页面首次加载出来：

初始化时data的数据

const data = {
  nodes: [
    {
      id: "node1",
      x: 700,
      y: 100,
      size: [60, 100],
      label: "node1\n换行21",
      anchorPoints: [
        [0.5, 1],
        [0, 0.5]
      ]
    },
    {
      id: "node2",
      x: 700,
      y: 200,
      label: "222",
      anchorPoints: [
        [0.5, 1],
        [0.5, 1]
      ]
    },
  ],
  // 边集
  edges: [
    {
      source: "node1",//源头
      target: "node2",//目标
      type: "line",
      sourceAnchor: 0,
      // 该边连入 target 点的第 0 个 anchorPoint，
      targetAnchor: 0
    },
  ]
};
export default data

webscoket 推送过来的数据在页面打印出来了 antv G6绘制的图，
在

kline(msg) {
   console.log('msg', msg)
   this.msg = msg
},

拿到了数据 如何实时更新，第一次使用antv G6 哪位熟练的大佬指点下 谢谢
