Question

效果图：

图表的配置：
var chart = Highcharts.chart('container',{

chart: {
    type: 'column'
},
"plotOptions": {
    column: {
        dataLabels: {
            enabled: true,

            formatter: function(){
                if(this.y>0){
                    return "<spam style='color:#39C46E'>+"+this.y+"%</span>"
                }else{
                    return "<spam style='color:#F5475B'>"+this.y+"%</span>"
                }
            }
        }
    }
