本文主要包含vue2-highcharts,数据,曲线等相关知识,匿名希望在学习及工作中可以帮助到您
这次给大家带来使用vue2-highcharts实现曲线数据，使用vue2-highcharts实现曲线数据的注意事项有哪些，下面就是实战案例，一起来看一下。
1、要实现的效果如下图：
2、vue前端页面如下：
<template>
<p>
<p>
<p>
<img src="../assets/index/back.png" class="rank-head-back" @click="routerBack"/>
<span >历史曲线</span>
</p>
</p>
<p >
<p >
<span >{{$route.params.monitorName}}({{$route.params.meterId}})</span>
</p>
</p>
<p >
<p >
<yesterdaypicker v-on:startPicked="startPicked" style="margin-left:10px;"></yesterdaypicker>
</p>
<p >
<daypicker v-on:endPicked="endPicked" style="margin-left:10px;"></daypicker>
</p>
</p>
<p >
<p >
<vchooser :selections="periodList" @on-change="onParamChange('versions', $event)"></vchooser>
</p>
</p>
<p >
<p class="charts" >
<vue-highcharts :options="options" ref="lineCharts" ></vue-highcharts>
</p>
</p>
</p>
</template>
