
         *
         * 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'

         *    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, 10],
         *        [1, 9],
         *        [2, 3]
         *    ]
         *    ```
         *
         * 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.areaspline.turboThreshold), this option is not

         *    `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],

         *    ]
         *    ```

         *    few settings, see the complete options set below. If the total number of
         *    data points exceeds the series'

         *
         * The default algorithms are as follows:
         *
         * `straight`:      Draws a straight line between the connecting
         *                  points. Does not avoid other points when drawing.

         * `simpleConnect`: Finds a path between the points using right angles
         *                  only. Takes only starting/ending points into
         *                  account, and will not avoid other points.
         *
         * `fastAvoid`:     Finds a path between the points using right angles
         *                  only. Will attempt to avoid other points, but its
         *                  focus is performance over accuracy. Works well with
         *                  less dense datasets.

         * `Highcharts.Pathfinder.prototype.algorithms`
         * object before the chart has been created.
         *
         * The default algorithms are as follows:
         *
         * `straight`:      Draws a straight line between the connecting
         *                  points. Does not avoid other points when drawing.
         *
         * `simpleConnect`: Finds a path between the points using right angles
         *                  only. Takes only starting/ending points into
         *                  account, and will not avoid other points.
         *
         * `fastAvoid`:     Finds a path between the points using right angles
         *                  only. Will attempt to avoid other points, but its
         *                  focus is performance over accuracy. Works well with
         *                  less dense datasets.
