vue中实现echart图表
项目中涉及到柱状图 折线图 饼图 主要思路 页面级组件里引用三个图标子组件 在子组件中配置echart图标配置信息 在父组件中传入数据值
注意问题 ： 子组件id不能重复
父组件 主要代码
引入组件<el-row>
<el-col :span="24">
<div class="item-box">
<my-chart :chartData="chart0"></my-chart>
</div>
</el-col>
</el-row>
<el-row :gutter="20">
<el-col :span="8">
<div class="item-box">
<myCharta :chartData="chart1"></myCharta>
</div>
</el-col>
<el-col :span="8">
<div class="item-box">
<my-chartb :chartData="chart2"></my-chartb>
</div>
</el-col>
<el-col :span="8">
<div class="item-box">
<myChartc :chartData="chart3"></myChartc>
</div>
</el-col>
</el-row>
//导入组件
import MyChart from './dashboard/myChart'

import MyChartb from './dashboard/myChartb'
import MyChartc from './dashboard/myChartc'
//注册组件
