在内网中 vue项目添加ECharts图表插件

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

最近项目中要使用到图表

但是项目在内网中无法直接使用命令安装

 

然后我在外网中弄个vue的项目(随便什么项目)

先使用npm install echarts --save安装

然后在项目node_modules下会出现这两个文件

 

解压拿到内网项目中,放到相同位置

然后在main.js中加2行代码

 import echarts from 'echarts'

vue.prototype.$echarts = echarts 

 

 

接着在package.json中加  "echarts": "^4.4.0", 

 

 

 接着创建一个.vue文件试试,直接粘贴以下代码即可

<template>
  <div id="piereport"
       style="width: 400px;height: 300px;"></div>
</template>
<script>
export default {
  name: "",
  data () {
    return {
      charts: "",
      opinion: ["及格人数", "未及格人数"],
      opiniondata: [
        { value: 12, name: "及格人数", itemstyle: "#1ab394" },
        { value: 18, name: "未及格人数", 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: "状态",
            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) {
                //自定义颜色
                var colorlist = ["#1ab394", "#79d2c0"];
                return colorlist[params.dataindex];
              }
            },
            data: this.opiniondata
          }
        ]
      });
    },

  }
}
</script>

完美!!
