option = {
tooltip: {

formatter: "{a} <br/>{b}: {c} ({d}%)"
},
legend: {
orient: 'vertical',
x: 'left',
data:['直接访问','邮件营销','联盟⼴告','视频⼴告','搜索引擎']
},
series: [
{
name:'访问来源',
type:'pie',
radius: ['50%', '70%'],
avoidLabelOverlap: false,
label: {
normal: {
show: false,
position: 'center'
},
emphasis: {
show: true,
textStyle: {
fontSize: '30',
fontWeight: 'bold'
}
}
},
labelLine: {
normal: {
show: false
}
},
data:[
{value:335, name:'直接访问'},
{value:310, name:'邮件营销'},
{value:234, name:'联盟⼴告'},
{value:135, name:'视频⼴告'},
{value:1548, name:'搜索引擎'}
]
}
]
};
// 使⽤刚指定的配置项和数据显⽰图表。
myChart.setOption(option);

饼状图实现效果如下：

}
]
};
// 使⽤刚指定的配置项和数据显⽰图表。
