1、安装
npm install echarts --save
2、在vue中引入（全局引入）
// 引入echarts
import echarts from 'echarts'
Vue.prototype.$echarts = echarts
3、在vue中的使用
需要用到echart的地方先设置一个div的id、宽高
提示：
可以在一个页面中引入多个数据报表模板
使用div进行位置的排版放置
4、模板代码放在哪个位置
重点注意：其中const option = { }就是我们需要引进echart图表的代码
<template>
<div>
<div ref="chart" style="width:50%;height:376px"></div>
</div>
</template>
要在mounted生命周期函数中实例化echarts对象。确保dom元素已经挂载到页面中。
mounted(){
this.getEchartData()
},
methods: {
getEchartData() {
const chart = this.$refs.chart
if (chart) {
const myChart = this.$echarts.init(chart)
const option = {...}
myChart.setOption(option)
window.addEventListener("resize", function() {
myChart.resize()
})
}
this.$on('hook:destroyed',()=>{
window.removeEventListener("resize", function() {
myChart.resize();
});
})
}
}
5、完整的一个vue页面实例：
<template>
<div>
<div ref="chart" style="width:50%;height:376px"></div>
<div ref="chart1" style="width:50%;height:376px"></div>
</div>
</template>
<script>
export default {
data() {
},
mounted() {
this.getEchartData()
this.getEchartData1()
},
methods: {
getEchartData() {
const chart = this.$refs.chart
if (chart) {
const myChart = this.$echarts.init(chart)
const option = { legend: {},
tooltip: {},
dataset: {
source: [
['订单', 43.3, 85.8],
['订单1', 83.1, 73.4],
['订单2', 86.4, 65.2],
['订单3', 72.4, 53.9],
['订单4', 82.4, 53.9],
['订单5', 42.4, 53.9],
['订单6', 72.4, 53.9],
['订单7', 72.4, 53.9]
]
},
xAxis: { type: 'category' },
yAxis: {},
series: [ { type: 'bar' }, { type: 'bar' }]}
myChart.setOption(option)
window.addEventListener("resize", function() {
myChart.resize()
})
}
this.$on('hook:destroyed',()=>{
window.removeEventListener("resize", function() {
myChart.resize();
});
})
},
getEchartData1() {
const chart1 = this.$refs.chart1
if (chart1) {
const myChart = this.$echarts.init(chart1)
const option = {
title: {
text: 'Stacked Line'
},
tooltip: {
trigger: 'axis'
},
legend: {
data: ['Email', 'Union Ads', 'Video Ads', 'Direct', 'Search Engine']
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
toolbox: {
feature: {
saveAsImage: {}
}
},
xAxis: {
type: 'category',
boundaryGap: false,
data: ['一月', '二月', '三月', '四月', '五月', '六月', '七月','八月','九月','十月','十一月','十二月']
},
yAxis: {
type: 'value'
},
series: [
{
name: 'Email',
type: 'line',
stack: 'Total',
data: [120, 132, 101, 134, 90, 230, 210,120, 132, 101, 134, 90, 230]
},
{
name: 'Union Ads',
type: 'line',
stack: 'Total',
data: [220, 182, 191, 234, 290, 330, 310,220, 182, 191, 234, 290, 330]
},
{
name: 'Video Ads',
type: 'line',
stack: 'Total',
data: [150, 232, 201, 154, 190, 330, 410,150, 232, 201, 154, 190, 330]
},
{
name: 'Direct',
type: 'line',
stack: 'Total',
data: [320, 332, 301, 334, 390, 330, 320,320, 332, 301, 334, 390, 330]
},
{
name: 'Search Engine',
type: 'line',
stack: 'Total',
data: [820, 932, 901, 934, 1290, 1330, 1320,820, 932, 901, 934, 1290, 1330]
}
]
}
myChart.setOption(option)
window.addEventListener("resize", function() {
myChart.resize()
})
}
this.$on('hook:destroyed',()=>{
window.removeEventListener("resize", function() {
myChart.resize();
});
})
},
},
watch: {},
created() {
}
}
</script>
6、实现效果
7、可能遇到的问题，下载不成功。使用
cnpm install echarts --save
8、11:25-32 "export ‘default’ (imported as ‘echarts’) was not found in 'echarts
修改引入的方式
// 引入echarts
import *as echarts from 'echarts'
Vue.prototype.$echarts = echarts
