1.Echarts 横向堆叠柱状图 + markLine

效果图

根据月份计算百分比展示markLine

思路: 根据月份计算百分比展示markLine,例如3月就是25%,这里的图表是数值,所以markLine要展示百分比需要进行一下计算,思路是在series里添加一个专门为了markLine处理的(这里是双柱子所以要采用这种方法,如果是单个柱子就不需要,可以直接在series里边项写markLine),具体计算方式在option代码上面,大家自行看一下这里不复制重复写了

验证:我这里的x轴隐藏掉了,大家为了验证计算的对不对可以把axisLabel show: 改为true,对比下数值和markLine值是否正确

代码如下:

mychart() {
    var myChart = echarts.init(document.getElementById('profitTotal6'));
    let echartData = [{
        name: "其他",
        value1: 64,
        value2: 84,
    },

        name: "运输",
        value1: 104,
        value2: 164,
    },

        name: "化工",
        value1: 619.59,
        value2: 354.00,
    },
