问题描述:
解决方案:
导入echarts时用:import echarts from ‘echarts’ 出现 “Cannot read property ‘init’ of undefined” 报错,改成 import * as echarts from ‘echarts’ 后解决。
避免出现上述问题解决方案:
第一步:
npm install echarts -S
第二步:
// 引入echarts
import echarts from 'echarts' Vue.prototype.$echarts = echarts
第三步:
// 引入基本模板
let echarts = require('echarts/lib/echarts')
// 引入柱状图组件
require('echarts/lib/chart/bar')
// 引入提示框和title组件
require('echarts/lib/component/tooltip')
require('echarts/lib/component/title')
export default {
name: 'hello',
data() {
return {
msg: 'Welcome to Your Vue.js App'
}
},
mounted() {
this.drawLine();
},
methods: {
drawLine() {
// 基于准备好的dom,初始化echarts实例
let myChart = echarts.init(document.getElementById('myChart'))
// 绘制图表
myChart.setOption({
title: { text: 'ECharts 入门示例' },
tooltip: {},
xAxis: {
data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
},
yAxis: {},
series: [{
name: '销量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}]
});
}
}
}
