Vue使用echarts

npm获取echarts

npm install echarts --save

main.js文件下引入echarts，新版本引入方式与以往不同

import * as echarts from 'echarts'

Vue.prototype.$echarts=echarts

创建vue文件，准备dom ,定义id名称，样式大小

<template>
	<div id="chart" style="width: 100%;height: 400px;"></div>
</template>

基于准备好的dom，初始化echarts实例

// 基于准备好的dom，初始化echarts实例
var myChart = this.$echarts.init(document.getElementById('chart'));

绘制图表 ，在echarts官网选择需要的图表，复制option

var option = {
				  title: {
				    text: 'SC'
				  },
				  tooltip: {
				    trigger: 'axis'
				  },
				  legend: {
				    data: ['game1', 'game2', 'game3', 'game4', 'game5']
				  },
				  grid: {
				    left: '3%',
				    right: '4%',
				    bottom: '3%',
				    containLabel: true
				  },
				  toolbox: {
				    feature: {
				      saveAsImage: {}
				    }
				  },
				  xAxis: {
				    type: 'category',
				    boundaryGap: false,
				    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
				  },
				  yAxis: {
				    type: 'value'
				  },
				  series: [
				    {
				      name: 'game1',
				      type: 'line',
				      stack: 'Total',
				      data: [120, 132, 101, 134, 90, 230, 210]
				    },
				    {
				      name: 'game2',
				      type: 'line',
				      stack: 'Total',
				      data: [220, 182, 191, 234, 290, 330, 310]
				    },
				    {
				      name: 'game3',
				      type: 'line',
				      stack: 'Total',
				      data: [150, 232, 201, 154, 190, 330, 410]
				    },
				    {
				      name: 'game4',
				      type: 'line',
				      stack: 'Total',
				      data: [320, 332, 301, 334, 390, 330, 320]
				    },
				    {
				      name: 'game5',
				      type: 'line',
				      stack: 'Total',
				      data: [820, 932, 901, 934, 1290, 1330, 1320]
				    }
				  ]
				}

绘制图表 

myChart.setOption(option);

钩子函数 mounted() 调用图表所在的方法，在页面挂载之前会被调用

mounted() {
			this.chart();
		}

全部代码，如下

<template>
	<div id="chart" style="width: 100%;height: 400px;"></div>
</template>

<script>
	export default{
		name:'historyChart',
		data(){
			return{
				
			}
		},
		methods:{
			 chart(){
				var myChart = this.$echarts.init(document.getElementById('chart'));
				var option = {
				  title: {
				    text: 'SC'
				  },
				  tooltip: {
				    trigger: 'axis'
				  },
				  legend: {
				    data: ['game1', 'game2', 'game3', 'game4', 'game5']
				  },
				  grid: {
				    left: '3%',
				    right: '4%',
				    bottom: '3%',
				    containLabel: true
				  },
				  toolbox: {
				    feature: {
				      saveAsImage: {}
				    }
				  },
				  xAxis: {
				    type: 'category',
				    boundaryGap: false,
				    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
				  },
				  yAxis: {
				    type: 'value'
				  },
				  series: [
				    {
				      name: 'game1',
				      type: 'line',
				      stack: 'Total',
				      data: [120, 132, 101, 134, 90, 230, 210]
				    },
				    {
				      name: 'game2',
				      type: 'line',
				      stack: 'Total',
				      data: [220, 182, 191, 234, 290, 330, 310]
				    },
				    {
				      name: 'game3',
				      type: 'line',
				      stack: 'Total',
				      data: [150, 232, 201, 154, 190, 330, 410]
				    },
				    {
				      name: 'game4',
				      type: 'line',
				      stack: 'Total',
				      data: [320, 332, 301, 334, 390, 330, 320]
				    },
				    {
				      name: 'game5',
				      type: 'line',
				      stack: 'Total',
				      data: [820, 932, 901, 934, 1290, 1330, 1320]
				    }
				  ]
				}
				myChart.setOption(option);
			}
		},
		mounted() {
			this.chart();
		}
	} 
</script>
