修改fillColor中的marker。 代码段：

beforeGeneration: function(options)
{
    var throughTargetPercent = this.getReportVariable("through_target_percent"); 

    for(var i = 0 ; i < options.series.length ; i++){
        var data = options.series[i].data;
        var len = data.length;
        for (var j=0; j < len; j++){
             if(data[j].y < throughTargetPercent) {
                data[j]= {
                    y: data[j].y,
                    marker: {
                        fillColor: "yellow" 
                    }
                }
            }
        } 
    }
},
