【vue】vue中引入echarts的两种方式

1.安装echarts依赖

　　npm install echarts -S

2.创建图表

a:全局引入

main.js页面

import echarts from \'echarts\'

Vue.prototype.$echarts = echarts

Hello.vue页面

<div id="myChart" :style="{width: \'300px\', height: \'300px\'}"></div>

<script>
export default {
  name: \'FuncFormsBase\',
  data () {
    return {
      msg: \'Welcome to Your Vue.js App\'
    }
  },
  mounted () {
    this.drawLine();
  },
  methods: {
    drawLine () {
      var echarts = require(\'echarts\');
      var myChart = echarts.init(document.getElementById(\'main\'));
      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]
        }]
      });
    }
  }
}
</script>

<style scoped>
</style>

　　

b: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。

// 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]
        }]
      });
    }
  }
}
