這篇文章主要介紹“Echarts橫向堆疊柱狀圖和markLine怎么使用”，在日常操作中，相信很多人在Echarts橫向堆疊柱狀圖和markLine怎么使用問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”Echarts橫向堆疊柱狀圖和markLine怎么使用”的疑惑有所幫助！接下來，請跟著小編一起來學(xué)習(xí)吧！
根據(jù)月份計算百分比展示markLine
思路： 根據(jù)月份計算百分比展示markLine，例如3月就是25%，這里的圖表是數(shù)值，所以markLine要展示百分比需要進行一下計算，思路是在series里添加一個專門為了markLine處理的（這里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里邊項寫markLine），具體計算方式在option代碼上面，大家自行看一下這里不復(fù)制重復(fù)寫了
驗證：我這里的x軸隱藏掉了，大家為了驗證計算的對不對可以把axisLabel show: 改為true,對比下數(shù)值和markLine值是否正確
