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,
},
