echarts折线图上需要自定义工具按钮，实现如下：

var option = {
        title: {
          text: "pv"
        },
        tooltip: {
          trigger: "axis"
        },
        legend: {
           "60%",
          fontSize: 10,
          textStyle: {
            fontSize: 10
          },
          data: legend//你的数据
        },
        toolbox: {
          feature: {
            myTool2: {//自定义工具按钮只能以 my 开头
              show: true,
              title: "放大",
              iconStyle: {
                borderColor: "#39f"
              },　　    
              icon:

　　（2）选择导出svg

（3）得到path路径

最后上效果图：
