Echarts橫向堆疊柱狀圖和markLine實例詳解
1.Echarts 橫向堆疊柱狀圖 + markLine
效果圖
根據月份計算百分比展示markLine
思路： 根據月份計算百分比展示markLine，例如3月就是25%，這裡的圖表是數值，所以markLine要展示百分比需要進行一下計算，思路是在series裡添加一個專門為瞭markLine處理的（這裡是雙柱子所以要采用這種方法，如果是單個柱子就不需要，可以直接在series裡邊項寫markLine），具體計算方式在option代碼上面，大傢自行看一下這裡不復制重復寫瞭
驗證：我這裡的x軸隱藏掉瞭，大傢為瞭驗證計算的對不對可以把axisLabel show: 改為true,對比下數值和markLine值是否正確
代碼如下：
mychart() {
var myChart = echarts.init(document.getElementById('profitTotal6'));
let echartData = [{
name: "其他",
value1: 64,
value2: 84,
},
{

2.Echarts 橫向堆疊柱狀圖 + markLine
效果圖
根據數據計算百分比展示markLine
代碼如下
根據數據計算百分比展示markLine，和上面基本同理，這個隻是數值上的轉換，和月份沒有關系瞭
