Highcharts 绘制箱式图如何在数组后面添加异常值

[lishan]

想要的效果就是两组数据，异常值分别在两组数据对应的上面，目前是只能显示在一起，我对代码做了一个拓展

(function (H) {
	H.seriesTypes.boxplot.prototype.pointArrayMap = ['low', 'q1', 'median', 'q3', 'high', 'outlier'];

	H.seriesTypes.boxplot.prototype.toYData = function (point) {
		return [point.low, point.q1, point.median, point.q3, point.high, point.outlier];
	};

	// draw lines after default drawPoints is called:
	H.wrap(H.seriesTypes.boxplot.prototype, 'drawPoints', function (p) {
		p.call(this);
		var chart = this.chart,
				r = chart.renderer,
				xAxis = this.xAxis,
				yAxis = this.yAxis,
				x, y;

		// for each point, draw line:
		H.each(this.points, function (p, i) {
				x = p.shapeArgs.x;
				// y = p.meanPlot;
				var _x = p.shapeArgs.width/2;
			
				if(p.outlier && p.outlier.length > 0){ // 异常值存在
					for(var i = 0;i < p.outlier.length; i++){
						if(p.outlier[i]){
								if(p['outlierPoint' + (i + 1)]){
									p['outlierPoint' + (i + 1)].attr({
										x: x+_x,
										y: p.outlier[i]
									});
								}else{
									p['outlierPoint' + (i + 1)] = r.circle(x+_x, p.outlier[i] , 4).attr({
										fill: p.color,
										stroke: '#fff',
										'stroke-width': 1,
										zIndex: 100
									}).add(p.series.group);
								}
						}
					}
				}
		});
	});
})(Highcharts)
