Lightningchart js, use different sampling rate in Medical Dashboard

Currently I have ECG, Pulse rate, Respiratory Rate and NIBP to show in LightningChart JS Medical Dashboard which used a global sampling rate which is common to all channels [ecg,pulseRate,respRate,nibp]. But the sampling rate would change for each channel. ECG and Pulse Rate will have 256, and Respiratory rate will have 128.

I tried below but didn’t work, as it now becomes 128 samples/second to all the channels.

Code:

 const SAMPLE_RATE_NEW = 128;

Below is the function i used with my changes.

    let tSamplePos = window.performance.now();
    let tSamplePosNew = window.performance.now();
    let iSampleX = 0;

    const addData = () => {
      const tNow = window.performance.now();
      const seriesNewPoints = seriesList.map((_) => []);
      while (tNow > tSamplePos) {
        const x = tSamplePos;
        const xNew = tSamplePosNew;
        for (let i = 0; i < seriesList.length; i += 1) {
          const channel = channels[i];
          const dataSet = channel.dataSet;
          const sample = dataSet[iSampleX % dataSet.length];
           if (i !== 2) {
             // @ts-ignore
             seriesNewPoints[i].push({ x, y: sample });
           } else {
             // @ts-ignore
             seriesNewPoints[i].push({ xNew, y: sample });
           }
          // // @ts-ignore
          //seriesNewPoints[i].push({ x, y: sample });
          if (channel.name === "Electrocardiogram") {
            updateBpm(sample);
          }
        }
        tSamplePos += 1000 / SAMPLE_RATE;
        tSamplePosNew += 1000 / SAMPLE_RATE_NEW;

        iSampleX += 1;
      }

How do i get different sampling rates in different channel?
I am using this medical dashboard Online Medical Dashboard

Entire Code can be found above.

I have tried multiple different solution but none of them worked. Need guidance on how to do it.

I tried using different sampling rate and push the data inside array, but i am not getting different sampling rates. Why I want this? The charts formed are different in different devices(laptop/desktop). And since this is a medical application, so its very urgent.
