Vue echarts

方式1、直接引入echarts

先 npm 安裝 echarts

npm install echarts --save

// main.js
import myCharts from './comm/js/myCharts.js'
Vue.use(myCharts)

// myCharts.js
/**
 * 各類畫echarts圖表的方法都封裝在這裏
 * 注意：這裏echarts沒有采用按需引入的方式，只是爲了方便學習
 */

import echarts from 'echarts'
const install = function(Vue) {
    Object.defineProperties(Vue.prototype, {
        $chart: {
            get() {
                return {
                    //畫一條簡單的線
                    line1: function (id) {
                        this.chart = echarts.init(document.getElementById(id));
                        this.chart.clear();

                        const optionData = {
                            xAxis: {
                                type: 'category',
                                data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
                            },
                            yAxis: {
                                type: 'value'
                            },
                            series: [{
                                data: [820, 932, 901, 934, 1290, 1330, 1320],
                                type: 'line',
                                smooth: true
                            }]
                        };

                        this.chart.setOption(optionData);
                    },
                }
            }
        }
    })
}

export default {
    install
}

// helloWorld.vue
<template>
  <div class="hello">
    <div id="chart1"></div>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
    }
  },
  mounted() {
    this.$chart.line1('chart1');
  }
}
</script>

<style scoped>
  #chart1 {
    width: 300px;
    height: 300px;
  }
</style>

方式2、使用vue-echarts

先 npm 安裝 vue-echarts

npm install vue-echarts --save

除了全量引用echarts，咱們還能夠採用按需引入的方式

// main.js
import ECharts from 'vue-echarts/components/ECharts'
import 'echarts/lib/chart/line'
Vue.component('chart', ECharts)

// helloWorld.vue
<template>
  <div class="hello">
    <chart ref="chart1" :options="orgOptions" :auto-resize="true"></chart>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data () {
    return {
      orgOptions: {},
    }
  },
  mounted() {
    this.orgOptions = {
        xAxis: {
            type: 'category',
            data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
        },
        yAxis: {
            type: 'value'
        },
        series: [{
            data: [820, 932, 901, 934, 1290, 1330, 1320],
            type: 'line',
            smooth: true
        }]
    }
  }
}
    </script>

注意： 圖表自適應 :auto-resize="true" 偶爾不起做用，能夠試試 添加屬性 autoresize，如

<template>
  <div class="hello">
    <chart 
        ref="chart1" 
        :options="orgOptions" 
        autoresize>
    </chart>
  </div>
</template>
