数据量5w的热力图，直接渲染不出来，移除图例也渲染不出来 #5050

官方demo可以跑，实际业务中的数据量达到5w的热力图就渲染不上，已经去除图例

chart.options({
  type: "view",
  theme: "classic",
  width: 1152,
  height: 780,
  paddingLeft: 60,
  data: vData,
  sort: false,
  legend: false, // 关闭图例
  forceSquare: true,
  scale: {
    color: {
      palette: "turbo",
    },
  },
  axis: {
    y: { labelAutoHide: true, labelAutoRotate: false },
    x: { labelAutoHide: true, labelAutoRotate: false },
  },
  children: [
    {
      type: "cell",
      encode: { x: 'x', y: 'y', color: "z" },
    },
  ],
});
