网格热力通过.source设置网格大小不生效

问题描述

  this.heatmapLayer.source(this.d, {
    parser: {
      type: "json",
      x: "lng",
      y: "lat",
    },
    transforms: [
      {
        type: "grid",
        size: this.value1,
        field: "v",
        method: "sum",
      },
    ],
  });
  this.polygonLayer.size("sum", [0, this.value1 * 4]);
  this.scene.render();

}
通过.source设置网格大小失效，试了通过.size设置网格高度是生效的，请问怎么设置网格的大小

网格大小通过 transform 实现，可以看下面的demo

直接设置网格大小是可以的，但是想实现动态设置网格大小的功能，通过.source将transforms中的size设置为value1不生效
handleChange() {
this.polygonLayer.source(this.d, {
parser: {
type: "json",
x: "lng",
y: "lat",
},
transforms: [
{
type: "grid",
size: this.value1,
field: "v",
method: "sum",
},
],
});
this.polygonLayer.size("sum", [0, this.value1 * 4]);
this.scene.render();
}

更新网格大小需要通过 setData 更新
