1.下载eachers

npm  i  eachrs

2.导入eachers

import * as echarts from "echarts";

3.布局

 

4.获取接口的数据

 getData().then(({ data }) => {
      const { tableData } = data.data;
      console.log(data);
      this.tableData = tableData;
      const echarts1 = echarts.init(this.$refs.echarts1);
      //  指定图表的配置项和数据
      var echarts1Option = {};
      //  处理数据
      const { orderData, userData, videoData } = data.data;
      const xAxis = Object.keys(orderData.data[0]);
      const xAxisData = {
        data: xAxis,
      };
      echarts1Option.yAxis = {};
      echarts1Option.xAxis = xAxisData;
      // 图例
      echarts1Option.legend = xAxisData;
      // series数量
      echarts1Option.series = [];
      xAxis.forEach((key) => {
        echarts1Option.series.push({
          name: key,
          data: orderData.data.map((item) => item[key]),
          type: "line",
        });
      });
      // 使用指定的配置项和数据显示图表
      echarts1.setOption(echarts1Option);

      // 柱状图
      // 初始化
      const echarts2 = echarts.init(this.$refs.echarts2);
      //  指定图表的配置项和数据
      var echarts2Option = {
        legend: {
          // 图例文字颜色
          textStyle: {
            color: "#333",
          },
        },
        grid: {
          left: "20%",
        },
        // 提示框
        tooltip: {
          trigger: "axis",
        },
        xAxis: {
          type: "category",
          data: userData.map((item) => item.data),
          axisLine: {
            lineStyle: {
              color: "#17b3a3",
            },
          },
          axisLabel: {
            interval: 0,
            color: "333",
          },
        },
        yAxis: [
          {
            type: "value",
            axisLine: {
              lineStyle: {
                color: "#17b3a3",
              },
            },
          },
        ],
        color: ["#2ec7c9", "#b6a2de"],
        series: [
          {
            name: "新增用户",
            data: userData.map((item) => item.new),
            type: "bar",
          },
          {
            name: "活跃用户",
            data: userData.map((item) => item.active),
            type: "bar",
          },
        ],
      };
      echarts2.setOption(echarts2Option);
      // 饼状图
      // const echarts3 = echarts.init(this.$refs.echarts3);
      const echarts3 = echarts.init(this.$refs.echarts3);
      var echarts3Option = {
        tooltip: {
          trigger: "item",
        },
        color: ["#0f78f4", "#dd536b", "#9462e5", "#a6a6a5", "#e1bb22"],
        series: [
          {
            data: videoData,
            type: "pie",
          },
        ],
      };
      // echarts3.setOption(echarts3Option)
      echarts3.setOption(echarts3Option);
    });

5.总结

1.获取盒子的大小做初始化

      const echarts1 = echarts.init(this.$refs.echarts1);

2.指定图表的配置项和数据

  var echarts1Option = {};

3.处理数据

 const { orderData, userData, videoData } = data.data;
      const xAxis = Object.keys(orderData.data[0]);
      const xAxisData = {
        data: xAxis,
      };
      echarts1Option.yAxis = {};
      echarts1Option.xAxis = xAxisData;
      // 图例
      echarts1Option.legend = xAxisData;
      // series数量
      echarts1Option.series = [];
      xAxis.forEach((key) => {
        echarts1Option.series.push({
          name: key,
          data: orderData.data.map((item) => item[key]),
          type: "line",
        });
      });

4.使用指定的配置项和数据显示图表

     echarts1.setOption(echarts1Option);
