這篇文章主要為大家詳細(xì)介紹了vue+echart實現(xiàn)雙柱狀圖，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了vue+echart實現(xiàn)雙柱狀圖的具體代碼，供大家參考，具體內(nèi)容如下

效果圖：

一、安裝

版本號建議安裝"echarts": "^4.8.0”，其它版本init會報錯

1、首先需要安裝echarts依賴包

npm install --save echarts@4.8.0

2、或者使用國內(nèi)的淘寶鏡像：

npm install -g cnpm --registry=https://registry.npm.taobao.org
