Highcharts饼状图，如何在一个页面显示多个饼？

    $.getJSON("/api/xinxiguanli/jianquhuafen/counts", function (res) {
        for(var i=0;i<res.length;i++){

                //console.log(tmp);
                if (tmp.jianqu==obj.jianqu){
                    break;
                }
                tmp="";
            }
            if (tmp==""){
                CountArray.push({
