                radius : '55%',

                        shadowBlur: 10,
                        shadowOffsetX: 0,
                        shadowColor: 'rgba(0, 0, 0, 0.5)'
                    }
                }
            }
        ]
    };
    var myChart = echarts.init(d3.select("#main").node());
    myChart.setOption(option);
    //更新option数据
    option.series[0].data.push({value:234, name:'联盟广告'});
    option.legend.data.push('联盟广告');
    myChart.setOption(option);
