Vue项目引入echarts

参考链接：https://blog.csdn.net/guozhangqiang/article/details/82379306

1  首先进行全局安装：

npm install echarts -S  (权限不够可以加上sudo）

2  引入,一般使用表格都是多个图，你可以新建一个目录，我这里建目录charts保存图表组件

新建Chart.vue：

<template>
  <div :id="id" :class="className" :style="{height:height,width:width}" />
       // 定义了模板
</template>

<script>
import echarts from 'echarts'

export default {
  props: {
    className: {
      type: String,
      default: 'chart'  //模板名称
    },
    id: {
      type: String,
      default: 'chart'
    },
    width: {
      type: String,
      default: '200px'
    },
    height: {
      type: String,
      default: '200px'
    }
  },
  data() {
    return {
      chart: null
    }
  },
  mounted() {
    this.initChart()
  },
  beforeDestroy() {
    if (!this.chart) {
      return
    }
    this.chart.dispose()
    this.chart = null
  },
  methods: {
    initChart() {
      this.chart = echarts.init(document.getElementById(this.id))

      const xAxisData = []
      const data = []
      const data2 = []
      for (let i = 0; i < 50; i++) {
        xAxisData.push(i)
        data.push((Math.sin(i / 5) * (i / 5 - 10) + i / 6) * 5)
        data2.push((Math.sin(i / 5) * (i / 5 + 10) + i / 6) * 3)
      }
      this.chart.setOption({
        backgroundColor: '#08263a',
        grid: {
          left: '5%',
          right: '5%'
        },
        xAxis: [{
          show: false,
          data: xAxisData
        }, {
          show: false,
          data: xAxisData
        }],
        visualMap: {
          show: false,
          min: 0,
          max: 50,
          dimension: 0,
          inRange: {
            color: ['#4a657a', '#308e92', '#b1cfa5', '#f5d69f', '#f5898b', '#ef5055']
          }
        },
        yAxis: {
          axisLine: {
            show: false
          },
          axisLabel: {
            textStyle: {
              color: '#4a657a'
            }
          },
          splitLine: {
            show: true,
            lineStyle: {
              color: '#08263f'
            }
          },
          axisTick: {
            show: false
          }
        },
        series: [{
          name: 'back',
          type: 'bar',
          data: data2,
          z: 1,
          itemStyle: {
            normal: {
              opacity: 0.4,
              barBorderRadius: 5,
              shadowBlur: 3,
              shadowColor: '#111'
            }
          }
        }, {
          name: 'Simulate Shadow',
          type: 'line',
          data,
          z: 2,
          showSymbol: false,
          animationDelay: 0,
          animationEasing: 'linear',
          animationDuration: 1200,
          lineStyle: {
            normal: {
              color: 'transparent'
            }
          },
          areaStyle: {
            normal: {
              color: '#08263a',
              shadowBlur: 50,
              shadowColor: '#000'
            }
          }
        }, {
          name: 'front',
          type: 'bar',
          data,
          xAxisIndex: 1,
          z: 3,
          itemStyle: {
            normal: {
              barBorderRadius: 5
            }
          }
        }],
        animationEasing: 'elasticOut',
        animationEasingUpdate: 'elasticOut',
        animationDelay(idx) {
          return idx * 20
        },
        animationDelayUpdate(idx) {
          return idx * 20
        }
      })
    }
  }
}
</script>

建好组件之后，我在HelloWorld.vue中引用：

<template>
  <div class="chart-container">
    <chart height="100%" width="100%" />   //组件实例化,可以根据之前定义的给定样式参数
  </div>
</template>

<script>
import Chart from './charts/Chart'  //导入组件

export default {
  name: 'HelloWorld',
  components: { Chart }      //使用组件
}
</script>

<style scoped>
.chart-container{
  position: relative;
  width: 100%;
  height: calc(100vh - 84px);
}
</style>

效果：

还有可以直接定义一个图表组件Test.vue

<style scoped>
  h2{
    text-align: center;
    padding: 30px;
    font-size: 18px;
  }
  #chart_example{
    width: 50%;
    height: 500px;
    border: 1px solid red;
    margin: 0 auto;
  }
</style>
<template>
  <div>
    <h2>vue中插入Echarts示例</h2>
    <div id="chart_example">
 
    </div>
  </div>
</template>
 
<script>
  import echarts from 'echarts'
  export default {
    name:'Test',
    data() {
      return {}
    },
    mounted() {
      let this_ = this;
      let myChart = echarts.init(document.getElementById('chart_example'));
      let option = {
        color: ['#f44'],
        tooltip : {
          trigger: 'axis',
          axisPointer : {
            type : 'shadow'
          }
        },
        xAxis : [
          {
            type : 'category',
            data : ['1月','2月','3月','4月','5月','6月','7月','8月','9月','10月','11月','12月',],
            axisTick: {
              alignWithLabel: true
            }
          }
        ],
        yAxis : [
          {
            type : 'value'
          }
        ],
        series : [
          {
            name:'每月花费',
            type:'bar',
            barWidth: '60%',
            data:[995,666,444,858,654,236,645,546,846,225,547,356]
          }
        ]
      };
      myChart.setOption(option);
 
      //建议加上以下这一行代码，不加的效果图如下（当浏览器窗口缩小的时候）。超过了div的界限（红色边框）
      window.addEventListener('resize',function() {myChart.resize()});
    },
    methods: {},
    watch: {},
    created() {
 
    }
  }
</script>

然后在路由 router/index.js中定义：

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Test from '@/components/Test'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      component: HelloWorld
    },
    {
      path: '/test',
      name: 'Test',
      component: Test
    }
  ]
})

最后跑下代码打开test  url便可以看到效果：
