Javascript 如何删除highcharts中的渲染圆？

我已经渲染了一组圆。但放大后我需要删除它们。我该怎么做

下面是渲染圆的代码

var allPoints = localStorage.getItem('points');
//console.log(allPoints);
if(allPoints !== null) {
    var allPointsDetail = JSON.parse(allPoints);
    _.each(allPointsDetail, function(pointDetail, key) {
        var pointCordinate =[];
        pointCordinate[0] = pointDetail['x'];
        pointCordinate[1] = pointDetail['y'];
        RP.drawReportingPoints(pointCordinate,pointDetail);
    });
}

同样，放大后，我做了这么多

xAxis: {
    events: {
        afterSetExtremes: function(event){
            if (this.getExtremes().dataMin < event.min){
                var top_position =  RP.chart.yAxis[0].toPixels(RP.$valueInput.val());
                RP.$handleContainer.css('top', top_position);
                var allPoints = localStorage.getItem('points');

                // allPoints give points detail which is stored in localStorage.these point should remove from chart which was drawn before

            }
        }
    }
}

xAxis:{
活动：{
AfterSetExtrems:函数（事件）{
if（this.getExtremes（）.dataMin

提前感谢。

开始时，您能否将示例复制为实况演示？您是否使用以下方法绘制这些圆圈：？是标记。我正在使用渲染器.circle。问题已经解决了，你是怎么解决的@纳比纳
