Highcharts series中name的颜色

Question

用Highcharts画了张曲线图，由于风格需要，将图的背景颜色设为了黑色，其他的字符颜色设为了白色，现在，title,x-title,y-title以及x轴和y轴以及曲线颜色都设置为合适的颜色了，唯独series中的那个name的颜色，没办法设置，大手们给指点下如何搞。代码如下：var chart2;
        chart2 = new Highcharts.Chart({
            chart: {
             backgroundColor: '#3C3C3C',
                renderTo: 'container2',
                type: 'bar'
            },
            title: {
                text: title,
                style: {
                 color:'#FFFFFF'
                }
            },
            xAxis: {
                categories: x_value,
                title: {
                    text: x_title,
                 style: {
                 color:'#FFFFFF'
                 }
                },
                labels:{                    
                 style: {font: 'normal 10px 宋体',
                 color:'#FFFFFF'
                 }
                }
            },
            yAxis: {
                min: 0,
                title: {
                    text: y_title,
                    align: 'high',
                 style: {
                 color:'#FFFFFF'
                 }
                },
                labels:{                    
                 style: {font: 'normal 10px 宋体',
                 color:'#FFFFFF'
                 }
                }
            },
            tooltip: {
             enabled: false,
                formatter: function() {
                    return ''+
                        this.series.name +': '+ this.y;
                }
            },
            plotOptions: {
                bar: {
                 color:'#EA7500',
                    dataLabels: {
                        enabled: false
                    }
                }
            },
            credits: {
                enabled: false
            },
            series: [{
                name: kpi_name,
                data: y_value,
            }]
        });

Answer 1

貌似代码贴成bar图了，不是曲线图了，这个不影响

Answer 2

highcharts可以在里面加html标签的  你想改变series中那么的颜色可以这样写：
                name: '<b style="color:red">北京</b>',
                            series: [{
                                name:'<b style="color:red">'+ kpi_name+'</b>',
                                data: y_value,
                            }]
