通过点击不同的按钮显示不同的图表

最后整体效果是这样的：

2.实现思路

(1)两个按钮进行切换

  <div class="callBtn">
        <el-row>
          <el-button @click="changeOutColor" :type="outColor"
            >呼出</el-button
          >
          <el-button @click="changeInColor" :type="inColor">呼入</el-button>
        </el-row>
      </div>

      

 data() {
    return {

      outColor: "danger",
      inColor: "",
    };
  },
methods:{
 changeOutColor() {
      if (this.outColor == "") {
        this.outColor = "danger";
        this.inColor = "";
      }
    },
    changeInColor() {
      if (this.inColor == "") {
        this.inColor = "danger";
        this.outColor = "";
      }
    },
}


//样式
  .el-button--danger:hover,
    .el-button--danger:focus {
      background: #ff6d6d;
      border-color: #ff6d6d;
      color: #ffffff;
    }

.el-button:hover,
.el-button:focus {
  color: black;
  border-color: #dcdfe6;
  background-color: #fff;
}

这样就可以两个按钮间相互切换了的，样式都可以根据自己的需求进行修改的

(2)将按钮和图表关联起来

这里我们选的是v-show指令实现

   <div class="callBtn">
        <el-row>
          <el-button @click="changeOutColor(1)" :type="outColor"
            >呼出</el-button
          >
          <el-button @click="changeInColor(2)" :type="inColor">呼入</el-button>
        </el-row>
      </div>


<div class="callChartAaea">
        <div
          id="callOutChart"
          v-show="showChart == 1"
          :style="{
            height: '400px',
            width: '400px',
            boxShadow:
              '0 2px 4px rgba(0, 0, 0, .12), 0 0 6px rgba(0, 0, 0, .04)',
          }"
        ></div>
        <div
          id="callInChart"
          v-show="showChart == 2"
          :style="{
            height: '400px',
            width: '400px',
            boxShadow:
              '0 2px 4px rgba(0, 0, 0, .12), 0 0 6px rgba(0, 0, 0, .04)',
          }"
        ></div>
      </div>


  mounted() {
    this.drawLine();
  },
  data() {
    return {
      outColor: "danger",
      inColor: "",
      showChart: 1,
    };
  },
  methods: {
    drawLine() {
      // 基于准备好的dom，初始化echarts实例
 
      let callOutChart = this.$echarts.init(
        document.getElementById("callOutChart")
      );
      let callInChart = this.$echarts.init(
        document.getElementById("callInChart")
      );
   
      // 绘制图表
      callOutChart.setOption({
        //标题
        title: {
          text: "测试案例",
          left: "left",
        },
