具体代码:

单柱状图,只显示一个

  function echarts_1(data) {

            ]

        // 使用刚指定的配置项和数据显示图表。
        myChart.setOption(option);
        window.addEventListener("resize", function () {
            myChart.resize();
        });
    }

 

双柱状图,显示2个柱状图,区别仅在于 “series ”中多了一串数据

  function echarts_2(data) {
        // 基于准备好的dom,初始化echarts实例
        var myChart = echarts.init(document.getElementById('echart2'));

        option = {

堆叠柱状图,同双柱状图的区别在于“series”中增加一个“stack”属性

            tooltip: {

堆叠柱状图若想查看总数,可在设置一栏进行数据的相加,这样既可进行总数的查看

    function echarts_2(data) {
        var result =[];  //总数
        var maxNum = 0;  //最大数值,为了界面好看的,可不设置
        for(var i = 0; i < data.titleList.length;i++) {
            var sumNum = data.oneList[i] + data.twoList[i]
            result.push(sumNum)
            maxNum = sumNum >= maxNum ? sumNum : maxNum;
        }

        // 基于准备好的dom,初始化echarts实例
        var myChart = echarts.init(document.getElementById('echart2'));

        option = {
            //  backgroundColor: '#00265f',
