Echart 动态生成series数据

要做成页面只传入数据，js生成图表，如下图

下面是js代码

var LineChart = function (ID, title, axisData,seriesData) {
    var myChart = echarts.init(document.getElementById(ID));
    var newData = [];
    var legendData = [];
    for (var i = 0; i < seriesData.length; i++) {
        var lineItem = new serLineItem();
        lineItem.name = seriesData[i].name;
        legendData.push(seriesData[i].name);
        lineItem.data = seriesData[i].data;
        newData.push(lineItem);
    }
    var option = {
        title: {
            text: title,
            subtext: '',
            x: 'center'
        },
        tooltip: {
            trigger: 'axis'
        },
        legend: {
            data: legendData,
            bottom:0
        },
        toolbox: {
            show: true,
            feature: {
                dataZoom: {
                   yAxisIndex: 'none'
                },
                magicType: { type: ['line', 'bar'] },
                restore: {},
                saveAsImage: {}
            }
        },
        xAxis: {
            type: 'category',
            boundaryGap: false,
            data: axisData
        },
        yAxis: {
            type: 'value'
        },
        series: newData
    };
    myChart.setOption(option);
}
 
var serLineItem = function () {
    return {
        name: '',
        type: 'line',
        data: []
    }
}

前台页面调用

引入相关的js文件

$(document).ready(function () {

　　var axisData= ['周一', '周二', '周三', '周四', '周五', '周六', '周日'];

var seriesData = [{ name: '直接访问', data: [320, 302, 301, 334, 390, 330, 320] },
{name: '邮件营销', data: [120, 132, 101, 134, 120, 230, 210]},
{name: '联盟广告', data: [220, 182, 191, 234, 290, 330, 310]},
{name: '视频广告', data: [150, 212, 201, 154, 190, 330, 410]},
{ name: '搜索引擎', data: [820, 832, 901, 934, 1290, 1330, 1320] }];

LineChart('main', '访问', axisData, seriesData);

}
