         * An array of data points for the series. For the `solidgauge` 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. Example:
         * 
         *  ```js
         *  data: [0, 5, 3, 5]
         *  ```
         * 
         * 2.  An array of objects with named values. The objects are point
         * configuration objects as seen below. If the total number of data
         * points exceeds the series' [turboThreshold](#series.solidgauge.turboThreshold),
         * this option is not available.
         * 
         *  ```js
         *     data: [{
         *         y: 5,
         *         name: "Point2",
         *         color: "#00FF00"
