在內網中 vue項目添加ECharts圖表插件

原文地址:https://www.cnblogs.com/aknife/p/11753854.html

最近項目中要使用到圖表

但是項目在內網中無法直接使用命令安裝

然後我在外網中弄個vue的項目(隨便什麼項目)

先使用npm install echarts --save安裝

然後在項目node_modules下會出現這兩個文件

解壓拿到內網項目中,放到相同位置

然後在main.js中加2行代碼

 import echarts from 'echarts'

Vue.prototype.$echarts = echarts 

接著在package.json中加  "echarts": "^4.4.0", 

 接著創建一個.vue文件試試,直接粘貼以下代碼即可

<template>
  <div id="pieReport"
       style="width: 400px;height: 300px;"></div>
</template>
<script>
export default {
  name: "",
  data () {
    return {
      charts: "",
      opinion: ["及格人數", "未及格人數"],
      opinionData: [
        { value: 12, name: "及格人數", itemStyle: "#1ab394" },
        { value: 18, name: "未及格人數", itemStyle: "#79d2c0" }
      ]
    };
  }, mounted () {
    this.$nextTick(function () {
      this.drawPie("pieReport");
    });
  }, methods: {
    drawPie (id) {
      this.charts = this.$echarts.init(document.getElementById(id));
      this.charts.setOption({
        tooltip: {
          trigger: "item",
          formatter: "{a}<br/>{b}:{c} ({d}%)"
        },
        legend: {
          bottom: 10,
          left: "center",
          data: this.opinion
        },
        series: [
          {
            name: "狀態",
            type: "pie",
            radius: "65%",
            center: ["50%", "50%"],
            avoidLabelOverlap: false,
            itemStyle: {
              emphasis: {
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: "rgba(0, 0, 0, 0.5)"
              },
              color: function (params) {
                //自定義顏色
                var colorList = ["#1ab394", "#79d2c0"];
                return colorList[params.dataIndex];
              }
            },
            data: this.opinionData
          }
        ]
      });
    },

  }
}
</script>

完美!!
