在vue项目中引入highcharts图表的方法

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: {
          color: '#999999',
          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
