【highCharts绘制3d饼图】有、无高低差的3d饼图

在Vue中使用highCharts绘制3d饼图的方法

参考： 在Vue中使用highCharts绘制3d饼图的方法

首先使用 npm在你的项目中安装vue-highcharts

npm install vue-highcharts --save

由于vue-highcharts依赖于highcharts，我们还需要安装后者

npm install highcharts --save

或者

yarn add  highcharts --save
yarn  add  vue-highcharts --save

安装完成后，进入项目main.js进行配置：

import highcharts from 'highcharts'
import VueHighCharts from 'vue-highcharts'

引入以上两项之后，因为我们需要使用3d图表，还需要引入：

import highcharts3d from 'highcharts/highcharts-3d'

调用3d图表：

highcharts3d(highcharts)

OK，到此为止已经在vue中配置好highcharts,接下来根据API绘制一份3d饼图

无高低差的3d饼图

新建一个饼图的组件：

在需要使用饼图的页面里配置option数据

推荐用这个：有高低差的3d饼图（item.h设一样的、events里面注释掉，也能变成无高低差的3d饼图）

import { highchartsPie } from './hightChart.js'

      let pieData = []
      let total = 0
