安装echarts依赖
npm install echarts -S
创建图表
全局引入
- main.js
// 引入echarts import echarts from ‘echarts‘ Vue.prototype.$echarts = echarts
- Hello.vue
<div id="myChart" :style="{width: ‘300px‘, height: ‘300px‘}"></div>
export default { name: ‘hello‘, data () { return { msg: ‘Welcome to Your Vue.js App‘ } }, mounted(){ this.drawLine(); }, methods: { drawLine(){ // 基于准备好的dom,初始化echarts实例 let myChart = this.$echarts.init(document.getElementById(‘myChart‘)) // 绘制图表 myChart.setOption({ title: { text: ‘在Vue中使用echarts‘ }, 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] }] }); } } }
注意: 这里echarts初始化应在钩子函数mounted()中,这个钩子函数是在el 被新创建的 vm.$el 替换,并挂载到实例上去之后调用
按需引入
上面全局引入会将所有的echarts图表打包,导致体积过大,所以我觉得最好还是按需引入。
- Hello.vue
import echarts from ‘echarts/lib/echarts‘; // 引入柱状图 import ‘echarts/lib/chart/pie‘; // 引入提示框和title组件 import ‘echarts/lib/component/title‘; import ‘echarts/lib/component/legend‘;
