如何在vue中使用echarts

如何在vue中使用echarts

1. 下载安装

npm install echarts

若安装失败则改为:cnpm install echarts

2. 在vue中引入echarts(全局配置main.js)

/* 导入echarts组件 */
import echarts from 'echarts'
Vue.use(echarts);

3. 在vue中使用echarts

我的测试:

<template>
  <div>
    <div class="container">
        <div id="echart">div>
    div>
  div>
template>
<script>
import * as echarts from 'echarts';
export default {
	
  data() {
    return {};
  },
  // 页面初始化挂载dom
  mounted() {
    this.getLoadEcharts();
	
  },
  methods: {
    getLoadEcharts() {
      var myChart = this.$echarts.init(
        document.getElementById("echart")
      );
	  
	  //数据区域
	  
   // prettier-ignore
   let dataAxis = ['点', '击', '柱', '子', '或', '者', '两', '指', '在', '触', '屏', '上', '滑', '动', '能', '够', '自', '动', '缩', '放'];
   // prettier-ignore
   let data = [220, 182, 191, 234, 290, 330, 310, 123, 442, 321, 90, 149, 210, 122, 133, 334, 198, 123, 125, 220];
   let yMax = 500;
   let dataShadow = [];
   for (let i = 0; i < data.length; i++) {
     dataShadow.push(yMax);
   }
  var option = {
     title: {
       text: '特性示例：渐变色 阴影 点击缩放',
       subtext: 'Feature Sample: Gradient Color, Shadow, Click Zoom'
     },
     xAxis: {
       data: dataAxis,
       axisLabel: {
         inside: true,
         color: '#fff'
       },
       axisTick: {
         show: false
       },
       axisLine: {
         show: false
       },
       z: 10
     },
     yAxis: {
       axisLine: {
         show: false
       },
       axisTick: {
         show: false
       },
       axisLabel: {
         color: '#999'
       }
     },
     dataZoom: [
       {
         type: 'inside'
       }
     ],
     series: [
       {
         type: 'bar',
         showBackground: true,
         itemStyle: {
           color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
             { offset: 0, color: '#83bff6' },
             { offset: 0.5, color: '#188df0' },
             { offset: 1, color: '#188df0' }
           ])
         },
         emphasis: {
           itemStyle: {
             color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [
               { offset: 0, color: '#2378f7' },
               { offset: 0.7, color: '#2378f7' },
               { offset: 1, color: '#83bff6' }
             ])
           }
         },
         data: data
       }
     ]
   };
   
   // Enable data zoom when user click bar.
   const zoomSize = 6;
   myChart.on('click', function (params) {
     console.log(dataAxis[Math.max(params.dataIndex - zoomSize / 2, 0)]);
     myChart.dispatchAction({
       type: 'dataZoom',
       startValue: dataAxis[Math.max(params.dataIndex - zoomSize / 2, 0)],
       endValue:
         dataAxis[Math.min(params.dataIndex + zoomSize / 2, data.length - 1)]
     });
   });

      myChart.setOption(option);
    }
  }
};
script>
<style scoped>
.container{
   width: 900px;
    height: 600px;

    margin-left: 30px;
}
#echart{
    width: 100%;
    height: 100%;
}
style>

效果展示

可能遇到的问题:

如果在项目中的main.js中已经引入了echarts，却出现了该报错vue echarts is not defined,建议降低echarts版本(npm install [email protected] --save )或者在应用echarts图表的页面内引入import * as echarts from 'echarts';
