/**

|
|
* An array of data points for the series. For the `variablepie` series type,
|
||
|
|
* points can be given in the following ways:
|
||
|
|
*
|
||
|
|
* 1. An array of arrays with 2 values. In this case, the numerical values will
|
||
|
|
* be interpreted as `y, z` options. Example:
|
||
|
|
* ```js
|
||
|
|
* data: [
|
||
|
|
* [40, 75],
|
||
|
|
* [50, 50],
|
||
|
|
* [60, 40]
|
||
|
|
* ]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* 2. 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.variablepie.turboThreshold), this option is not
|
||
|
|
* available.
|
||
|
|
* ```js
|
||
|
|
* data: [{
|
||
|
|
* y: 1,
|
||
|
|
* z: 4,
|
||
|
|
* name: "Point2",
|
||
|
|
* color: "#00FF00"
|
||
|
|
* }, {
|
||
|
|
* y: 7,
|
||
|
|
* z: 10,
|
||
|
|
* name: "Point1",
|
||
|
|
* color: "#FF00FF"
