Handle incremental data loading keeps switching between two layers

[acebelowzero]

When I start my method to begin loading all the data I have two scenegraph layers in my layers but they keep replacing each other.

async *filterByDate() {
      let iter = 0;
      let offset = 0;
      ///this.loading = true;
      for (let it = 0; it < 10; it++) {
         const chunk = await axios
          .post("/api/DronesbyDate", {
            To: this.dateTo,
            From: this.dateFrom,
            offset: offset,
          });
          offset += 5000;
          yield chunk.data;
      }
    },

upd() {
            const layers = [
            new ScenegraphLayer({
              id: "scenegraph-layer",
              data: this.filterByDate(),
              pickable: true,
              scenegraph: MODEL_URL,
              sizeScale: 10,
              getOrientation: (d) => [0, d.Yaw, 90],
              getPosition: (d) => [d.Longitude, d.Latitude, d.Altitude],
              getColor: (d) => [238, 104, 103],
            }),
            new ScenegraphLayer({
              id: "home",
              data: this.filterByDate(),
              pickable: true,
              scenegraph: MODEL_URL,
              sizeScale: 10,
              getOrientation: (d) => [0, 0, 90],
              getPosition: (d) => [d.HomeLongitude, d.HomeLatitude, d.AltitudeHeight],
              getColor: (d) => [123, 67, 122]
            }),

Shouldnt the layers build up together instead of replacing each other over and over?

Not sure what you mean by “ they keep replacing each other.” Note that every time upd() is called you are restarting the fetching by creating a new async generator.

I called udp once and it makes once fetch and ill have this data

then it will switch to my other layer.

It will keep doing this over and over till the loop has stopped.
But when I use column layer I have no problem. both layers in the layer array load together as they should but only when I use scenegraph layer is when they replace each other. @Pessimistress
