圖表

補(bǔ)充知識(shí)：vue+echart實(shí)現(xiàn) X軸 雙柱狀圖 漸變色

一: 安裝

1. 首先需要安裝echarts依賴包

npm install echarts -S

2. 或者使用國(guó)內(nèi)的淘寶鏡像：

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

二: 創(chuàng)建圖表

全局引入

main.js

>```javascript// 引入echartsimport echarts from ’echarts’Vue.prototype.$echarts = echarts
