/**
|
|
* An array of data points for the series. For the `streamgraph` 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, 9],
|
|
* [1, 7],
|
|
* [2, 6]
|
|
* ]
|
|
* ```
|
|
*
|
|
* 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.area.turboThreshold),
|
|
* this option is not available.
|
|
* ```js
|
|
* data: [{
|
|
* x: 1,
|
|
* y: 9,
|
|
* name: "Point2",
|
|
* color: "#00FF00"
|

* y: 6,
