一、安装并全局引入
1、通过npm获取echarts
npm install echarts --save2、在 main.js 中添加下面两行代码
- 在main.js中引入 5.0以下版本
import echarts from 'echarts ' - 5.0以上版本用这个引入 import * as echarts from ‘echarts’
// 原导入方式 import echarts from 'echarts' // 原导入方式 => 现导入方式 import * as echarts from 'echarts' Vue.prototype.$echarts = echarts;
二，组件中使用echarts
1，引入echarts
// 第一步引入echarts
// const echarts = require('echarts');
import * as echarts from 'echarts'2，挂在div视图区
<!-- 2.第二步 为ECharts准备一个具备大小（宽高）的Dom -->
<div id="main" style="width: 850px;height:400px;"></div>3，基于准备好dom，初始化echarts实例
// 第三步 3. 基于准备好的dom，初始化echarts实例
var myChart = echarts.init(document.getElementById('main'))4，准备数据和配置项
// 4.准备数据和配置项
myChart.setOption({
})
let option = {
title: {
text: '移动媒体曝光率'
},
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'cross',
label: {
backgroundColor: '#6a7985'
}
}
},
legend: {
data: ['邮箱', '手机', '平台', '广告', '微博']
},
toolbox: {
feature: {
saveAsImage: {}
}
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis: [
{
type: 'category',
boundaryGap: false,
data: ['星期一', '星期二', '星期三', '星期四', '星期五', '星期六', '星期天']
}
],
yAxis: [
{
type: 'value'
}
],
series: [
{
name: '邮箱',
type: 'line',
stack: 'Total',
areaStyle: {},
emphasis: {
focus: 'series'
},
data: [120, 132, 101, 134, 90, 230, 210]
},
{
name: '手机',
type: 'line',
stack: 'Total',
areaStyle: {},
emphasis: {
focus: 'series'
},
data: [220, 182, 191, 234, 290, 330, 310]
},
{
name: '平台',
type: 'line',
stack: 'Total',
areaStyle: {},
emphasis: {
focus: 'series'
},
data: [150, 232, 201, 154, 190, 330, 410]
},
{
name: '广告',
type: 'line',
stack: 'Total',
areaStyle: {},
emphasis: {
focus: 'series'
},
data: [320, 332, 301, 334, 390, 330, 320]
},
{
name: '微博',
type: 'line',
stack: 'Total',
label: {
show: true,
position: 'top'
},
areaStyle: {},
emphasis: {
focus: 'series'
},
data: [820, 932, 901, 934, 1290, 1330, 1320]
}
]
};5，调用-展示数据
