|
* background are set through `stroke`, `stroke-width` and `fill` attributes

/**
|
|
* 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`.

* [1, 2],
|
|
* [2, 8]

|
* few settings, see the complete options set below. If the total number of

* data points exceeds the series'
|
|
* [turboThreshold](#series.line.turboThreshold),

* [yAxis](https://api.highcharts.com/highcharts/yAxis) or

|
* 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
|
|

|
* adding and removing items from the collection. Read more under the

* When `true`, the `series`, `xAxis`, `yAxis` and `annotations`
