Live update failed in non-uniform heatmap

I am implementing a waterfall chart with non-uniforma heatmap. I found that the live update doesn’t work. I keep updating the zValues with live data but the chart just show 1 row of data. If I resize the chart (my heatmap is inside a resizable container), I can see the updated data (i.e. Each time I resize the chart, the chart updated and show updated data). Do you have any example of live updated non-uniform heatmap? Below are my codes:

Draw the heatmap:

const SPECTROGRAM_HEIGHT = 256;
const SPECTROGRAM_WIDTH = 100;

const { sciChartSurface, wasmContext } = await SciChartSurface.create("spectrogram-chart-root");

const xAxis = new NumericAxis(wasmContext, {
    axisTitle: "Frequency",
    axisTitleStyle: {
        fontSize: CHART_STYLE.AXIS_FONT_SIZE,
        fontFamily: "sans-serif",
        fontWeight: "bold"
    },
    labelStyle: {
        fontSize: CHART_STYLE.LABEL_FONT_SIZE,
        fontFamily: "sans-serif"
    },
    labelFormat: ENumericFormat.Decimal,
    labelPrecision: 6,
    cursorLabelFormat: ENumericFormat.Decimal,
    cursorLabelPrecision: 6,
    drawMajorBands: false,
});

const yAxis = new NumericAxis(wasmContext, {
    axisTitle: "Time",
    axisTitleStyle: {
        fontSize: CHART_STYLE.AXIS_FONT_SIZE,
        fontFamily: "sans-serif",
        fontWeight: "bold"
    },
    labelStyle: {
        fontSize: CHART_STYLE.LABEL_FONT_SIZE,
        fontFamily: "sans-serif"
    },
    drawMajorBands: false,
});

// Add XAxis and YAxis
sciChartSurface.xAxes.add(xAxis);
sciChartSurface.yAxes.add(yAxis);

const colorMap = new HeatmapColorMap({
    minimum: -200,
    maximum: -50,
    gradientStops: [
    { offset: 0, color: "Transparent" },
    { offset: 0.01, color: COLORS.DARK_BLUE },
    { offset: 0.4, color: COLORS.BLUE },
    { offset: 0.5, color: COLORS.GREEN },
    { offset: 0.6, color: COLORS.YELLOW },
    { offset: 0.8, color: COLORS.RED },
    { offset: 1, color: COLORS.DARK_RED },
    ]
});

// Create a Heatmap Data-series. Pass heatValues as a number[][] to the UniformHeatmapDataSeries
zValues = Array.from(Array(SPECTROGRAM_HEIGHT), () => Array(SPECTROGRAM_WIDTH).fill(-200));

const heatmapSeries = new NonUniformHeatmapRenderableSeries(wasmContext, {
    dataSeries: new NonUniformHeatmapDataSeries(wasmContext, { zValues: zValues, xCellOffsets: getHeatmapXOffset, yCellOffsets: getHeatmapYOffset }),
    colorMap: colorMap,
    useLinearTextureFiltering: true,
    fillValuesOutOfRange: true,
});

// Add heatmap to the chart
sciChartSurface.renderableSeries.add(heatmapSeries);

I simply return the index for testing in the getHeatmapXOffset and getHeatmapYOffset functions:

    const getHeatmapXOffset = (index) => {
    return index;
};

const getHeatmapYOffset = (index) => {
    return index;
};

Reset zValues when number of data point changed:

        spectrogramZValues = Array.from(Array(SPECTROGRAM_HEIGHT), () => Array(newWidth).fill(-200));
        heatmapSeries.dataSeries.setZValues(spectrogramZValues);
        sciChartSurface.zoomExtents();

Update the zValues array when there is new data (I tried to add call zoomExtens() after notifyDataChanged but still didn’t work):

    spectrogramZValues.shift();
    spectrogramZValues.push(newData);
    heatmapSeries.current.dataSeries.notifyDataChanged();
