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: {
          width: "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:

              fontSize: 12
            }
          }
        },

          }
        },
        series: series//你的数据
      };               

　　

　　其中option.toolbox.feature.myTool2.icon是图标svg绘制路径，可以在iconfont中获取，方法如下：

　　（1）图标加入购物车，购物车中下载素材

　　（2）选择导出svg

（3）得到path路径
