echarts3.0的tree形图添加roam:true是否无效

Question

我给tree加上roam:true无效，但是在关系图中有效，是不是echarts3.0的tree不支持这个参数啊

let myChart = this.$echarts.init(document.getElementById("myChart"));
      myChart.setOption({
        tooltip: {
          trigger: "item",
          triggerOn: "mousemove"
        },
        series: [
          {
            type: "tree",
            name: "tree2",
            roam: true,
            data: [
              {
                name: "flare",
                children: [
                  {
                    name: "flex",
                    children: [{ name: "FlareVis", value: 4116 }]
                  },
                  {
                    name: "scale",
                    children: [
                      { name: "IScaleMap", value: 2105 },
                      { name: "LinearScale", value: 1316 },
                      { name: "LogScale", value: 3151 },
                      { name: "OrdinalScale", value: 3770 },

                    ]
                  },
                  {
                    name: "display",
                    children: [{ name: "DirtySprite", value: 8833 }]
                  }
                ]
              }
            ],
            symbolSize: 7,

            label: {
              normal: {
                position: "left",
                verticalAlign: "middle",
                align: "right"
              }
            },

            leaves: {
              label: {
                normal: {
                  position: "right",
                  verticalAlign: "middle",
                  align: "left"
                }
              }
            },

            expandAndCollapse: true,

            animationDuration: 550,
            animationDurationUpdate: 750
          }
        ]
      });

你好 请问这个问题解决了吗？ 我自己本地试验也是无效，但是官方的demo里面进行添加就可以正常缩放和平移 我用的是echart4.1版本
