npm进行highchars的导入,导入完成后就可以进行highchars的可视化组件开发了

npm install highcharts --save

1、components目录下新建一个chart.vue组件


<template>
 <div class="chart" id="myChart" >
 <div class="emcs_charts" :id="id" ></div>
 </div>
</template>
<script>
// 引入highCharts模块
import HighCharts from 'highcharts'
// 引入这个图表的外部资源数据
import data from '../echarts_data/chart.js'
export default {
 data() {
 // 将引入的数据写在自己的组件中
 let dataObj = data.bar
 return{
 id: 'chart',
 dataObj: dataObj
 }
 },
 mounted() {//钩子函数挂载时实例化这个图表
 // chart(参数1,参数2);第一个参数挂载组件的容器,第二个参数为图表所需要的数据对象
 HighCharts.chart(this.id,this.dataObj)
 }
}
</script>
<style scoped lang='stylus'>
.chart{
 float left ;
 background-color #fff;
 padding 10px 0;
 margin-top 20px;
 border-radius 6px
 width 49.5%;
 .emcs_charts{
 min-width 890px;
 height 280px;
 }
}
</style>

2、chart组件建好后,开始创建chart-options目录,里面创建一个chart.js用来存放模拟的chart数据

如下图我写的一个面积图的数据


module.exports = {
 bar: {
 chart: {//图表样式
 type:'area',//指定图表的类型,这里是面积图
 },
 //是否启用Labels。x,y轴默认值都是true,如果想禁用(或不显示)Labels,设置该属性为false即可
 credits: {
 enabled:false
 },
 title: {//指定图表标题
 text: ' 设备监控', 
 align: 'left',
 style:{
 color: '#666',
 fontSize:'16px',
 }
 },
 colors: ['rgba(86,199,99,1)','rgba(226,188,37,1)','rgba(255,133,133,1)'],
 xAxis: {//图表的横坐标,一个轴为{ }
 title:{//横坐标标题
 text:''
 },
 //x坐标轴的刻度值
 categories: ['4:40','4:41','4:42','4:43','4:44', '4:45', '4:46', '4:47', '4:48', '4:49', '4:50','4:51','4:52','4:53','4:54', '4:55', '4:56', '4:57', '4:58', '4:59', '5:00', '5:01', '5:02', '5:03', '5:04', '5:05', '5:06', '5:07', '5:08', '5:09', '5:10', '5:11', '5:12', '5:13', '5:14', '5:15', '5:16', '5:17', '5:18', '5:19', '5:20', '5:21', '5:22', '5:23', '5:24', '5:25', '5:26', '5:27', '5:28', '5:29', '5:30', '5:31', '5:32', '5:33', '5:34', '5:35', '5:36', '5:37', '5:38', '5:39', '5:40'], //指定x轴分组
 labels: {//坐标轴上的刻度值(显示间隔、样式、单位)
 style: {
 color: '#999999'
 },
 format:'{value}pm',//刻度值的单位
 align: 'center'
 },
 lineColor: '#dfdfdf',//坐标轴的颜色
 tickColor: '#dfdfdf',//坐标轴上的刻度线的颜色
 tickLength: 5,//坐标轴上刻度线的长度
 gridLineWidth:1,//网格线宽度。x轴默认为0,y轴默认为1px。
 gridLineColor:'#f2f2f2',//网格线颜色。默认为:#C0C0C0。
 // gridLineDashStyle: 'Dash',//网格线线条样式。和Css border-style类似,常用的有:Solid、Dot、Dash
 tickInterval: 5,//刻度间隔
 tickmarkPlacement: 'between',//刻度线对齐方式,有between和on可选,默认是between
 style: {
 color: '#999999',
 fontSize:10
 },
 crosshair:{//鼠标放上后显示纵轴的数据
 color:'#999',
 width:1
 }
 },
 yAxis: [{//图表的纵坐标,多个轴[{轴一},{轴二}]
 gridLineWidth: 1,
 gridLineColor:'#f2f2f2',
 tickPositions: [0, 25, 50, 75, 100],//y轴刻度值
 tickLength:0,
 title: {//纵坐标标题
 text: ' ',
 margin:0,
 style: {
 color: '#999999',
 fontSize:10
 }
 },
 labels:{//坐标轴上刻度的样式及单位
 style: {
 color: '#999999',
 fontSize:10
 },
 format:'{value}%',//坐标轴上的单位
 },
 offset:-10,//距离坐标轴的距离
 },{
 gridLineWidth: 1,
 gridLineColor:'#f2f2f2',
 tickColor: '#fff',
 tickInterval:25,
 tickLength:0,
 title: {
 text: '',
 margin:0,
 style: {

 fontSize:10
 }
 },
 labels:{
 style: {
 color: '#999999',
 fontSize:10
 },
 format:'{value}℃'
 },
 opposite:true,//设置opposite: true表示该轴位置反转,即为y轴时显示在右侧
 offset:-10
 }],
 tooltip: {//数据提示框
 headerFormat: '<small>{point.key}</small><br/>',//标题格式
 pointFormat: '<span style="color:{series.color};">{series.name}</span>:{point.y}<br/>',
 shared: true,
 followPointer:true,//跟随鼠标
 followPointerMove:true,//是否跟随手指移动
 // footerFormat: 'muzi',//尾部格式化字符串
 style:{
 fontSize:10,
 fontFamily:'微软雅黑',
 fontWeight:'normal',
 color:'#666'
 }
 },
 //标示线总是垂直于它属于的轴。它可单独定义在x轴或y轴,也可以同时定义在x轴和y轴
 plotOptions: {
 area: {
 //pointStart: 1940,
 marker: {
 enabled: false,
 symbol: 'circle',
 radius: 2,
 states: {
 hover: {
 enabled: true
 }
 }
 },
 fillOpacity:0.2,
 lineWidth:1
 }
 },
 legend: {//图例居中显示在图表下方
 align: 'center',
 symbolRadius:5,//图标圆角
 symbolWidth:10,//图标宽度
 symbolHeight:10,//图标高度
 itemStyle: {
 color: '#999999',
 fontWeight:'normal',
 fontSize:12
 },
 itemMarginBottom: -14,//图例项底部外边距
 },
 series: [{//数据列是一组数据集合
 name: 'CPU',//name 代表数据列的名字,并且会显示在数据提示框(Tooltip)及图例(Legend)中
 data: [
 5, 6, 10, 20, 50, 45, 30, 20, 10, 15,
 16, 17, 18, 18, 30, 26, 25, 24, 20, 26,
 36, 46, 50, 51, 52, 40, 30, 20, 19, 18,
 30, 50, 55, 56, 70, 72, 73, 60, 55, 54,
 53, 40, 39, 35, 32, 30, 20, 18, 3, 5,
 10, 12, 13, 23, 34, 56, 60, 70, 80, 90, 80
 ],
 tooltip: {
 valueSuffix:'%'
 }
 }, {
 name: 'RAM',
 data:[
 16, 17, 18, 18, 30, 26, 25, 24, 20, 26,
 36, 46, 50, 51, 52, 40, 30, 20, 19, 18,
 30, 50, 55, 56, 70, 72, 73, 60, 55, 54,
 53, 40, 39, 35, 32, 30, 20, 18, 3, 5,
 10, 12, 13, 23, 34, 56, 60, 70, 80, 90,
 5, 6, 10, 20, 50, 45, 30, 20, 10, 15, 20
 ],
 tooltip: {
 valueSuffix:'%'
 }
 }, {
 name: '温度',
 data:[
 10, 11, 11, 12, 12, 13, 14, 15, 16, 16,
 16, 16, 16, 16, 16, 16, 16, 16, 16, 16,
 16, 16, 16, 16, 16, 16, 16, 16, 16, 16,
 16, 16, 16, 16, 16, 16, 16, 16, 16, 16,
 16, 16, 16, 16, 16, 16, 16, 16, 16, 16,
 16, 16, 16, 16, 16, 16, 16, 16, 16, 16, 16
 ],
 tooltip: {
 valueSuffix:'℃'//值的前缀、后缀及小数点
 },
 yAxis:1
 }]
 }
 }

3、父组件引用chart.vue子组件


<template>
 <div class="charts" id="myChart" >
 <x-chart ></x-chart>
 </div>
</template>
<script>
// 导入chart.vue子组件
import XChart from './chart.vue'
export default {
 components: {
 XChart
 }
}
</script>
<style scoped lang='stylus'>
</style>

效果如下图所示

若有不足请多多指教!希望给您带来帮助!
