* @typedef {Object} SVGAttributes An object of key-value pairs for SVG
* attributes. Attributes in Highcharts elements for the most parts
* correspond to SVG, but some are specific to Highcharts, like `zIndex`,
* `rotation`, `rotationOriginX`, `rotationOriginY`, `translateX`,
* `translateY`, `scaleX` and `scaleY`. SVG attributes containing a hyphen
* are _not_ camel-cased, they should be quoted to preserve the hyphen.
*
* @example
* {
* 'stroke': '#ff0000', // basic
* 'stroke-width': 2, // hyphenated
* 'rotation': 45 // custom
* 'd': ['M', 10, 10, 'L', 30, 30, 'z'] // path definition, note format

* Apply native and custom attributes to the SVG elements.

* In order to set the rotation center for rotation, set x and y to 0 and
* use `translateX` and `translateY` attributes to position the element
* instead.

* Attributes frequently used in Highcharts are `fill`, `stroke`,
* `stroke-width`.
*
* @param {SVGAttributes|String} hash - The native and custom SVG
* attributes.
* @param {string} [val] - If the type of the first argument is `string`,
* the second can be a value, which will serve as a single attribute
* setter. If the first argument is a string and the second is undefined,
* the function serves as a getter and the current value of the property
* is returned.
* @param {Function} [complete] - A callback function to execute after
* setting the attributes. This makes the function compliant and
* interchangeable with the {@link SVGElement#animate} function.
* @param {boolean} [continueAnimation=true] Used internally when `.attr` is
* called as part of an animation step. Otherwise, calling `.attr` for an
* attribute will stop animation for that attribute.
*
* @returns {SVGElement|string|number} If used as a setter, it returns the
* current {@link SVGElement} so the calls can be chained. If used as a
* getter, the current value of the attribute is returned.

*
* The common use case is that all charts in the same Highcharts object

* ```js
* // Apply time settings globally
* Highcharts.setOptions({

* });
* // Apply time settings by instance
* var chart = Highcharts.chart('container', {

* series: [{
* data: [1, 4, 3, 5]

* });
*
* // Use the Time object
* console.log(
* 'Current time in New York',
* chart.time.dateFormat('%Y-%m-%d %H:%M:%S', Date.now())
* );
* ```
*
* Since v6.0.5, the time options were moved from the `global` obect to the
* `time` object, and time options can be set on each individual chart.

* or after the chart is initialized, through
* {@link Highcharts.Chart#addSeries}.
*

* 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
* {@link https://api.highcharts.com/highcharts/plotOptions.series|
* 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
* arguements 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

* A generic function to update any element of the chart. Elements can be

* {@link https://api.highcharts.com/highcharts/yAxis|yAxis} or
* {@link https://api.highcharts.com/highcharts/series|series}. For these

* 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.
*
* See also the {@link https://api.highcharts.com/highcharts/responsive|
* responsive option set}. Switching between `responsive.rules` basically
* runs `chart.update` under the hood.

* @param {Boolean} [oneToOne=false]
* When `true`, the `series`, `xAxis` and `yAxis` 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 call
* `chart.update` with one series, one will be removed. Setting 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.

/**
* A full set of chart options to apply as overrides to the general
* chart options. The chart options are applied when the given rule
* is active.
*
* A special case is configuration objects that take arrays, for example
* [xAxis](#xAxis), [yAxis](#yAxis) or [series](#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 item of the same indexupdated. So for example, setting `chartOptions`
* with two series items without an `id`, will cause the existing chart's
* two series to be updated with respective options.
