Echarts横向堆叠柱状图和markLine实例详解
作者：vaelcy
一些柱形图在数据量比较多的时候,横向排列受到挤压,导致柱形图,变的非常细,影响整体的效果,所以应该将柱形图堆叠起来,这样就会好很多,下面这篇文章主要给大家介绍了关于Echarts横向堆叠柱状图和markLine的相关资料,需要的朋友可以参考下
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,
},
{

value2: 164,

let bgdata = [];
echartData.map(item => {
bgdata.push(parseInt(item.value1 + item.value2) + 100);
})
let maxxAxis = Math.max.apply(null,bgdata);//设置x轴最大值
let date_ = new Date();
let month = date_.getMonth() + 1;
let markyAxis = maxxAxis / 12 * month; //markLine值
let markyvalueText = parseInt(markyAxis / maxxAxis * 100); //为了控制百分样式
let paddingStyle;//根据数值动态设置padding样式
if (0 <= markyvalueText && markyvalueText < 10) {
paddingStyle = [10, 7];
