echasrts定义折线图legend的样式-优化

option = {
    title: {
        text: '折线图堆叠'
    },tooltip: {
        trigger: 'axis'
    },//定义折线图legend的形状哈
    legend: {
        itemWidth: 10,itemHeight: 1,itemGap: 10,data:[  
            {name:'邮件营销',icon:'rect'},{name:'联盟广告',{name:'视频广告',{name:'直接访问',{name:'搜索引擎',icon:'rect'}
        ],},grid: {
        left: '3%',right: '4%',bottom: '3%',containLabel: true
    },toolbox: {
        feature: {
            saveAsImage: {}
        }
    },xAxis: {
        type: 'category',boundaryGap: false,data: ['周一','周二','周三','周四','周五','周六','周日']
    },yAxis: {
        type: 'value'
    },series: [
        {
            name: '邮件营销',type: 'line',stack: '总量',data: [120,132,101,134,90,230,210]
        },{
            name: '联盟广告',data: [220,182,191,234,290,330,310]
        },{
            name: '视频广告',data: [150,232,201,154,190,410]
        },{
            name: '直接访问',data: [320,332,301,334,390,320]
        },{
            name: '搜索引擎',data: [820,932,901,934,1290,1330,1320]
        }
    ]
};

注意

通过 data:[
    {name:'邮件营销',icon:'rect'}
],//分别修改legend格式 ，缺省则为默认

还可以定义其他的形状
后面有时间可以看看
然后在回头来写
