    let metricArr = IdMetricMap[i];
    let metricVal = metricArr[1];
    let rgb = (scale(metricVal)).rgba();
    // convert color to 32bit little-endian value
    metricArr[1] = (rgb[3] << 24) + (rgb[2] << 16) + (rgb[1] << 8) + rgb[0];
    // make data key
    let idUint64 = new Uint64();
    idUint64.parseString(metricArr[0].toString());
    metricArr[0] = idUint64.low + ',' + idUint64.high;
    // convert val to Uint64 with rand high values
